Features


Your RadioShack PRO-92 500-Channel Portable Trunking
Scanner is one of a new generation of scanners designed
to track Motorola ® Type I and Type II (such as
Smartnet ® and Privacy Plus ® ) and hybrid analog trunking
systems, plus GE/Ericsson (EDACS ® ) and EF Johnson
(LTR ® ) type systems, which are extensively used in many
communication systems.

Trunking communications systems let a large group of 2- way radio users (or even different groups of 2-way radio users) efficiently use a set of frequencies. Instead of selecting a specific frequency for a transmission, the user simply selects a talk group. The trunking system automatically transmits the call on the first available frequency, and also sends a code that uniquely identifies that transmission. Since the trunking system might send a call and its response on different frequencies, it is difficult to listen to trunked communications using a regular scanner. The PRO-92 monitors the data sent with a 2-way radio transmission, so you can hear the call and response for that user and more easily follow the conversation. The scanner also lets you scan conventional transmissions, and is preprogrammed with service search banks for convenience. By pressing a single button, you can quickly search those frequencies most commonly used by public service and other agencies without tedious and complicated programming.

This scanner gives you direct access to over 33,000 frequencies including those used by police and fire departments, ambulance services, government agencies, air, and amateur radio services.

Your scanner includes these special features:

Simultaneous Trunking Operation tracks three trunking systems, LTR, Motorola, and EDACS at the same time, as well as conventional systems.

Text Input lets you input a text label for each channel, talk group ID, bank, or other memory so you can easily know about the transmission you are hearing.

Subaudible Tone Decode decodes and displays the Continuous Tone Coded Squelch System (CTCSS) tone signal being transmitted.

Digital Subaudible Tone Decode decodes and dis-plays the Digital Coded Squelch (DCS) being received.

12-Character, 4-Line, Dot-Matrix Display shows you detailed operating information and lets you easily pro-gram the scanner.

Data Cloning lets you transfer the programmed data to another PRO-92 scanner. You can also upload or download the programmed data to or from a PC using an optional interface kit.

10 Channel-Storage Banks let you store 50 channels in each bank to group channels so calls are easier to identify.

Triple Conversion Superheterodyne Receiver virtually eliminates any interference from intermediate frequency (IF) images, so you hear only the frequency you select.

Hyperscan TM and Hypersearch TM the scanner scans at up to 25 channels per second and searches at up to 50 steps per second, to help you quickly find interesting transmissions.

60 Preprogrammed Frequency Ranges - let you search for transmissions within preset frequency ranges or within ranges you set, to reduce search time and select interesting frequencies more quickly.

Scan Delay - delays scanning for about 2 seconds be-fore moving to another channel in conventional mode, so you can hear more replies that are made on the same channel.

Priority Channel - you can set the scanner to check one channel every 2 seconds so you do not miss impor-tant calls.

Signal Attenuation (Attenuate) - lets you program each memory to reduce the scanner’s sensitivity to strong local signals, to reduce interference or noise caused by these signals.

Weather Alert - automatically sounds the alarm tone to advise of hazardous weather conditions when it detects the alert signal on the local National Oceanic and Atmospheric Administration (NOAA) weather channel.

Weather SAME Decode - displays the weather event text so you can see the reason for the alert.

Lock out Function - lets you set your scanner to skip over specified channels or frequencies when scanning or searching, and skip over IDs when tracking trunked systems.

Key Lock - lets you lock the scanner’s keys to help prevent accidentally changing the scanner’s programming.

Flexible Antenna with BNC Connector - provides excellent reception and is designed to help prevent antenna breakage.

Memory Backup - keeps the frequencies stored in memory for an extended time even without a battery.

Page 4


Three Power Options - let you power the scanner with internal batteries (non-rechargeable batteries or re-chargeable batteries). You can also use an AC adapter (not supplied) or power the scanner in a vehicle using a DC adapter (not supplied).

Supplied Police Call Trunking Guide - provides a quick reference to public safety trunking radio systems in the United States.

