Mobile CB with Compass, Dual Watch and Digital Weather Alert
Your RadioShack 40-Channel Mobile CB Radio provides two-way communications on the citizen’s radio band and lets you tune to local and national weather service broadcasts. You can also connect optional equipment to your CB such as external speakers, or a DC power supply and base antenna to set up a base station in your home. The builtin 40-channel PLL (phase-locked loop) frequency synthesizer uses a precise frequency reference crystal for reliable and exact tuning.
Ideal for recreational, business, or emergency use, your CB has these features:
Electronic Compass — provides accurate heading information.
Dual Watch — checks one channel while receiving another channel so you do not miss important transmissions. Dual Watch defaults to channel 9 (emergency call channel).
NOAA (National Oceanic and Atmospheric Administration) 7-Channel WX Band Receiver — lets you tune to seven national weather service frequencies which provide local weather conditions and forecasts.
WX Channel Autoscan — In CB mode, when a weather station carrier is lost, the CB automatically scans weather channels so it can detect a weather alert signal transmitted with a weather signal.
WX/Signal Indicator — shows the CB is ready to receive and indicates the reception of a weather alert.
Digital Weather Alert — uses Specific Area Message Encoding (SAME) digital information to determine and display the level of
weather events (does not limit alerts to a specific area).
ACE (Audio Clarity Enhancer) — suppresses noise levels while leaving the signal intact during reception. It enhances the transmission and provides a significant reduction in transmission and reception noise.
RF Gain Control — prevents overloading due to strong RF signals.
Convenient On-Microphone Channel Up/ Down Controls — let you quickly scan the band for communications.
Universal Mounting Bracket — lets you mount your CB securely in your vehicle.
Specialized Squelch Circuit — compensates for fading signals and eliminates signal chopping during reception.
Maximum Allowable Legal Power Output
— gives you the greatest available range.
TX Indicator — lights to show when the radio is transmitting.
Digital Channel Display — makes the channel number easy to see.
External Speaker Jack — lets you connect your CB to an external speaker.
Screw-On Mic Connector — ensures a secure microphone connection.
To use this CB, you need 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.

THE FCC WANTS YOU TO KNOW
The Federal Communications Commission (FCC) does not require you to have a license to operate this CB. However, the FCC does require that you read and know Part 95 of FCC Rules. These rules apply to the operation of a Class D CB. We have provided a copy of these regulations with your CB.
Warning: Do not open your CB to make any internal adjustments. Any internal adjustments can be made only by an authorized service technician.
Unauthorized internal adjustments and/or modifications can lead to illegal operation as defined by Part 95 of FCC rules. Such illegal operation can lead to very serious consequences.
Your CB might cause TV or radio interference even when it is operating properly. To determine whether your CB is causing the interference, turn off your CB. If the interference goes away, your CB is causing it. Try to eliminate the interference by either moving your CB away from the receiver or contacting your local RadioShack store for help. If you cannot eliminate the interference, the FCC requires that you stop using your CB.
If you cannot eliminate the interference, contact your local RadioShack store for help.
INSTALLATION
Attaching the Microphone Holder
You can connect the microphone holder to either side of the CB or to another location in your vehicle. To attach the holder to either side of the CB, horizontally or vertically, se-
cure it using the supplied small screws and lock washers.
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 for the supplied mounting screws.
Caution: Be careful not to drill into anything behind the mounting surface.
3.Attach the holder at the mounting location using the supplied small screws and lock washers.
Mounting the CB
The most common mounting location for this CB is under a vehicle’s dashboard. However, if you use the CB as a base station, you can place it on a desk, shelf, or table (see “Using the CB As a Base Station” on Page 4).
If you are mounting the CB in a vehicle, choose a location where:
•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.
2
•the magnetic fields caused by the vehicle’s wiring do not affect the CB. (See “Calibrating the Electronic Compass” on Page 8.)
•all wires and cables can reach their connection points.
Warning: 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.
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 position, drill a small starter hole for the supplied mounting screws.
Caution: Be careful not to drill into objects behind the mounting surface.
3.Attach the mounting bracket to the mounting surface with the supplied screws and lock washers.
4.Attach the CB to the mounting bracket using the supplied rubber washers and mounting knobs.
Note: To use the radio’s compass mode correctly, you have to install the CB horizontally.
Connecting the Microphone
1.Align the slot on the top of the microphone’s plug with the ridge inside the microphone jack. Then fully insert the plug into the jack.
2.Turn the plug’s locking nut clockwise to tighten it.
3.Slide the microphone onto the microphone holder.
To disconnect the microphone from the CB, unscrew the locking nut then pull out the plug.
Caution: Never pull on the microphone’s cable.
Connecting an Antenna
There are many different types of CB antenna for mobile CBs. Each antenna type has its own benefits, so choose the one that best meets your needs. Your local RadioShack store sells a wide variety of antennas.
For the best performance you should mount the antenna:
• as high as possible on the vehicle
