20-428 Owner’s Manual Page 3 of 50 install your scanner You can mount your multi Trunking scanner in your vehicle, install it for mobility, or install it as a base station. mounting your scanner in your dashboard If you are unsure about how to install your scanner in your vehicle, consult your automobile manufacturer, dealer, or a qualified installer. Before installing, confirm your scanner fits in the desired mounting area and you have all the necessary materials. Your scanner requires a 2 x 7 1/8 x 5 5/16 inch (50 x 180 x 135 mm) mounting area. 1. Remove the four rear screws and pull off the black case before installing your scanner. 2. Install the DIN sleeve into the opening in your dashboard, lip facing out. 3. Push out the top and bottom tabs to hold the sleeve firmly in place. 4. Slide the scanner into the sleeve until it locks in place. Notes: • To remove your scanner from the DIN sleeve, insert the two keys straight into the scanner’s front panel. Then, remove the scanner by pulling front panel. • When mounting in your dashboard, you will need to connect an external antenna and an external speaker. mobile mounting in your vehicle You can mount your scanner under the dashboard, or on top of it, using the mounting bracket. 1. Attach the three protective rubber feet to the mounting bracket when you use the scanner on a flat surface. Do not use them when you mount the bracket with screws. 2. Use the supplied mounting bracket as a template to mark positions for the two mounting screws. 3. At the marked positions, drill holes slightly smaller than the screws. 4. Remove the paper backing from each washer and stick one inside of each bracket’s ear, aligning the washer’s hole with the bracket’s hole. 5. Attach the mounting bracket to your vehicle’s surface using the supplied screws and lockwashers.
20-428 Owner’s Manual Page 4 of 50 6. Slide the scanner into the bracket, aligning the scanner’s holes with the holes in the bracket, and then screw the mounting knobs into the scanner. Note: When drilling holes, be sure to avoid obstructions behind the mounting surface. Consult a qualified installer if in doubt. using your scanner as a base station You can place your scanner on a desk, shelf, or table to use it as a base station. Since the speaker is on the bottom of the scanner, you may want to use the mounting bracket to elevate your scanner off the surface for better sound. Follow the mobile vehicle mounting instructions above to affix your scanner to a desk, shelf, table or other flat surface (except that the bracket will be below the scanner). power your scanner You can power your scanner from a wall outlet, through your vehicle’s ignition, or from your vehicle’s cigarette lighter. from a wall outlet add photograph 1. Connect the tip of the supplied AC adapter to the DC 13.8V jack at the rear of your scanner. 2. Plug the AC adapter into your wall outlet. Note: You must use a Class 2 power source that supplies 13.8V DC and delivers at least 600mA. Its center tip must be set to positive and its plug must fit the scanner’s DC 13.8V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter. Warning! To prevent electric shock, do not use the AC adapter’s polarized plug with an extension cord, receptacle, or other outlet unless you can fully insert the blades to prevent blade exposure. through your vehicle’s ignition 1. Disconnect the cable from the negative (–) terminal of your vehicle’s battery. 2. Ground the black wire of the supplied DC power cord to your vehicle’s chassis. Note: Be sure the grounding screw makes complete contact with the metal frame of your vehicle.
20-428 Owner’s Manual Page 5 of 50 3. Connect the red wire of the supplied DC power cord to a voltage source that turns on and off with the ignition switch, such as a spare accessory terminal in your vehicle’s fuse box. 4. Insert the power cord’s barrel plug into the scanner’s DC 13.8V jack. 5. Reconnect the cable to the negative (–) terminal of your vehicle’s battery. Note: You must use a power source that supplies 12V DC and delivers at least 600mA. Its center tip must be set to positive and its plug must fit the scanner’s DC 13.8V jack. The supplied DC power cord meets these specifications. Using a power cord that does not meet these specifications could damage the scanner or the adapter. from your vehicle’s cigarette lighter To power your scanner from a 12V power source in your vehicle, such as a cigarette-lighter socket, you need a 12V, 600mA DC cigarette-lighter adapter (not supplied), available at your local RadioShack store. 1. Insert the adapter’s barrel plug into the scanner’s DC 13.8V jack. 2. Plug the adapter’s other end into your vehicle’s cigarette lighter or power socket. Note: When you use a cigarette-lighter adapter, you might hear electrical noise from your engine while scanning. This is normal. connect the supplied antenna Push the antenna onto your scanner’s antenna connector and rotate until it locks into place. Your scanner’s sensitivity to various frequencies depends on its location and the antenna’s length. For best reception, adjust the antenna’s length as follows: Frequency Antenna Length 25–54 MHz Extend fully 108–174 MHz Extend 4 segments 216–225 MHz Extend 3 segments 225-406 MHz Extend 2 segments 406-1300 MHz Collapse fully connect an external antenna You will need to connect an external antenna when you mount your scanner in the dashboard of
20-428 Owner’s Manual Page 6 of 50 your vehicle. You may also want to connect an external antenna if you use your scanner as a base station. 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 exceeding 50 feet, use RG-8 low-loss dielectric coaxial cable. If your coaxial cable does not have a BNC connector, you will also need a BNC adapter (not supplied). 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, touching 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. connect an external speaker or headphones When you mount your scanner in your dashboard, you will need to connect an external speaker or headphones. add photograph listening safely To protect your hearing, follow these guidelines when you use headphones. • Adjust VOL (volume) to its lowest level before putting on headphones. With the headphones on, adjust VOL to a comfortable level. • Avoid increasing the volume once you set it. Over time, your sensitivity to volume decreases, so volume levels that do not cause discomfort might damage your hearing. • Avoid listening at high volume levels. Prolonged exposure to high volume levels can cause permanent hearing loss. traffic safety Do not wear headphones while driving. This can create a traffic hazard and is illegal in some areas. Even though some headphones let you hear outside sounds when you listen at normal levels, they still can present a traffic hazard. quick start To help familiarize yourself with the scanner’s functions, keypad, and available frequencies, you can utilize one of these four features before you begin programming the scanner.