Your PRO-92 scanner can receive these frequencies:

This Owner’s Manual also includes the section A General Guide to Scanning on Page 65 to help you target frequency ranges in your service area so you can search for a wide variety of transmissions.

FCC NOTICE

Your scanner might cause TV or radio interference even when it is operating properly. To determine whether your scanner is causing the interference, turn off your scanner. If the interference goes away, your scanner is causing the interference. Try the following methods to eliminate the interference.

Page 5

If you cannot eliminate the interference, the FCC requires that you stop using your scanner.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions: (1) This de-vice must not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Note: Mobile use of this scanner is unlawful or requires a permit in some areas. Check the laws in your area.

SCANNING LEGALLY

Scanning is a fun and interesting hobby. You can hear police and fire departments, ambulance services, government agencies, private companies, amateur radio services, aircraft, and military operations. It is legal to listen to almost every transmission your scanner can receive. However, there are some electronic and wire communications that are illegal to intentionally intercept. These include:

  • telephone conversations (cellular, cordless, or other private means of telephone signal transmission)
  • pager transmissions
  • scrambled or encrypted transmissions

    According to the Federal Electronic Communications Privacy Act (ECPA), as amended, you could be fined and possibly imprisoned for intentionally listening to, using, or disclosing the contents of such a transmission unless you have the consent of a party to the communication (unless such activity is otherwise illegal). These laws change from time to time and there might be state or local laws that also affect legal scanner usage.

    PREPARATION

    POWER SOURCES
    You can power your scanner from any of three sources:
    Notes:

    Using Batteries

    You can power the PRO-92 with six AA batteries. For the longest operation and best performance, we recommend alkaline batteries, available at your local RadioShack store.
    You can use either the supplied non-rechargeable black battery holder, or the supplied rechargeable yellow battery holder. If you use the rechargeable battery holder, we recommend RadioShack nickel-cadmium or nickel-metal hydride batteries.

    Page 10


    Warning: Never install non-rechargeable batteries in the rechargeable yellow battery holder. Non-rechargeable batteries can get hot or explode if you try to recharge them.

    Note: You must charge rechargeable batteries before you use them the first time. See Charging Rechargeable Batteries on Page 13. Follow these steps to install the batteries.
    1. Press down on the battery compartment cover on the bottom of the scanner and slide the cover in the direction of the arrow to remove it.

    4. Slide the battery holder into the compartment.

    Picture missing
    Caution: The battery holder fits only one way. Do not force it. 5. Replace the cover.

    Page 12


    When battery power is low, Low Battery! appears and the scanner beeps continuously. When battery power is depleted, the scanner turns itself off. Replace all six non-rechargeable batteries, or recharge the rechargeable batteries. See Charging Rechargeable Batteries.

    Warning: Always dispose of old batteries promptly and properly. Do not bury or burn them.

    Caution: If you do not plan to use the scanner with batteries for a month or longer, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

    Charging Rechargeable Batteries

    Your scanner has a built-in charging circuit that lets you charge rechargeable batteries (not supplied) while it is in the scanner. To charge rechargeable batteries connect an appropriate AC or DC adapter to the PWR DC 9V jack. We recommend RadioShack rechargeable batteries.

    Note: To charge batteries with a DC adapter from a DC power source, you must use RadioShack Cat. No. 273- 1825 and a size H Adaptaplug ® (neither supplied) available at your local RadioShack store. Make sure the adapter’s voltage is set to 10V.

    It takes between 14-16 hours to recharge rechargeable batteries that are fully discharged. You can operate the scanner while recharging the rechargeable batteries, but charging takes longer.

    Notes:

    Page 13


    Important: This scanner can use nickel-cadmium rechargeable batteries. At the end of a nickel-cadmium battery's useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area or call 1-800-843-7422. Some options that might be available are: municipal curb-side collection, drop-off boxes at retailers such as your local RadioShack store, recycling collection centers, and mail-back programs.

