Be careful not to drill into anything behind the mounting surface.

Thank you for purchasing a RadioShack 40 Channel Mobile CB. Your CB is a great way to communicate with other CB radio operators. You can mount it in a vehicle for mobile use, or in your home for use as a base station.

To use this CB, you must connect a mobile or base station antenna. Your local RadioShack store has a wide variety of antennas. For more information, see “Connecting an Antenna” on Page 3.

You can attach the microphone holder to the right side of the transceiver or to another location in your vehicle.

To attach the holder to the transceiver, secure the holder to the right side using the sup pli ed 3 m m mac hin e sc rew s and lock washer.

To attach the holder to another location in the vehicle, such as the dashboard, follow these steps.

1. Using the holder as a template, mark the positions for the mounting screw holes at the desired location.

2. At each marked position, drill a small

starter hole.

Mounting the Transceiver

"9#40+0)

• If you use the CB in a vehicle, mount it securely to avoid damage to the CB or vehicle or injury to anyone in the vehicle during sudden starts or stops.

• Do not mount the CB where it could damage or interfere with the operation of any passive restraint safety device (an airbag or seat belt).

Be careful not to drill into anything behind the mounting surface.

3. Attach the holder at the mounting location using the supplied machine screws, spring washers, plain washers, and nuts.

The most common mounting location for this CB is under a vehicle’s dashboard. However, if you plan to use the CB as a base station, you can place it on a desk, shelf, or table (see “Using the Transceiver as a Base Station” on Page 6).

If you are mounting the CB in a vehicle, choose a location where:

Rý

• You can easily reach the CB.

• Wires and cables are clear of the vehicle’s pedals or other moving parts.

• The CB is not directly in front of heating vents.

• All wires and cables can reach their connection points.

Follow these steps to mount the CB using the supplied hardware.

1. Using the mounting bracket as a template, mark the positions for the screw holes on the mounting surface.

2. In each marked location, drill a small starter hole.

If you cannot reach behind the mounting surface to attach the nuts on the bolts or machine screws, use the supplied plain washers and self-tapping screws.

3. Mount the bracket to the mounting su rface with the supplied 5 mm bolts, spring washers, plain washers, and nuts.

4. Peel the backings off the adhesive on the back of the supplied rubber washers and attach the washers to the mounting holes on the C B. Then attach the CB to the mounting bracket using the mounting knobs.

There are many different types of CB antennas for mobile CBs. Each type has i ts own b enefits, s o choose the one th at best meets your ne eds. Yo ur loca l RadioSh ack s tore se lls a wide variety of antennas.

When you choose an antenna, keep in mind that, for the

best performance, you should mount the antenna:

• as high as possible on the vehicle

• as far as possible from sources of electrical noise

• vertically

Once you choose an antenna, follow its mounting instructions. Then route the cable to the transceiver and connect the cable to the transceiver.

• Avoid routing the cable next to sharp edges or moving parts, which might damage the cable.

• Do not run the cable next to power cables or other radio antenna cables.

• Do not run the cable through the engine compartment or other areas that produce extreme heat.

If you are using this CB as a base station, see “Using the Transceiver as a Base Station” on Page 6.

Connecting an Antenna

To take advantage of your radio’s maximum range, adjust the antenna’s Standing Wave Ratio (SWR) using an SWR meter (not supplied).

Follow the instructions supplied with the SWR meter and antenna to adjust your antenna’s SWR to the lowest possible value. SWR values of 2.0:1 are generally acceptable, with readings of 1.5:1 or lower being more desirable.

Never pull on the microphone cable.

Connecting the Microphone

%100'%6+0)"6*'" /+%412*10'

1. Align the tab on the side of the supplied microphone’s plug with the notch in the microphon e jack (on the side of the transceiver). Then insert the plug into the jack.

2. Slide the microphone onto the microphone holder.

3. To disconnect the microphone from the transceiver, press the tab on the side of the plug. Then pull out the

plug.

You can connect your transceiver to an external CB speaker, so you can hear an incoming call when you are outside your vehicle, or use the CB as a PA system.

The external speaker you use with the transceiver should have an impedance of 8 ohms and be able to handle 10 watts of power. The speaker cable must hav e a 1/8-inch plug.

"016'"±"

• When you connect an external speaker, the CB’s internal speaker disconnects.

• To avoid acoustic feedback, the speaker should be at least 6 feet from the CB. If you experience feedback, avoid keying the microphone until you have moved the speaker away from the CB.

To connect the external speaker to the transceiver, insert the speaker cable’s plug into CB.

Do not use an earphone with your transceiver when operating a motor vehicle in or near traffic. Doing so can create a traffic hazard and could be illegal in some areas.

If you use an earphone with your transceiver be very careful. Do not listen to a continuous broadcast. Even though some earphones/headphones let you hear some outside sounds when li stening at norma l volume level s, they still can present a traffic hazard.

• Do not connect the black wire to a non-metallic (plastic) part, or to any part insulated from the vehicle’s chassis by a nonmetallic part.

• Most 13.8-volt DC power supplies plug into a standard AC outlet to produce DC power. Before connecting your CB to a

13.8-volt DC power supply, read and follow the instructions included with the power supply.

• To prevent damage to the CB, be sure you connect an antenna and the microphone before you use your CB.
