Powering Your CB Radio You can power your CB radio from one of these four sources: • The rechargeable Ni-MH battery pack • Eight AA batteries (not included) using the supplied battery case • AC power using an AC-to-DC power supply (not included) • Vehicle power using a DC power cord (not included) Using the Ni-MH Battery Pack Charge the Ni-MH battery pack (using the supplied AC charger) for about 18 hours prior to using it for the first time.
• • • • • the AC charger to a ceiling outlet. After charging, disconnect the AC charger. You must use a Class 2 power supply that provides 16V DC and delivers at least 200mA. The barrel plug’s center must be positive and the barrel plug must fit the CB’s CHG jack. The supplied AC charger meets these specifications. Using an adapter that does not meet these specifications could damage the CB radio or adapter.
the polarity marks (+ and –). Snap the halves of the case together to close it. 3. Slide the battery case onto the CB radio until it clicks. The battery case fits onto the CB radio only one way.

Using Vehicle Power To power your CB radio from your vehicle, you will need a DC power cord (not included). You may also need a roof-mounted antenna to improve transmission quality and increase the transmission range.
Connecting Your CB Radio Installing the Antenna To install the supplied antenna, align the two slots on the antenna connector with the tabs on the BNC connector of the CB radio. Push the antenna connector to the CB radio and rotate the antenna connector clockwise until it locks into place. Installing an Optional Antenna The CB’s BNC connector allows you to use a variety of optional antennas, including external mobile antennas and outdoor base station antennas.
Operating Your CB Radio Receiving 1. Turn SQUELCH fully anticlockwise. 2. Turn on the CB radio. A channel number and the signal meter appear. If necessary, press CB/WX so that a channel number and the signal meter appear. 3. Press ▲ or ▼ to select the desired channel. 4. Adjust OFF/VOLUME to the desired volume level. 5. Slowly turn SQUELCH back clockwise just until the noise stops. Note: Do not turn SQUELCH too far clockwise because you might cut out weak signals.
Safety Precaution Your wireless hand-held portable transceiver contains a low power transmitter. When the Push-to-Talk (PTT) button is pushed it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices.
Key Lock To activate key lock, press and hold LOCK for 2 seconds. appears. This locks all keys except PTT and LIGHT. To unlock key control, press and hold LOCK for 2 seconds again. 6 Power Save If you do not press any key or if the CB radio does not receive any signal for about 10 seconds, the CB radio automatically enters power save mode. P. SAVE flashes. Scanning Channels 1. Press CB/WX to select the CB or weather mode. 2. Press and hold CH9/19 SCAN for 2 seconds.
Listening to the Weather Band The FCC has allocated channels for use by National Oceanic and Atmospheric Administration (NOAA). Regulatory agencies in other countries have also allocated channels for use by their weather reporting authorities. NOAA and your local weather reporting authority broadcast your local forecast and regional weather information on one or more of these channels. Listening to a Weather Channel Press CB/WX to select weather mode. WX appears.
Understanding Digital Weather Alert The weather service precedes each weather alert with a digitallyencoded SAME (Specific Area Message Encoding) signal, then a 1050 Hz tone. When your local weather station broadcasts a weather alert signal, the CB radio sounds an alert tone and displays a message showing the alert level.
Additional Information Legal Use of Your CB Radio The CB Radio service is a private, two-way, short-distance voice communications service for personal or business activities. For rules regarding legal CB radio use, see the included Plain English Rules – Citizens Band Radio Service published by the FCC. Common Uses for a CB Radio • Warn of traffic tie-ups ahead. • Help truck drivers and delivery personnel learn road and traffic conditions and get assistance in locating destinations.
• Type and quality of the antenna. • Height of the antenna’s mounting location (the higher the antenna, the better the signal’s range). • Surrounding terrain (mountains and tall buildings limit the range). • Weather conditions. • Number of nearby CBs operating on the same channel. Note: Your CB radio’s transmission range is generally line-ofsight. To ensure maximum range, always keep the battery pack fully charged or use fresh batteries.