    Using AC Power

    You can power the scanner using an 9V, 300 mA AC adapter and a size H Adaptaplug (neither supplied). We recommend RadioShack Cat. No. 273-1767 (available at your local RadioShack store).

    Cautions: You must use a Class 2 power source that supplies 9V DC and delivers at least 300 mA. Its center tip must be set to negative and its plug must fit the scanner's PWR DC 9V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

    Follow these steps to connect the adapter.
    1. Connect the Adaptaplug to the adapter’s cord with the tip set to negative. Page 14


    2. Plug the adapter’s barrel plug into the scanner’s PWR DC 9V jack. 3. Plug the adapter into a standard AC outlet.

    Using Vehicle Power

    You can power the scanner from a vehicle’s 12V power source (such as a cigarette-lighter socket) using a 9V, 300 mA DC adapter and a size H Adaptaplug (neither supplied). We recommend RadioShack Cat. No. 273- 1810 (available at your local RadioShack store).

    Note: For charging batteries with an optional DC adapter from a DC power source, use RadioShack Cat. No. 273- 1825 and a size H Adaptaplug (available at your local RadioShack store). Make sure the adapter’s voltage is set to 10V.

    Cautions:

    You must use a power source that supplies 9V DC and delivers at least 300 mA. Its center tip must be set to negative and its plug must fit the scanner's PWR DC 9V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter.


    Follow these steps to connect the adapter.
    1. Connect the Adaptaplug to the adapter’s cord with the tip set to negative.
    2. Plug the adapter’s barrel plug into the scanner’s PWR DC 9V jack.
    Page 15

    3. Plug the adapter’s cigarette-lighter plug into your vehicle’s cigarette-lighter socket.
    Picture missing
    Note: If the scanner does not operate properly when you connect a DC adapter, unplug the DC adapter from the cigarette-lighter socket and clean the socket to remove ashes and other debris.

    CONNECTING THE ANTENNA

    Follow these steps to attach the supplied flexible antenna to the ANT jack on the top of your scanner.

    Picture missing
    1. Align the slots around the antenna’s connector with the tabs on the ANT jack.
    2. Press the antenna down over the jack and turn the antenna’s base clockwise until it locks into place.
    Page 16


    Connecting an Optional Antenna

    The antenna connector on your scanner makes it easy to use the scanner with a variety of antennas, such as an external mobile antenna or outdoor base station antenna. Your local RadioShack store sells a variety of antennas. Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable. If your antenna’s cable does not have a BNC connector, you will also need a BNC adapter (also available at your local RadioShack store).

    Follow the installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the ANT jack.

    Warning: Use extreme caution when installing or removing an outdoor antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with the antenna, mast, cable or guy wires can cause electrocution and death! Call the power company to remove the antenna. Do not attempt to do so yourself.

    CONNECTING AN EARPHONE/HEADPHONES

    For private listening, you can plug an earphone or mono/ stereo headphones (not supplied), available at your local RadioShack store, into the jack on top of your scanner. This automatically disconnects the internal speaker.

    Picture missing
    Page 17


    Listening Safely

    To protect your hearing, follow these guidelines when you use an earphone or headphones:

    Traffic Safety

    Do not wear an earphone or headphones while you drive a vehicle or ride a bicycle. This can create a traffic hazard and can be illegal in some areas.

    Even though some earphones and headphones let you hear some outside sounds when you listen at normal levels, they still can present a traffic hazard.

    CONNECTING AN EXTENSION SPEAKER

    In a noisy area, an amplified speaker (not supplied), available at your local RadioShack store, might provide more comfortable listening. Plug the speaker cable’s 1 /8-inch (3.5-mm) mini-plug into your scanner’s headphone jack.

    Picture missing
    Page 18


    USING THE BELT CLIP

    You can use the belt clip attached to the back of the scanner for hands-free carrying when you are on the go. Slide the belt clip over your belt or waistband.

