(Levels 00 - 15) MIC Gain: Adjusts microphone sensitivity. Delivers up to 100% modulation. With MIC Gain active, press PTT and adjust the gain levels with the Volume Control knob. (Levels 00 - 04) If Talkback is on when MIC Gain is also on, Talkback volume increases.
11. MEM/SCAN: Press to start or stop scanning modes [All Channel Scan (see page 10) and Memory Scan (see page 12)]. Press and hold to set or clear channel memory while in Memory mode. 12. 9/19/NORM: Press to switch between emergency channel 9, channel 19, and standard CB channels. 13. Frequency Display: Displays the MHz of the selected channel. Also displays menu options. 14. ANL: Turns ANL (Automatic Noise Limiter) feature on and off. ANL reduces external noise. 15.
Installation MOBILE INSTALLATION Plan the location of the transceiver and microphone bracket before beginning installation. 1. Select a location that is convenient for operating the radio but does not interfere with the driver or passenger. 2. Install bracket with self-tapping screws provided. 3. Connect power cords (see page 8). 4. Attach the microphone bracket to side of the radio. 5. Attach radio to bracket.
caution must be taken to prevent a short circuit. If in doubt, contact your vehicle dealer for information. Ground Information This transceiver may be installed and used in any 12-volt DC negative ground system vehicle. Negative Ground System With a negative ground system, the negative (-) battery terminal is usually connected to the vehicle motor block. Connect the red DC power cord from the transceiver to the positive (+) battery terminal or other convenient point.
Using Your Bearcat 880 CB MODE Be sure that the power source, antenna, and microphone are properly connected before proceeding. Basic Settings 1. 2. 3. 4. • Turn unit on. Set volume to a comfortable level. Select channel. Set noise limitations as desired (ANL/NB). Adjust Squelch. Turn SQUELCH fully clockwise so only strong signals can get through. • Turn SQUELCH fully counterclockwise until you hear a hiss.
scanning in the selected direction. • To change to Memory Channel Scan mode, press MEM/SCAN while in All Channel Scan mode (see page 12). 3. To exit All Channel Scan mode, press PTT, 9/19/NORM, WEATHER, or CB/PA. Weather Mode (WX mode) Your radio combines a CB radio with a Weather radio and a Weather Alert system. The Weather Alert system sounds a seven-second signal in the event of severe weather when you are in CB mode.
Set Weather Alert Mode Weather Alert mode only operates when you are in CB mode; it does not operate in Weather mode. In CB mode, the radio sounds an alert tone when it detects a 1050Hz tone on a weather channel. Press and hold WEATHER to turn Weather Alert on. The WEATHER LED turns on. MEMORY Mode You can select channels to store into memory and then scan only those channels. Save Channels Into Memory 1. 2. 3. 4. Tune to a channel in CB mode. Press and hold MEM/SCAN until SAVE appears (about 2 seconds).

Calibrate Standing Wave Ratio (SWR) Check and calibrate the SWR to ensure that you are using power effectively. 1. Press S/RF/CAL/SWR until CAL and a vertical status bar display on the LCD screen to indicate you are in Calibration mode. No bar graph status levels display. 2. Press and hold PTT; bar graphs status levels display the current level.
Use only the fuse specified for your Bearcat 880. Failure to do so may void your warranty. Troubleshooting In the event of system malfunction, perform the following procedures: Problem Unit does not power up No reception Poor Reception No Transmission Low Transmission Using MEM/SCAN does not access channels in memory Unit does not work as well as previously. Battery power check returned FAILLO or FAILHI. Antenna check returned FAIL. RF power diagnosis check returned FAIL.