20-428 Owner’s Manual Page 7 of 50 Signal Stalker II – searches nearby strong signals quickly. See “Signal Stalker II”. Preprogrammed Search Banks – allow you to listen to frequencies and decide which frequencies you want to store when you are ready to program the scanner. See “Searching a Preprogrammed Frequency Range”. Manual Tuning – allows you to manually move through the entire range of available frequencies. (See “Specifications” for a list of the available frequency Ranges.) Weather Radio – allows you to listen to NOAA weather broadcasts without programming. See “Listening to the Weather Band”. understanding your scanner’s modes You can program each channel with any of seven receive modes (AM, FM, CT, DC, MO, ED, and LT). Each receive mode affects how your scanner operates when scanning and receiving transmissions. Notes: • Trunked modes (MO, ED, and LT) can only be selected for frequencies above 137 MHz. • Your scanner’s closed mode lets you hear only those Trunking talkgroups you specify. For more information, see “Open and Closed Modes”. AM mode The AM mode sets the scanner to receive transmissions using amplitude modulation (AM), primarily used for aircraft, military, some amateur radio, and some government transmissions. (Refer to “Specifications” for a list of the frequencies covered.) When the scanner receives a transmission on a channel set to the AM mode, it always stops on the transmission. FM mode The FM mode sets the scanner to receive transmissions using frequency modulation (FM), 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. CTCSS (CT) mode CTCSS mode sets the scanner to receive transmissions using frequency modulation (FM) with Continuous Tone Coded Squelch System (CTCSS) subaudible tone codes. CTCSS allows multiple users to share a single radio frequency without hearing each other’s transmissions. In your PRO-2055 scanner, the CTCSS feature can be used to block the reception of transmissions on shared channel to only those that use the CTCSS mode also features a Code Search setting that allows you to instantly display and store unknown codes into the channel memory. CTCSS tones can sometimes
20-428 Owner’s Manual Page 8 of 50 be heard as a low “hum” in the background of a voice transmission. DCS (DC) mode DCS mode sets the scanner to receive transmissions using frequency modulation (FM) with Digital Coded Squelch (DCS) subaudible data signaling. DCS is very similar to CTCSS, except that a digital code is transmitted instead of an audio tone. Like CTCSS, DCS allows multiple users to share a single radio frequency without hearing each other’s transmissions. In your PRO-2055 scanner, the DCS feature can be used to block the reception of transmissions on a shared channel to only those that use the DCS tone that you have specified. DCS mode also features a Code Search setting that allows you to instantly display and store unknown codes into the channel memory. DCS data can sometimes be heard as a low “purring” sound in the background of a voice transmission. Some DCS systems transmit a special “turn off code” at the end of each transmission. The turn off code causes a properly equipped receiver to mute before the transmission ends, eliminating the “squelch tail” burst of noise the commonly occurs when the signal is lost. Motorola mode You can set your scanner so it decodes the talk group IDs used with Motorola Trunking systems. This setting is called the Motorola mode. Motorola systems are Trunking systems used primarily by business and public safety groups to efficiently allocate a small number of frequencies (as few as five) 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 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 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 categories: Type I, Type II, and Type I/II Hybrid. Each category displays and uses talk group IDs in slightly different ways. Motorola Type II IDs 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. Notes:
20-428 Owner’s Manual Page 9 of 50 • For example, a valid fleet-subfleet ID identifying all detectives within a police department might be 000-12, where 000 identifies all police users and 12 identifies the Detective division. • Trunking the scanner to an active control channel while in Motorola mode will display the Motorola System. ID and the approximate control channel message decode success rate. This information can help you identify the Motorola Trunking system that you are monitoring and the receive quality of the control channel signal. 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 system 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-digit formats for talk group IDs. Note: If the scanner decodes control channel data while receiving transmissions from a Motorola trunking system, CNTRL appears on the bottom line of the display. EDACS mode You can set your scanner so it decodes the talk group IDs used with EDACS (GE/Ericsson) trunking systems. This setting is called the EDACS mode. EDACS systems are trunking systems 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 scanner to correctly switch to an active frequency, you must program the frequencies in LCN order, starting with Memory 01. EDACS talk group IDs are entered as a 4-digit decimal number from 0001 to 2047 or AFS (Agency Fleet Subfleet) number from 00-001 to 15-157. 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 with IDs that match talk group IDs you have stored in the bank’s talk group ID list which are not locked out. Because EDACS scanning requires 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 CTL-01. Try changing your location or using an outdoor antenna to improve reception.