    CONNECTING THE CLONE CABLE

    You can transfer the programmed data to and from an-other PRO-92 using the supplied clone cable. Connect the cable between each scanner’s PC/IF jacks. See

    Page 19


    ABOUT YOUR SCANNER

    Once you understand a few simple terms used in this manual and familiarize yourself with your scanner’s features, you can put the scanner to work for you. You simply determine the type of communications you want to receive, then set the scanner to scan them.

    A frequency is the receiving signal location (expressed in kHz or MHz). To find active frequencies, you can use the search function.

    You can also search the SEARCH banks, which are preprogrammed frequencies in the scanner’s memory (see Searching a Preprogrammed Frequency Range on Page 41 for the frequency list). You can change the SEARCH frequency ranges.

    When you find a frequency, you can store it into a programmable memory location called a channel, which is grouped with your other channels in a channel-storage bank. You can then scan the channel-storage banks to see if there is activity on the frequencies stored there. Each time the scanner finds an active frequency, it stays on that channel until the transmission ends. See Trunk-ing Operation on Page 57 for terms related to trunking systems.

    A LOOK AT THE KEYPAD

    Your scanner’s keys might seem confusing at first, but this information should help you understand each key’s function.

    UNDERSTANDING BANKS

    Channel Storage Banks
    To make it easier to identify and select the channels you want to listen to, channels are divided into 10 banks (0-9) of 50 (00 to 49) channels each. Use each channel-storage bank to group frequencies, such as those used by the police department, fire department, ambulance services, or aircraft (see Guide to the Action Bands on Page 67). For example, the police department might use four frequencies, one for each side of town. You could program the police frequencies starting with 000 (the 1st channel in bank 0) and program the fire department fre-quencies starting with 100 (the 1st channel in bank 1). The 1st digit identifies the bank (0-9). The 2nd and 3rd digits identify the channel within the bank (00-49).

    Search Banks

    This scanner is able to search 10 search banks. You can also replace a bank with one of the 60 pre-programmed service bands. (For the default setting, see Searching a Preprogrammed Frequency Range on Page 41).

    The following list shows the 60 pre-programmed service bands

    Please click here to view the Scanner Search Tables



    UNDERSTANDING YOUR PRO-92’S MODES

    You can program each channel with any of seven receive modes. Each mode affects how your scanner operates when scanning and receiving transmissions, and also affects what transmissions you receive when you set the scanner to the Closed mode (see Open and Closed Modes on Page 63). The following sections describe each mode and how they affect your scanners operation. See Changing the Receive Mode on Page 53.

    PL, DPL and trunking systems all use some form of coded squelch. Coded squelch techniques involve the transmission of a special code signal along with the audio of a radio transmission. A receiver with coded squelch only activates when the received signal has the correct code. This lets many users share a single frequency, and de-creases interference caused by distant transmitters on the same channel.

    In all major metropolitan areas of the United States, every available radio channel is assigned to more than one user. Public safety radio systems on the same frequency are usually set up at a distance of forty miles apart, or more. This means that you may hear transmissions from a distant system when your local system is not transmitting. By entering the PL for a local system, and operating the bank in closed mode, the scanner will not stop on transmissions from the distant system.

    Page 28


    With few exceptions, such as the VHF Aircraft and Marine bands, almost every other VHF or UHF radio system uses some form of coded squelch. By far, PL is the most popular mode among non-trunked systems. For most scanning use, try setting PL mode for all non-trunked channels. If you operate the bank in open mode, the scanner will display the appropriate code.

    AM Mode

    This sets the scanner to receive transmissions using amplitude modulation (AM). AM is used for aircraft, military, some amateur radio, and some government transmissions. When the scanner receives a transmission on a channel set to the AM mode, it always stops on the transmission.

    FM Mode

    This sets the scanner to receive transmissions using frequency modulation (FM). FM is used for most public safety transmissions, as well as broadcast, business, and amateur radio transmissions. When the scanner receives a transmission on a channel set to the FM mode, it always stops on the transmission.

