The Basics step 1: install your scanner You can mount your 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.
The Basics Note 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.
The Basics 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. 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. When drilling holes, be sure to avoid obstructions Note behind the mounting surface.
The Basics step 2: 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 1. Connect the tip of the supplied AC adapter to the DC 13.8V jack at the rear of your scanner. Note 2. Plug the AC adapter into your wall outlet. 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.
The Basics 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. Be sure the grounding Note screw makes complete contact with the metal frame of your vehicle. 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.
The Basics from your vehicle’s cigarrette lighter To power your scanner from a 12V power source in your vehicle, such as a cigarette-lighter socket, you need a 12V, 600 mA 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.
The Basics step 3: connect your scanner 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.
The Basics 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.
The Basics 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.
The Basics 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. 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”.
The Basics 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.
The Basics 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. DCS mode also features a Code Search setting that allows you to instantly display and store unknown codes into the channel memory.
The Basics 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.
The Basics 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.
The Basics 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.
The Basics 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 Basics 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 You can set your scanner to change the way it receives signals.
The Basics 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.
The Basics setting up your scanner turning on the scanner and setting squelch 1. To turn on the scanner, turn VOL clockwise. Multisystem Trunking Scanner appears. After about 3 seconds, you might hear a hissing sound. Then adjust VOL to a comfortable level. 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. The scanner does not scan if there are no Note frequencies stored in channels.
The Basics 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.
The Basics Note Press FUNC. Then press e or d. The bank number moves in the direction of the arrow pressed. Press FUNC. Then hold down e or d. The bank number moves continuously in the assigned direction. Press e. The channel number moves upward one by one. Or, press d. The channel number moves downward one by one. 2. Press PROG. M changes to P. 3. Use the number keys and ./DELAY to enter the frequency (including the decimal point) you want to store.
The Basics 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.
Beyond the Basics 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”.
Beyond the Basics 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. CTCSS, DCS and digital voice all operate Note independently of each other.

Beyond the Basics 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.
Beyond the Basics 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.
Beyond the Basics 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 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.

Beyond the Basics glossary Frequency — the receving 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.
Beyond the Basics 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 diplays the ID’s text tag if you have stored the ID.
Beyond the Basics 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 be reset or initialized.