20-428 Owner’s Manual Page 10 of 50 LTR mode You can set your scanner so it decodes the talk group IDs used with LTR (E.F. Johnson) systems. This setting is called the LTR mode. LTR frequencies are organized in a specific order. Each frequency is assigned a Home Repeater Number (HR). For the scanner to correctly switch to an active frequency, you must program the frequencies in HR order, starting with Memory X01 in the selected bank. Your PRO-2055 scanner features a new tool to help you determine the correct channel mapping for LTR system frequencies. The scanner’s LTR Repeater Finder displays the current Home Repeater when monitoring LTR transmissions in manual mode. To determine the correct Home Repeater programming, enter the system channels of an LTR system in any order. Be sure to program the mode for each LTR channel to LT. Listen to each channel one at a time in manual mode and watch for the decoded LTR data at the bottom of the scanner’s display. When an LTR transmission occurs, you should see the LTR talkgroup information on the bottom line of the display, and a number preceded by “R” in the bottom right hand corner (i.e., R12). The “R” number is the Home Repeater number that the current transmission is occurring on. To correctly program this Home Repeater number into your scanner, be sure that the channel number in the bank is equal to the number that is displayed after the “R”. For example, if you see R12 displayed on a particular LTR frequency, that frequency needs to be programmed into Channel 12 of the current bank in order to track the LTR system activity properly. LTR systems are trunking systems used primarily by business or private communications service providers, such as taxicabs, delivery trucks, and repair services. These 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 six-digit numbers. These numbers are 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. open and closed modes
20-428 Owner’s Manual Page 11 of 50 You can set your scanner to change the way it receives signals. These settings, called open mode and closed mode, affect how the scanner receives signals from communications systems that use some type of closed squelch (such as Motorola, EDACS, and LTR systems). Notes: • In open mode, you hear all active talk groups except those you specifically exclude, making it easy to hear everything going on. In closed mode, you hear only those talk groups you specify. This makes it easy to listen only to talk groups you are interested in and exclude others. • When you select a system voice channel manually, any transmission opens squelch, regardless of the current mode. • When no ID code is programmed into the scanner, it receives the signal in MO, ED, or LT mode. In open mode, the scanner stops on any transmission. If the ID is stored, the text tag appears on the display. Otherwise, the talk group ID appears on the display. In closed mode, the scanner only stops on a transmission if the ID is stored. You can set each of the scanner’s channel storage banks to open or closed mode. In open mode, the scanner scans signals transmitted in all systems. The scanner stops on any ID code and only uses the ID list to look up ID text tags. In closed mode, the scanner stops only on signals that have an ID code which is found in the ID list for the bank. Also, the scanner scans signals transmitted only under the following conditions: • When the signals are in the FM. CT, or DC mode. • When the signals are in the MO, ED, or LT mode and the signal’s ID code matches the programmed ID code. You can also select the user or talk groups you want the scanner to receive in closed mode. When you set a channel storage bank to open mode, + appears under the bank’s number while scanning. When you set a channel storage bank to closed mode, – appears under the channel storage bank’s number while scanning. OPEN or CLOSED appears while the scanner is in manual mode or while the scanner is receiving a signal during scanning. See “Changing the Open/Closed Mode” for more information about setting the open and closed modes. setting up your scanner turning on the scanner and setting squelch 1. To turn on the scanner, turn VOL clockwise. Multi-system Trunking Scanner appears. After about 3 seconds, you might hear a hissing sound. Then adjust VOL to a comfortable level.
20-428 Owner’s Manual Page 12 of 50 2. Turn SQ fully counterclockwise, then turn SQ clockwise until the hissing sound stops. 3. To turn off the scanner, turn VOL counterclockwise to OFF. Notes: • The scanner does not scan if there are no frequencies stored in channels. If the scanner does not scan and you have already stored frequencies in channels, turn SQ further clockwise. • If the scanner picks up unwanted, partial, or very weak transmissions, turn SQ clockwise to decrease the scanner’s sensitivity to these signals. If you want to listen to a weak or distant station, turn SQ counterclockwise. • If SQ is adjusted so you always hear a hissing sound, the scanner will not scan properly. • To ensure the scanner operates properly while in the trunking mode, we suggest you set SQ using the steps listed above. • If SQ is adjusted precisely at the threshold where the hissing sound stops, the radio will be most sensitive to very weak signals. The radio may also receive unwanted noise or signals that are too weak to understand. Most users prefer to position the squelch control a little bit past the point of threshold to avoid receiving noise or signals that are too weak to understand. storing known frequencies into channels Good references for active frequencies are RadioShack’s Police Call, Aeronautical Frequency Directory, and Maritime Frequency Directory. We update these directories every year, so be sure to get a current copy. Follow these steps to store frequencies into channels. Notes: . If you are storing frequencies for an EDACS system, you must store them in order, with the first frequency in channel 1 for the current bank. For example, if you want to store frequency of 150.0000, 150.0125, 150.0250, and 150.0375 MHz, you must store them in Channels 1, 2, 3, and 4 respectively. . When M appears on the display, you can use FUNC and the arrow keys to select your desired bank and channel number. 1. Press MAN, enter the bank (0-9) and channel number (00-99) where you want to store a frequency, then press MAN again. M and the bank and channel number appear at the upper left corner of the display (for example: M000). Notes: • Press FUNC. Then press /¥ or ¥/. The bank number moves in the direction of the arrow pressed. • Press FUNC. Then hold down /¥ or ¥/. The bank number moves continuously in the assigned direction. • Press /¥. The channel number moves upward one by one. Or, press ¥/. The channel number moves