    CODED SQUELCH MODES (PL, DPL, AND TRUNKING)

    PL Mode

    This sets the scanner to decode subaudible tones that are transmitted with many FM transmissions. Radio system users use these tones to allow multiple users to share a single frequency and to prevent interference from other systems operating nearby on the same frequency. When you select the PL mode for a channel, you can also set a specific PL tone for that channel.

    page 29


    When the scanner receives a transmission on a channel set to the PL mode, it first decodes the PL tone included with the transmission. In the Open mode, the scanner stops on the transmission and displays the PL tone on the bottom line of the display (or displays None if no tone is included). In the Closed mode, the scanner only stops on the transmission if the PL tone matches the tone that you specified for the channel.

    PL tones range in frequency from 67 Hz to 254.1 Hz. You select a PL tone by pressing STEP while programming a channel.

    DPL Mode

    This sets the scanner to decode digital PL tones used with some FM transmissions. Similar to PL, DPL is a digital signature encoded on a subaudible carrier. In addition to preventing interference from other nearby radio systems, DPL can also identify a specific user or group of users on a radio system. When you select the DPL mode for a channel, you can also set a specific DPL code for that channel.

    When the scanner receives a transmission on a channel set to the DPL mode, it first decodes the DPL code included with the transmission. In the Open mode, the scanner stops on the transmission and displays the DPL code on the bottom line of the display (or displays None if no code is included). In the Closed mode, the scanner only stops on the transmission if the DPL code matches the code that you specified for the channel.

    DPL codes range from D017 to D754 (only 100 codes are actually used within this range). You select a DPL code by pressing STEP while programming a channel.

    DPL is not as popular as PL, because the effective range of DPL-encoded signals is less than PL.

    Page 30


    LTR (E. F. Johnson) Mode

    This sets the scanner to decode the talk group ID’s used with an LTR system. This is a trunking system used primarily by business or private communications service providers, such as taxi cabs, delivery trucks, and repair services. LTR systems encode all trunking information as digital subaudible data that accompanies each transmission. Users on an LTR system are assigned to specific talk groups, which are identified by the radio as a six-digit number. The number is in the form:

    AHHUUU

    Where:

    A = Area code (0 or 1)

    H = Home repeater (01 through 20)

    U = User ID (000 through 254)

    When the scanner receives a transmission on a channel set to the LTR mode, it first decodes the LTR data included with the transmission. In the Open mode, the scanner stops on the transmission and displays the talk group ID on the bottom line of the display. In the Closed mode, the scanner only stops on the transmission if the LTR data matches a talk group ID that you have stored in the bank’s talk group ID list and have not locked out.

    LTR systems are frequently programmed so that each radio has a unique ID code.

    Page 31


    Motorola Mode

    This sets the scanner to decode the talk group ID’s used with Motorola trunking systems. These systems are used by business and public safety groups to efficiently allocate a small number of frequencies (as few as 5) to many groups of users (as many as several thousand). To do this, each group of users in the system is assigned to a specific talk group. For example, the east side patrol officers might all be assigned to talk group 2160. One channel in the system is continuously transmitting data that identifies which talk groups are active on which channel.

    In addition, this talk group information is also transmitted as subaudible data on each active channel.

    When the scanner receives a transmission on a channel set to the Motorola mode, it first decodes the talk group ID data included with the transmission. In the Open mode, the scanner stops on the transmission and dis-plays the talk group ID on the bottom line of the display. In the Closed mode, the scanner only stops on the trans-mission if the talk group ID matches a talk group ID that you have stored in the bank’s talk group ID list and have not locked out.

    Motorola trunking systems come in three flavors: Type I, Type II, and Type I/II Hybrids. Each type displays and uses talk group ID’s in slightly different ways.

    Motorola Type I ID’s are in the form FFF-SS, where:

    FFF= Fleet ID

    SS= Subfleet ID

    Type I systems are usually organized with different user groups assigned to different fleets. For example, all po-lice users might be grouped under fleet 000. Then, within each fleet, subfleet ID’s are assigned to subgroups of the main user group.

    Page 32


    For example, Police - East Patrol might be assigned to group 12, making the full Fleet, Subfleet ID be 000-12. To properly map the raw Type I data to the correct fleet-subfleet format, you must program the correct fleet map into the scanner. Fleet map information is widely available on the internet for most Type I systems in use.

