install your scanner

You can mount your 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.

20-427 Owner’s Manual Draft

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.

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.

20-427 Owner’s Manual Draft

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.

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

28–54 MHz Extend fully

108–174 MHz Extend 4 segments

406-960 MHz Collapse fully

connect an external antenna

You will need to connect an external antenna when you mount your scanner in the

dashboard of 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

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 three features before you begin programming the scanner.

Signal Stalker II – searches nearby strong signals quickly. See “Signal Stalker II”.

One-Touch 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 the One

Touch Banks”.

Page 8 of 36

20-427 Owner’s Manual Draft

Manual Tuning – allows you to manually move through the entire range of available

frequencies. (See “Specifications” for a list of the available frequency Ranges.)

understanding channel storage banks

Abank is 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.

To make it easier to identify and select the channels you want to listen to, your scanner

divides the channels into 10 banks (1 to 10) of 30 channels each, a total of 300 channels. You

can use each channel-storage bank to group frequencies.

Note: The scanner is preset so each banks is turned on (see “Turning Channel-Storage

Banks Off and On”).

setting up your scanner

turning on the scanner and setting squelch

1. To turn on the scanner, turn VOL clockwise. WELCOME 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.

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

Page 9 of 36

20-427 Owner’s Manual Draft

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.

•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.

Note: When MAN appears on the display, you can use FUNC and the arrow keys to select

your desired bank and channel number.

1. Press MAN, channel number (1-300) where you want to store a frequency, then press

MAN again. MAN and the channel number appear at the display.

Notes:

•Press FUNC. Then press /¥ or ¥/. The bank moves in the direction of the arrow pressed.

•Press FUNC. Then hold down /¥ or ¥/. The bank moves continuously in the assigned

direction.

•Press /¥. The channel number moves upward one by one. Or, press ¥/. The channel

number moves downward one by one.

•Hold down /¥ or ¥/. The channel moves continuously in the assigned direction.

2. Press PROG. MAN changes to PGM.