20-428 Owner’s Manual Page 13 of 50 downward one by one. 2. Press PGM. M changes to P. 3. Use the number keys and •/DELAY to enter the frequency (including the decimal point) you want to store. If you make a mistake, press CLEAR to delete a single digit or press and hold CLEAR about 2 seconds to delete all digits. 4. Press ENT to store the frequency into the channel. Notes: • If you made a mistake in Step 3, Invalid Freq. briefly appears and the scanner beeps when you press ENT. Start again from Step 3. • Your scanner automatically rounds the entered frequency to the nearest valid frequency. For example, if you enter a frequency of 151.553, your scanner accepts it as 151.550. • All scanners tune by steps. Your RadioShack scanner uses steps consistent with the latest US or worldwide standards. If you enter a non-valid step frequency, any scanner will tune to the next step. Some scanner designs do this without showing the correct step in the display. This scanner will show the actual tuned frequency in the display. Because steps are so close together, the audio quality will not be affected by the offset. • After a transmission, the scanner automatically pauses for 2 seconds on this channel before proceeding to the next active transmission. Press •/DELAY to turn the delay function off or on. See “Using Delay”. The scanner stores this setting in the channel. 5. If necessary, press MODE to change the receiving mode. 6. If desired, program a text tag for the channel (see Assigning a Text Tag to a Channel”). 7. The next channel in sequence is ready for programming. Press PROG then repeat steps 3 through 6. CTCSS and DCS CTCSS and DCS allow you to program frequencies into your scanner that are used by more than one group in your area and listen only to the group that is of interest to you by specifying the group’s specific CTCSS or DCS code. CTCSS and DCS can also help reduce instances where interfering signals cause your scanner to stop on one channel. There are two ways you can program your scanner to operate with CTCSS and DCS. If you know the CTCSS or DCS code that is used on a particular frequency, you can manually enter the code when you are programming the scanner, or any time afterwards.
20-428 Owner’s Manual Page 14 of 50 You can also set a special search code up that will instantly decode the CTCSS or DCS code on a received transmission. Channels programmed with the search code will receive all traffic on the channel, and will instantly decode and display any CTCSS or DCS code that is found with the transmission. You can then store the found code in the channel memory with one keystroke. This section of the manual describes the process for configuring a memory channel for CTCSS or DCS operation and manually programming a known code. For more information on using the CTCSS and DCS feature while scanning, see “Using CTCSS and DCS”. To program channel memories for CTCSS or DCS operation, follow these steps: 1. First, enter a conventional frequency. See “Storing Known Frequencies into Channels”. 2. Once you have entered the frequency, press MODE until the desired mode appears in the upper left hand corner of the display. Use CT for CTCSS, and DC for DCS. 3. By default, the search code (indicated with Code Search in the bottom of the display) is programmed. To program a specific code, press FUNC, MODE, and then use the arrow keys to scroll to the desired CTCSS or DCS code. You can also use the keypad to enter the code manually. Note that the scanner will automatically fill the code field as you enter the code. 4. Once the desired code is selected, press ENT to store the code in the channel memory. 5. It is possible to program memory channels for CTCSS or DCS operation at any time. Simply place the scanner in program mode, navigate to the channel you wish to change, and follow the steps above. 6. When stopped on an active conventional channel while scanning, you can press MODE to cycle through the valid modes for that channel, including CTCSS and DCS. This will reset any stored CT or DC code to the search code, allowing you to easily check for other CT or DC codes that may be present on the frequency. Note: CTCSS, DCS and digital voice all operate independently of each other. If a channel is configured for CTCSS or DCS, it will not be able to decode digital transmissions. Use the FM mode when mixed analog and digital voice reception is desired.

Your scanner scans through the weather band then stops within a few seconds on the next available weather broadcast. SAME standby mode The National Weather Service precedes each weather alert with a digitally encoded SAME (Specific Area Message Encoding) signal, then a 1050 Hz tone. The SAME signal includes a FIPS (Federal Information Processing Standard) area code, and an event code that corresponds with the type of alert being sent. You can configure your scanner to operate in SAME Standby mode, where it monitors a selected weather radio station for SAME alerts for areas you specify. You can program your scanner with up to 10 FIPS codes for the areas you desire. The National Weather Service maintains a current list of FIPS codes at http://www.nws.noaa.gov/nwr/. To configure your scanner for SAME Standby mode, follow these steps: 1. Press WX until you identify the weather station with the strongest signal for your location. 2.

Skywarn Many areas of the country have amateur radio repeaters that have been designated as “Skywarn” repeaters. During times of severe weather, these repeaters are used to relay reports of severe weather directly to meteorologists at a local National Weather Service (NWS) forecast office. Using the Skywarn feature in your scanner, you can easily jump to one of three Skywarn repeater frequencies and monitor these reports, in many cases hearing about severe weather in your area instantly as it occurs. This function lets you quickly move to the skywarn channels (channels 997 through 999) from any mode except SAME standby by pressing and holding WX about 1 second. The scanner displays Skywarn-1 in the fourth line. The scanner has 3 Skywarn channels. Press /¥ or ¥/ to select different Skywarn channels. Note: To activate this function, you must program your desired Skywarn frequencies into the Skywarn channels. using frequency copy You can copy a frequency into a specified channel, a vacant channel in a specified bank, or a priority channel.