    Type II systems talk groups are identified by a 5-digit number. Valid talk group IDs are divisible by 16. If you try to enter an invalid talk group ID, the scanner rounds the ID down to the next valid ID.

    Type I/II hybrid systems use both fleet-subfleet and 5-dig-it formats for talk group ID’s.

    Note: Since the subaudible data is included with every transmission, you can generally receive Motorola sys-tems from further away than when using systems that only decode the data channel (like the EDACS mode). However, as the signal quality worsens, or if the signal is subject to interference, the scanner might not be able to reliably decode the talk group ID. In this case, you might occasionally notice that the talk group ID changes during a transmission.

    EDACS Mode

    This sets the scanner to decode the talk group ID’s used with an EDACS (GE/Ericsson) system. This is a trunking system used primarily by business or private communications service providers, as well as by some public safety organizations. EDACS systems transmit active talk group information only on a dedicated control channel.

    EDACS frequencies are organized in a specific order. Each frequency is assigned a Logical Channel Number (LCN). For the PRO-92 to correctly switch to an active frequency, you must program the frequencies in LCN order, starting with Memory 01. EDACS talk group ID’s are entered as a 4-digit decimal number from 0000 to 4096.

    Page 33


    When there is activity on an EDACS system, that information is sent out on the control channel. The scanner decodes the ID for the active talk group. In the Open mode, the scanner then goes to the transmission and displays the talk group ID on the bottom line of the display. In the Closed mode, the scanner only goes to transmissions that have ID’s that match a talk group ID that you have stored in the bank’s talk group ID list and have not locked out.

    Because EDACS scanning requires you to have clear reception of the control channel at all times, EDACS systems tend to have a smaller usable area. An external antenna can greatly improve EDACS scanning in a fringe area. If you are having trouble scanning an EDACS system, try manually selecting the data channel. If you are getting good reception, the scanner will indicate talk group CTR-01. Try changing your location or using an outdoor antenna to improve reception.

    LISTENING TO THE WEATHER BAND

    The FCC (Federal Communications Commission) has allocated channels for use by the National Oceanic and Atmospheric Administration (NOAA). Regulatory agencies in other countries have also allocated channels for use by their weather reporting authorities.

    NOAA and your local weather reporting authority broadcast your local forecast and regional weather information on one or more of these channels.

    Listening to a Weather Channel

    To hear your local forecast and regional weather information, press WX. Your scanner scans through the weather band. Your scanner stops within a few seconds on your local weather broadcast.

    Page 46


    Weather Alert Feature

    This scanner can detect both the weather alert tone and can decode the digital SAME message that precedes each alert. If you are monitoring a weather channel when an alert is broadcast, the scanner sounds an alert and displays the type of alert being broadcast.

    The weather service precedes each weather alert with a digitally-encoded SAME signal, then a 1050 Hz tone. The PRO-92 responds to each signal. You can receive weather alerts any of three ways.

    Notes:

    When it decodes SAME, it displays the specific type of weather event (or Tune to TV or Radio) if it does not recognize the event code. When it detects the 1050 Hz tone, it displays Weather Alert? In either case, the scanner also sounds an alert tone.

    To obtain SAME codes, visit the National Weather Service web site at:

    http://www.nws.noaa.gov/nwr/indexnw.htm#sametable

    SPECIAL FEATURES


    USING THE DELAY FUNCTION

    Note: The delay function turns on automatically when you turn on the scanner.

    Many conversations might have a pause of several seconds between a query and a reply. To avoid missing a reply, you can program a 2-second delay into any of your scanner’s channels. Then, when the scanner stops on the channel, D appears on the display and the scanner continues to monitor the channel for 2 seconds after the transmission stops before it resumes scanning or searching. You can program a 2-second delay in any of three ways.

    LOCKING OUT CHANNELS OR FREQUENCIES

    You can scan existing channels or search frequencies faster by locking out channels or frequencies that have a continuous transmission, such as a weather channel.

