INSTALLATION

MOBILE INSTALLATION

NOTE
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.
4. Attach the microphone bracket to side of the radio.
5. Attach radio to bracket.

Mobile Antenna

Because the maximum power output of the transmitter is limited by the FCC, the quality of your antenna is very important. To achieve the maximum transmission distance, Uniden strongly recommends that you install only a high quality antenna. You have just purchased a superior transceiver - don't diminish its performance by installing an inferior antenna.
Only a properly matched antenna system will allow maximum power transfer from the 50 ohm transmission line to the radiating element. Your Uniden dealer is qualified to help you select the proper antenna for your requirements. A whip style antenna may be used for automobile installation.
A short 'loaded' whip antenna is easier to install on an automobile, but its efficiency is less than that of a full quarter-wave whip antenna.

Connecting the Power Cords

Uniden recommends connecting the power lead to the Ignition Switch Accessory Terminal. This way, the transceiver is automatically turned off when the ignition switch is turned off.
As an alternative, the power cord may be connected to an available terminal on the fuse block or to a point in the wiring harness. However, caution must be taken to prevent a short circuit. If in doubt, contact your vehicle dealer for information.

Ground Information

NOTE
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. Then connect the black power cord to the vehicle chassis or negative (-) battery terminal.

INSTALL 6-PIN TO 4-PIN ADAPTER

The Bearcat 880 is pre-configured for Uniden's new 6-pin wireless, noisecancelling technology, available in 2012. Your Bearcat 880 comes with an adapter to connect the radio's 6-pin microphone to a current standard 4-pin microphone.

1. Insert the 6-pin side of the adapter into the Bearcat 880 6-pin microphone connection.
2. Plug a standard 4-pin microphone connector into the 4-pin side of the adapter.

MARINE INSTALLATION

Consult your dealer for information regarding marine installation. It is important to adequately ground the system and to prevent electrolysis between the fittings in the hull and the water.

USING YOUR BEARCAT 880

CB MODE

NOTE
Be sure that the power source, antenna, and microphone are properly connected before proceeding.

BASIC SETTINGS

1. Turn unit on. Set volume to a comfortable level.
2. Select channel.
3. Set noise limitations as desired (ANL/NB).
4. Adjust Squelch.
   • Turn SQUELCH fully clockwise so only strong signals can get through.
   • Turn SQUELCH fully counterclockwise until you hear a hiss. Everything gets through - noise, weak signals, and strong signals
   • Turn SQUELCH back clockwise until the hiss stops. Only clearer signals get through.

   NOTE
   Set SQUELCH only when the radio is not receiving a strong signal.

5. Turn RF Gain to set RF gain sensitivity.
6. Press MIC Gain to toggle microphone sensitivity between High and Low. (LED on = High; LED off = Low)
7. Set Backlight color.
8. Set LCD Contrast.
9. Set Brightness.

When All Channel Scan is on, the radio scans channels until it receives a signal. It will move to the next channel if no signal is received after 3 seconds.

1. Press MEM/SCAN once if in CB mode (twice if in MEM mode). displays.
2. The radio begins scanning upward through the channels.
   • To skip the channel the radio has stopped on, turn Channel Selector clockwise to move to the next channel or counterclockwise to move to the previous channel. The radio continues scanning in the selected direction.
   • To change to Memory Channel Scan mode, press MEM/SCAN while in All Channel Scan mode.
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. The Weather radio continually broadcasts weather conditions when you are in Weather mode.

1. Press WEATHER. Your radio is now in Weather radio mode.
2. Select 1 of 7 weather channels using Channel Selector.

NOTE
You cannot change ANL or NB settings while in WX mode. The radio will sound an alert tone.

PREVENTIVE MAINTENANCE

Every six months:

1. Check the SWR.
2. Be sure all electrical connections are tight.
3. Inspect antenna coaxial cable for wear or breaks in shielding.
4. Be sure all screws and mounting hardware are tight.

MAINTENANCE

The Bearcat 880 is designed to give you years of trouble-free service. There are no user-serviceable parts inside. Except for the fuse in the DC power cord, no maintenance is required.
To replace a blown fuse:

1. Press ends of the fuse holder together. Twist to open. Carefully separate the two pieces.
2. Remove the fuse and inspect. If blown, replace with the same type fuse.

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	Suggestion
Unit does not power up	Check power cord connections. Check fuse. Check vehicle electrical system.
No reception	Check microphone connection. Set CB/PA to CB. Check VOLUME and SQUELCH. Check antenna. Check antenna connection. Adjust RF Gain.
Poor Reception	Check VOLUME and SQUELCH. Be sure antenna SWR is normal. Adjust RF Gain.
No Transmission	Set CB/PA switch to CB. Check microphone connection. Adjust MIC Gain.
Low Transmission	Adjust MIC Gain.
Using MEM/SCAN does not access channels in memory	Verify that there are channels saved into memory.
Unit does not work as well as previously.	Turn the power off then back on. The channels will reset.
Battery power check returned or .	Make sure your power wires have a good connection. Check your battery charge; it needs to be fully charged. Lower voltage will cause a failure. Check your alternator.
Antenna check returned .	Make sure your antenna ground is good. Check for damage to the antenna. Check the SWRs at a CB shop. High SWRs will damage the radio.
RF power diagnosis check returned .	Make sure your antenna ground is good. Check for damage to your antenna. Check the antenna connection on the back of the radio. Be sure it is tight.

If you do not get satisfactory results after performing these checks, call the Uniden Customer Service Centerat 1-800-297-1023, 8:00 a.m. to 5:00 p.m. CST, Monday through Friday.

RADIO CODE DEFINITIONS

The following list contains common "10-Codes" used by CB radio operators for faster communication and better understanding.

SAFETY NOTICE

The antenna used for this radio must be properly installed and maintained and must provide a separation distance of at least 34 cm (13.4 Inches) from all persons and must not be collocated or operated in conjunction with any other antenna or transmitter. Never transmit if any person is closer than the specified distance to the antenna.
Note that Uniden does not specify or supply any antenna with this transceiver. While a 0 dBi gain antenna is normal for a typical installation, the above limit applies to any antenna with up to 3 dBi gain.
Changes or modifications to this product or use of accessories not expressly approved by Uniden, or operation of this product in any way other than as provided in the Uniden Owner's Manual could void your authority to operate this product.