Press FUNC then PRI when the frequency appears. The display flashes twice and the frequency is copied to the priority channel. Signal Stalker II
20-428 Owner’s Manual Page 27 of 50 Your scanner’s Signal Stalker II feature provides a powerful new tool for you to rapidly detect, monitor and store frequencies for nearby radio transmissions. The Signal Stalker II feature is similar in functionality to portable frequency counters that cost much more than your scanner, but provides many advantages over typical portable frequency counters. For example: The Signal Stalker II allows you to sweep the entire range of your scanner’s design frequencies, or you can specify those frequency ranges that you wish to sweep and exclude ranges that you do not want to sweep. This allows you to omit frequency ranges with constant strong frequency activity, such as those with paging or broadcast transmitters. Many portable frequency counters will remain locked to a nearby constant signal, such as a paging or broadcast transmitter, and will not function properly until you have left the vicinity of the transmitter. The Signal Stalker II feature is more sensitive than portable frequency counters and will detect transmissions at a greater distance. You can activate the Attenuator to reduce the sensitivity if desired. Once an active frequency is found, the transmission is played through your scanner’s speaker, and you can quickly store it in any of your scanner’s memory locations. using Signal Stalker II Your scanner’s Signal Stalker II functions when you press and hold (stalker mark) for approximately 1 second. The Signal Stalker II function can be set to watch for activity on all band frequencies or Police/Fire frequencies only. To change the all bands to police/fire or vice versa, press FUNC then (stalker mark). You can also turn on/off frequency sub-bands using the corresponding number keys while Signal Stalker II is active. Note: Priority mode is not available while using the Signal Stalker II. Press FUNC then /¥ or ¥/, you can change the normal Signal Stalker II operation to the Special Signal Stalker II operation. In the Special Stalker operation, Sp. Stalker appears and the frequency range is divided by 1 MHz segment. If you lock out 5 frequencies within a 1 MHz segment, the scanner will skip that segment in subsequent sweeps. See “Using Signal Stalker II with Lockout” below. using Signal Stalker II with lockout The scanner’s lock out feature can be used to bypass unwanted transmissions while using the Signal Stalker II. Press L/OUT when the scanner is stopped on an undesired transmission. Press FUNC L/OUT to review or clear locked out frequencies in the Signal Stalker II. You can lock out 150
20-428 Owner’s Manual Page 28 of 50 frequencies while searching all bands and 50 frequencies while searching Police/Fire frequencies. Signal Stalker II functions by rapidly sweeping through the RF spectrum in 1 MHz segments. If RF signal energy is detected in a 1 MHz segment, Signal Stalker II will sweep through the 1MHz segment in finer steps until the source of the RF signal energy is found. Certain segments of RF spectrum are used by high power transmitters, such as paging transmitters. The Signal Stalker II can detect these transmitters easily, even at great distances due to their high transmitter output power. You can press L/OUT when the Signal Stalker II stops on these undesired transmissions to prevent the Signal Stalker II from stopping on them in future sweeps, however, the Signal Stalker II will still see their RF signal energy when sweeping through the 1 MHz segment. This will cause the Signal Stalker II to execute another fine step search of the 1 MHz segment. Of course, if you have locked out the undesired transmissions, the Signal Stalker II will not stop on them again, however, the overall sweep performance of the Signal Stalker II will be impacted. Signal Stalker II features a special lockout mode that causes the scanner to skip a 1 MHz segment if five or more lockouts exist in that 1 MHz segment. To activate this mode, press FUNC /¥ while in the Signal Stalker II mode. If a 1 MHz segment contains 5 or more lockouts it will be skipped entirely while Signal Stalker II is sweeping. Use FUNC L/O to review or clear locked Signal Stalker II frequencies. To clear a locked-out frequency, select that frequency, then press CLEAR. scanning the channels To begin scanning channels or to start scanning again after monitoring a specific channel, press SCAN. Notes: . You must store frequencies into channels before the scanner can scan them. The scanner does not scan through empty channels. . To change the scanning direction, press /¥ or ¥/. The scanner scans through all channels (except those you have locked out) in the active banks (see “Turning Channel-Storage Banks Off and On” and “Locking Out Channels or Frequencies”). turning channel-storage banks off and on To turn off banks while scanning, press the bank’s number key so the bank’s number disappears. For example, to turn off bank 1, press 1. The scanner does not scan any of the channels within the banks you turned off. To turn on banks while scanning, press the number key until the bank’s number appears. For
20-428 Owner’s Manual Page 29 of 50 example to turn bank 1 on again, press 1. Notes: • You cannot turn off all banks. There must be at least one active bank. •You can manually select any channel in a bank, even if the bank is turned off. monitoring a single channel/power save circuit You can monitor a single channel with your scanner by navigating to that channel while in manual mode. The scanner will receive traffic on the selected frequency. Your scanner features a power save circuit that is automatically activated any time you manually select a channel. The power save mode works by allowing the receiver to “sleep” briefly while waiting for a call on the selected channel. The power save circuit is disabled when the scanner is tuned to a channel in program mode. using CTCSS and DCS Your scanner’s advanced, CTCSS and DCS decoder allows you to listen only to the group that is of interest to you by specifying the group’s specific CTCSS or DCS code for a certain frequency. CTCSS and DCS can also help reduce instances where interfering signals cause your scanner to stop on one channel. When your scanner stops on a conventional frequency that is configured for CTCSS or DCS, it checks for a match between the transmitted and stored codes match, the scanner stops on the transmission and allows the audio to pass to the speaker. If the codes do not match, the scanner resumes scan operation. If the special “search” code is in use, the scanner will instantly display any detected CTCSS code if programmed for CTCSS mode, or DCS code if programmed for DCS code. You can store the detected code into the channel memory by pressing ENT while the code is displayed. For more information about your scanner’s receive modes, including CTCSS and DCS, see “Understanding Your Scanner’s Modes”. For more information on programming memory channels for CTCSS or DCS operation, see “CTCSS and DCS”. deleting frequencies from channels 1. Press MAN. 2.