    PRIORITY

    With the priority feature, you can scan through programmed channels and still not miss an important or interesting call on a specific channel. When a channel is selected as the priority channel and priority is turned on, the scanner checks that channel every 2 seconds, and stays on the channel if there is activity until the activity stops.

    The scanner is preset to select Channel 00 in Bank 8 as the priority channel. You can program a different channel as the priority channel. Also, you can program a weather channel as the priority channel.

    Notes:

    Follow these steps to program a channel as the priority channel.

    1. Press MANUAL.

    2. Use the number keys to enter the channel number you want to program as the priority channel. Then press MANUAL again.

    3. Press FUNC then press PRI. Pri appears on the display to the right of the frequency.

    146.8000 Pri
    Bank  0  Ch 08
    Page 51


    Note: This scanner cannot set a channel as the priority channel if the channel’s receive mode is LTR, MOT, or ED.

    Follow these steps to program a weather channel as the priority channel.

    1. Press WX.

    2. Select the weather channel you want to program as the priority channel.

    3. Press FUNC then press PRI. Pri appears on the display to the right of the frequency.

    To turn on the priority feature, press PRI while scanning. Priority ON (or Priority WX if you set the priority to a weather channel) appears for about 3 seconds then P appears. The scanner checks the priority channel every 2 seconds. It stays on the channel if there is activity (or if it detects a weather alert tone in priority wx mode), Pri appears and S or M changes to P on the display.

    Notes:

    To turn off the priority feature, press PRI. Priority OFF appears on the display and P disappears from the display.

    Note: The priority channel is always active if it is in the closed mode, regardless of the open or closed setting for the bank. This means that if the priority channel is PL, and has a PL code stored for it, the priority function will not be active unless the priority signal has the matching PL code.

    Page 52


    CHANGING THE RECEIVE MODE

    The scanner is preset to the most common AM or FM receive mode for each frequency range. The preset mode is correct in most cases. However, some amateur radio transmissions and trunked systems do not operate in the preset mode. If you try to listen to a transmission when the scanner is not set to the correct receive mode, the transmission might sound weak or distorted. If you want to listen to and watch the private line or trunking transmission in the closed mode, you need to change the receive mode. (PL, DPL, MOT, LTR, and ED all use FM).

    You can change a receive mode by pressing MODE. The receive mode changes as follows:

    Display   Description
    AM AM Mode
    FM FM Mode
    PL FM Mode, Private Line (with 67.0-254.1 Hz PL code).
    DL FM Mode, Digital Private Line (with 3-digit DPL code).
    LT FM Mode, LTR Trunking System (with 6-digit ID code).
    MO FM Mode, Motorola Trunking System (with a 4- or 5-digit ID code).
    ED FM Mode, EDACS Trunking System (with 4-digit ID code).

    TRUNKING OPERATION

    The PRO-92 scanner tracks transmissions that use the Motorola ® Type I and Type II (such as Smartnet and Privacy Plus) and hybrid analog trunking systems, plus GE- Ericsson (EDACS) and EF Johnson (LTR) type systems, which are extensively used in many communication sys-tems. Trunking systems allocate a few frequencies to many different users. When the mobile unit transmits a signal, one frequency is chosen from among the allocated frequencies in that trunking system. The user’s ID talk group is sent with the signal.

    Trunking group frequencies are included in the supplied Police Call Trunking Guide. Frequency fleet map and talk group information is also widely available on the Internet, including at www.trunkscanner.com.

    UNDERSTANDING TRUNKING

    In the past, groups that transmit frequently, such as police departments, were restricted to transmitting on just a few frequencies. This resulted in heavy traffic and often required 2-way radio users to wait for a specific frequency to clear before transmitting.

    Trunked systems allow more groups of 2-way radio users to use fewer frequencies. Instead of selecting a specific frequency to transmit on, a trunked system chooses one of several frequencies when the 2-way radio user presses PTT (push to talk). The system automatically transmits the call on that frequency, and also sends a code that identifies that 2-way radio user’s transmission on a control channel.

