AAO210170640-Channel Citizen Band Transceiver

Owner’s ManualPlease read before using this equipment. 40 Channel Mobile CB with Digital Compass, and EL Backlit LCD Display 21-1706.fm Page 1 Wednesday, January 9, 2002 8:37 AM 2 Features à Features Your RadioShack 40 Channel Mobile 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. Your CB has these advanced features: LCD display with EL backlight on display and controls — lets you see the CB’s operating status at a glance and helps you easily see the display and controls when you use the CB at night. Digital Compass — aids navigation on the road. Emergency Channel One Touch Access — lets you quickly switch to Channel 9 or 19 so you can monitor or report emergency situations. 3 Channel Memories — let you easily access your favorite channels. Last Channel Recall (RCL) — Lets you quickly recall the last channel used. Dual Channel Controls — let you tune the channel from the transceiver or the microphone. RF Gain Control — lets you adjust the receiver’s gain to match the strength of the signal. Phase-Locked Loop (PLL) Frequency Synthesizer — provides highly accurate and stable tuning. Two Built-In Ceramic Filters — ensure superior channel selectivity and freedom from adjacent channel interference. Automatic Modulation Control — prevents the transmitter signal from over-modulating and distorting. Automatic Noise Limiter — reduces impulse-type noises while receiving. Built-In PA (Public Address) Amplifier — lets you use your CB as a public address system when you add an optional PA speaker. Universal Mounting Bracket — lets you mount your CB securely in your vehicle. Note: 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 4. FCC INFORMATION The Federal Communications Commission (FCC) does not require you to have a license to operate this CB radio. However, you must know Part 95 of FCC Rules. It explains the proper operation of a Class D citizen’s band transceiver. We enclosed a copy of Part 95 with your CB radio. Warning: Do not open the CB radio to make any internal adjustments. A CB radio is set up to transmit a regulated signal on an assigned frequency. It is against the law to alter or adjust the settings inside the unit to exceed these limitations. To be safe and sure: • Never open your CB radio’s case. • Never change or replace anything in your CB radio. © 2002 RadioShack Corporation. All Rights Reserved.

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: • moving your CB away from the receiver • contacting your local RadioShack store for help This device complies with Part 15 of the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. à Installation ATTACHING THE MICROPHONE HOLDER 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 supplied 3 mm screws 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. Caution: 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. Note: If you cannot reach behind the mounting surface to attach the nuts on the machine screws, use the supplied 3 mm plain washers and self-tapping screws. MOUNTING THE TRANSCEIVER 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: • You can easily reach the CB. • Wires and cables are clear of the vehicle’s pedals or other moving parts. 21-1706.fm Page 3 Wednesday, January 9, 2002 8:37 AM 4 Installation • The CB is not directly in front of heating vents. • All wires and cables can reach their connection points. Warnings: • 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). 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. Caution: Be careful not to drill into objects behind the mounting surface. 3. Mount the bracket to the mounting surface with the supplied 5 mm bolts, spring washers, plain washers, and nuts. Note: If you cannot reach behind the mounting surface to attach the nuts on the bolts, use the supplied 5 mm self- tapping screws and plain washers to secure the bracket. 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 CB. then attach the CB to the mounting bracket using the mounting knobs. CONNECTING AN ANTENNA There are many different types of CB antennas…