With the priority feature, you can scan through programmed channels and still not miss an important or interesting transmission on a specific channel. When 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. Notes: • The priority feature does not operate while the scanner receives a trunking voice channel or during trunking delay time. Therefore, the priority check seems random during peak hours. • If you program a weather channel as the priority channel, the scanner stays in the priority channel only when the scanner detects the weather alert tone. • This scanner cannot set a channel as the priority channel if the channel’s receive mode is MOT, ED, or LTR. • If you press PAUSE while the scanner receives the priority channel, the scanner displays *** PAUSED *** and stays on the priority channel even after the transmission finished. To program a frequency in the priority channel: 1. Press MAN. 2. Use the number keys to enter the channel number which contains the frequency you want to program as the priority channel. Then press MAN again. 3. Press FUNC then PRI. The display blinks. To program the priority channel directly: 1. Press PROG. 2. Press PRI. 3.

Or if the scanner detects a weather alert tone in Priority WX mode, Priority Channel! appears for 3 seconds then changes to Weather ALERT and the scanner sounds an alert tone. Notes: • Priority WX is only for receiving a weather alert. • When the scanner detects a 1050 Hz alert tone, priority WX activates and you receive a weather alert. • If you program a weather frequency into the priority channel and the scanner detects a weather alert tone on that frequency, the scanner sounds the alert tone. To turn off the priority feature, press PRI. 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 trunking transmissions in closed mode, you might have to change the receive mode. To change the receive mode, repeatedly press MODE. The receive mode changes as follows: AM – accesses the AM mode FM – accesses the FM mode CT – accesses the FM mode, CTCSS System DC – accesses the FM mode, DCS System MO – accesses the FM Mode, Motorola Trunking System (with 4- or 5-digit ID code) ED – accesses the FM Mode, EDACS Trunking System (with 4-digit decimal ID code or 5-digit AFS code) LT – accesses the FM mode, LTR Trunking System (with 6- digit ID code)
20-428 Owner’s Manual Page 34 of 50 Note: MO (MOT), ED, and LT modes are not available when the scanner tunes up or down through the frequency ranges in which the trunking operation is not used. using the attenuator To reduce interference or noise caused by strong signals, you can reduce the scanner’s sensitivity to these signals. There are two attenuator modes in your scanner. One is normal attenuator mode in which you set the attenuator in each channel or each band/group in the search and tune mode. The other is global mode in which you set the attenuator only once. This setting is applied all the time in every mode. Press ATT to turn on or off the attenuator while the channel number is indicated or while the scanner is searching through bands/groups. When the attenuator is on, att changes to ATT. When you turn it off, ATT changes to att. You cannot set the attenuator while the scanner is scanning. Press FUNC and then ATT to set the attenuator to its global mode. Global ATT. appears for 2 seconds at the bottom line and atg appears. Press ATT to turn the attenuator on or off. ATG or atg appears on the second line. Press FUNC and then ATT again to turn off the global attenuation mode. Normal ATT. appears on the bottom line for about 2 seconds.

Confirm to send data? 1 –> YES Press other key for NO. appears. 4. Press 1 to send the data to the other unit or press any other key to cancel the operation. The scanner sends the data. To exit the clone mode, remove the cable. Trunking how trunking works The 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 extensively used in many communication systems. 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.