    This scanner lets you easily hear both the call and response transmissions for that 2-way radio user and therefore follow the conversation. For Motorola and LTR systems, the scanner uses the subaudible data sent with each transmission to identify talk groups. For EDACS, the scanner monitors the control channel between each transmission to identify talk groups.

    162.425 162.500 162.550
    162.450

    Ham Radio Frequencies

    Ham radio operators often transmit emergency information when other means of communication break down. The chart below shows the frequencies the scanner receives that ham radio operators normally use:

    Wavelength Frequencies (MHz)
    10-Meter 29.000-29.700
    6-Meter50.000-54.000
    2-Meter144.000-148.000
    70-cm420.000-450.000
    33-cm902.000-928.000

    Birdie Frequencies
    Every scanner has birdie frequencies. Birdies are signals created inside the scanner’s receiver. These operating frequencies might interfere with transmissions on the same frequencies. If you program one of these frequen-cies, you hear only noise on that frequency. If the interfer-ence is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie.

    Page 65


    This scanner’s birdie frequencies (in MHz) are:

    29.0000 147.7650 415.3375 475.2375
    31.9500 150.1500 419.3375 479.2375

    FREQUENCY CONVERSION

    The tuning location of a station can be expressed in frequency (kHz or MHz) or in wavelength (meters). The following information can help you make the necessary conversions.

    1 MHz (million) = 1,000 kHz (thousand)

    To convert MHz to kHz, multiply the number of megahertz by 1,000:

    30.62 (MHz) X 1000 = 30,620 kHz

    To convert from kHz to MHz, divide the number of kilohertz by 1,000:

    127,800 (kHz) / 1000 = 127.8 MHz

    To convert MHz to meters, divide 300 by the number of megahertz:

    300 / 50 MHz = 6 meters

    TROUBLESHOOTING


    If you have problems with your scanner, here are some suggestions that might help you eliminate the problem. If they do not, take your scanner to your local RadioShack store for assistance.

    Problem Possible Cause Remedy

    RESETTING/INITIALIZING THE SCANNER

    If the scanner’s display locks up or does not work proper-ly after you connect a power source, you might need to reset or initialize it.

    Important: If you have problems with the scanner, first try to reset it to retain all memory. If that does not work, you can initialize the scanner; however, initializing clears all information stored in the scanner’s memory.

    Resetting the Scanner

    1. Turn off the scanner, then turn it on again.

    2. Insert a pointed object, such as a straightened paper clip, into the reset opening on the side of the scanner. Then gently press and release the reset button inside the opening and the backlight lights.

    Note: Pressing RESET does not clear the scanner’s memory.

    Initializing the Scanner

    Important: This procedure clears all information you stored in the scanners memory. Initialize the scanner only when you are sure the scanner is not working properly.

    1. Turn off the scanner, then turn it on again. Welcome To Multi-System Trunking appears on the display.

    Page 75


    2. Press 0 then 1 while the display shows Welcome To Multi-System Trunking. Initializing Please Wait. appears on the display about 25 seconds.

    Note: Do not turn off the scanner until the initialization is complete and Welcome To Multi-System Trunking appears again.

    CARE AND MAINTENANCE

    Your RadioShack PRO-92 500-Channel Portable Trunking Scanner is an example of superior design and craftsmanship. The following suggestions will help you care for your scanner so you can enjoy it for years.

    Keep the scanner dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits.

    Use only batteries of the recommended size and type. Always remove old and weak batteries. They can leak chemicals that de-stroy electronic circuits.

    Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can cause the scanner to work improperly.

    Use and store the scanner only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.

    Keep the scanner away from dust and dirt, which can cause premature wear of parts. Wipe the scanner with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the scanner.

    Modifying or tampering with the scanner’s internal com-ponents can cause a malfunction, invalidate your scanner’s warranty and void your FCC authorization to operate it. If your scanner is not operating as it should, take it to your local RadioShack store for assistance.