20-428 Owner’s Manual Page 36 of 50 To receive trunking signals, you must store all the trunking control frequencies for Motorola systems or all the trunking group frequencies for EDACS and LTR in one bank (see “Storing Known Frequencies into Channels”) and input ID codes in the ID memory (see “Storing Talk Group IDs”). Your PRO-2055 automatically calculates Motorola voice channel frequencies when it decodes the control channel. This eliminates the need to enter all the Motorola group frequencies. The control channels are subject to change depending on the day. Therefore enter all the control frequencies in the same bank. If you do not know which is the control channel, it is better to enter all the system frequencies into the same bank. When the scanner decodes the Motorola control channel and finds the voice channel, the scanner displays the control channel memory location on the top line, the received frequency with VC (voice channel) on the second line, the bank and control channel memory location number on the third line and the Motorola ID number on the bottom line. Note: To listen to the transmission, the mode of the programmed channel must be the same as that of the trunking channel (MO, ED, or LT). When an ID code is received, the ID list for the bank is searched, and if found, the text name stored for the ID appears. If not found, scanning resumes immediately unless the bank is in open trunking mode. Notes: •There might be more than one talk group transmitting at a time in some Motorola trunking systems. If you set the scanner to manually tune in Motorola trunking mode, you will hear the talk group on that channel, but the display will alternate between all active IDs. • Frequency fleet map and talk group information are also widely available on the Internet (for example, at www.trunkscanner.com). In the past, groups that transmit frequently, such as police departments, could transmit on only 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 transmits. 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. Your scanner lets you easily hear both the call and response transmissions for that 2-way radio user and therefore follow the conversation. For EDACS and Motorola (above 406 MHz range), the scanner monitors the control channel between each transmission to identify talk groups. For some Motorola (under 512 MHz range) and LTR systems, the scanner uses the subaudible data sent with
20-428 Owner’s Manual Page 37 of 50 each transmission to identify talk groups. setting squelch for trunking mode Your scanner automatically mutes the audio during trunk scanning when it decodes control channel data. However, we recommend you turn SQ clockwise and leave it set to a point just after the rushing sound stops. This lets the scanner quickly acquire the data channel. programming trunking frequencies You program trunking frequencies the same as non-trunked frequencies, except that you must store the appropriate mode (MO, ED, or LT) with each frequency. Notes: • You can scan only one type of trunked frequency, either EDACS, Motorola, or LTR in a bank at one time. You can, however, mix conventional channels and frequencies in a bank. • If you are programming trunked frequencies for Motorola Type I and hybrid systems, you must first program the fleet map (see “Programming Fleet Maps”). • If you are programming frequencies for an EDACS system you must store them in the Logical Channel Number order (usually listed as LCN#). For example, LCN1 would go into channel 01 for the current bank, and LCN2 would go into channel 02. • If you are programming frequencies for an LTR system you must store them in the home repeater order. For example, home repeater order 1 would go into channel 01 for the current bank, and home repeater order 2 would go into channel 02. Follow these steps to program trunked frequencies: 1. Press PROG and select the bank. Note: To move through the bank selection faster, press PROG then FUNC and hold down /¥ or ¥/. To move through the banks one at a time, repeat the sequence of PROG, FUNC then /¥ or ¥/ until you reach the desired bank. 2. Press TRUNK to enter the ID program mode. 3. Repeatedly press MODE to select Motorola, EDACS (GE/Ericsson), or LTR (EF Johnson) system to scan. This sets the talk group ID decoding method to be used for the bank. Note: If you select conventional mode instead of Motorola, EDACS, or LTR, the scanner does not scan trunked frequencies. Trunking mode not selected, press Mode key. appears. 4. Press PROG to enter the program mode.
20-428 Owner’s Manual Page 38 of 50 5. Enter the desired trunking frequency then press ENT to store. 6. To enter additional trunking frequencies as subsequent channels in the same bank, press PROG or /¥ to access the next open channel then enter the frequencies. (See “Storing Known Frequencies into Channels”). 7. Press SCAN to start scanning. Notes: • If you enter a frequency that has already been entered, the scanner sounds an error tone and displays Dupl. Freq. and the channel number that has been duplicated. If the dual entry is an error press CLEAR and enter the correct frequency. If the dual entry is intentional press ENT to accept. • You may replace any frequency by selecting the bank and channel, pressing PROG and entering the new frequency. If you make an error in the entry process, press CLEAR as often as needed to erase the incorrect data. programming Motorola trunking systems (UHF-Lo) You can program the scanner to receive transmissions in the UHF-Lo band (406-512 MHz) of the Motorola Trunking system. You can receive these transmissions by checking the trunking system’s control channel. You must program the system’s base frequency and offset frequency to do this. Note: Base and offset frequencies vary for each type of trunking system. You can get information about these frequencies for the trunking system you want to scan using www.trunkscanner.com, other Internet sources, or locally published guidebooks. If you try to program an offset frequency in the UHF-Hi bands (806-960 MHz), the scanner ignores the entry. Follow these steps to program Motorola trunking frequencies in the UHF-Lo band: 1. Press PROG then TRUNK to enter the ID program mode. 2. Press FUNC and press (or hold) /¥ or ¥/ to select the bank. 3. Press MODE and select MOT. 4. Press FUNC then 2. The display indicates Custom Range 1/3 on first line. Base: 406.0000 on the second line, Offset: 380 on the third line and Step:25kHz on the bottom line. 5.

20-428 Owner’s Manual Page 41 of 50 There are 10 talk group ID banks and each ID bank has 5 sub-banks. Each sub-bank has 30 ID locations. You can program up to 150 talk group IDs in each bank, so you can program up to 1,500 talk group IDs in 10 banks. When the scanner stops on a transmission in the Motorola, EDACS, or LTR mode, it checks to see if the ID has been stored. In the closed mode, the scanner only stops on the transmission and displays its text tag if you have stored and not locked out the ID. In the open mode, the scanner always stops on a transmission, but it displays the ID’s text tag if you have stored the ID. storing talk group IDs To store a talk group ID, press TRUNK when the scanner stops on a voice channel transmission or when a talk group ID is indicated in the manual mode.

20-428 Owner’s Manual Page 45 of 50 care Keep the scanner dry; if it gets wet, wipe it dry immediately. Use and store the scanner only in normal temperature environments. Handle the scanner carefully; do not drop it. Keep the scanner away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new. replacing the fuse First, turn off the scanner and your vehicle’s ignition. Make sure you replace the fuse only with another fuse of the same type and rating (2-amp, fast-acting glass fuse). service and repair If your scanner is not performing as it should, take it to your local RadioShack store for assistance. To locate your nearest RadioShack, use the store locator feature on RadioShack’s website (www.radioshack.com), or call 1-800-The Shack (800-843-7422) and follow the menu options. Modifying or tampering with the scanner’s internal components can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate it. 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 frequencies, you hear only noise on that frequency. If the interference is not severe, you might be able to turn SQ clockwise to omit the birdie. To find the birdies in your scanner, begin by disconnecting the antenna and moving it away from the scanner. Make sure that no other nearby radio or TV sets are turned on near the scanner. Use the search function and scan every frequency range from its lowest frequency to the highest. Occasionally, the searching will stop as if it had found a signal, often without any sound. This is a birdie.

Specifications and depictions are subject to change and improvement without notice. resetting/initializing your scanner If the scanner’s display locks up or does not work properly after you connect a power source, you might need to reset or initialize it. If you have problems with the scanner, first try resetting it, which will retain items stored in memory. If that does not work, initialize the scanner. You may be able to save the information in your scanner’s memory to your computer, or another scanner before initializing it. See “Cloning the Programmed Data”. resetting your scanner 1. Trun off your scanner, and then turn it on again. 2. Insert a pointed object into the reset hole on the back of the scanner. Then, gently press and release the reset button. Pressing reset does not clear the scanner’s working memory of the V-Scanner folders. initializing your scanner Initializing your scanner clears all information stored in your scanner’s working memory. Initialize your scanner only when you are sure it is not working properly. 1. Turn off the scanner, then turn it on again. Multi-system Trunking Scanner appears. 2. Press 0 while Multi-system Trunking Scanner appears.

The FCC wants you to know This equipment has been tested and found to comply with the limits for a scanning receiver, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. scanning legally Your scanner covers frequencies used by many different groups including police and fire departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wireline (telephone and telegraph) service providers. It is legal to listen to almost every transmission your scanner can receive. However, there are some transmissions you should never intentionally listen to. These include: • Telephone conversations (cellular, cordless, or other private means of telephone signal transmission) • Pager transmissions • Any scrambled or encrypted transmissions According to the Electronic Communications Privacy Act (ECPA), you are subject to fines and possible imprisonment for intentionally listening to, using, or divulging the contents of such a transmission unless you have the consent of a party to the communication (unless such activity is otherwise illegal).
20-428 Owner’s Manual Page 49 of 50 This scanner has been designed to prevent reception of illegal transmissions. This is done to comply with the legal requirement that scanners be manufactured so as to not be easily modifiable to pick up those transmissions. Do not open your scanner’s case to make any modifications that could allow it to pick up transmissions that are illegal to monitor. Doing so could subject you to legal penalties. In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area. It is also illegal in many areas to interfere with the duties of public safety officials by traveling to the scene of an incident without authorization. We encourage responsible, safe and legal scanner use. glossary Frequency – the receiving signal location (expressed in MHz). To find active frequencies, you can use frequency guides available from your local RadioShack store, frequency listings posted on the Internet, or the built-in search function. Channels – programmable memory locations for the frequencies you want to monitor. Each time the scanner finds an active frequency, it stops and monitors the radio traffic on that channel until the transmission ends, then resumes scanning. Channel Storage Banks – a storage area for a group of channels. Channels are storage areas for frequencies. Whereas a channel can only contain one frequency, a bank can hold numerous channels. Search Banks – contain preprogrammed frequencies in the scanner’s memory. Your scanner has six preprogrammed search banks configured to search various radio services, and one limit search bank that you can configure. You can set the lower and higher frequency limit in the limit search bank. For example, if you wanted to find active frequencies between a range of 150.1000 and 150.5000, you would put both of those frequencies in the limit search bank. You can even change the frequency range in a search bank (SR6) to customize your search parameters. Talkgroup IDs – each channel storage bank has an associated talkgroup ID list, for a total of 10 talkgroup ID lists. Each ID list has 5 sub-banks. Each sub-bank has 30 ID locations. You can program up to 150 talkgroup IDs in each bank, so you can program up to 1500 talkgroup IDs in 10 banks. When the scanner stops on a transmission in the Motorola or EDACS mode, it checks to see if the ID has been stored in the associated ID list. In the Closed Mode, the scanner only stops on the transmission and displays its text tag if you have stored and not locked out the ID. In the Open Mode, the scanner always stops on all transmissions except those you specifically exclude, and displays the ID’s text tag if you have stored the ID. For a detailed description of Open and Closed Mode operation, see “Open and Closed Mode Operation”.
20-428 Owner’s Manual Page 50 of 50 FAQs (Frequently Asked Questions) The scanner is not working at all. What’s wrong? The AC or DC adapter or DC cable might not be connected. Be sure the adapter/cable’s barrel plug is fully inserted into the PWR DC 13.8V jack. The center tip of the adapter/cable’s barrel plug must be set to positive. The scanner does not receive any stations or reception is poor. What’s wrong? The scanner might need to reset or initialize. Insert a pointed object into the reset hole on the back of the scanner, or initialize the scanner (see “Initializing the Scanner”). The scanner is on but does not scan. What’s wrong? The squelch might not be adjusted correctly. Turn SQ clockwise. There might only be one channel or no channels stored in the scanner. Store frequencies into more than one channel. While scanning, the scanner locks on frequencies that have an unclear transmission. What’s wrong? Some frequencies programmed into the scanner might be the same as “birdie” frequencies. Avoid programming “Birdie Frequencies” or only listen to them manually. limited one-year warranty Printed in Hong Kong GE-05D-0620 05A05 R/S address
