DesCription  
Your Uniden Bearcat 880 represents the highest quality communications  
device designed for use in the Citizens Band Radio Service. It will  
operate on any of the 40 AM frequencies authorized by the Federal  
Communications Commission (FCC).  
The Citizens Band Radio Service is under the jurisdiction of the Federal  
Communications Commission (FCC). Any adjustments or alterations which would  
alter the performance of the transceiver's original FCC type acceptance, or which  
would change the frequency determining method, are strictly prohibited.  
Replacement or substitution of crystal, transistors, ICs, regulator diodes, or any  
other part of a unique nature, with parts other than those recommend by Uniden,  
may cause violations of the technical regulations in Part 95 of the FCC Rules or in  
violation of type acceptance requirements in Part 2 of the rules.  
emergenCy operation  
1. Press 9/19/NORM or turn Channel Selector knob to Channel 9.  
2. Press PTT and speak clearly.  
3. If there is no response, select an active channel and ask that party  
to relay your emergency broadcast on Channel 9.  
All channels except Channel 9 may be used for normal communication. The FCC  
reserves Channel 9 for emergencies involving the immediate safety of individuals  
or protection of property. Use Channel 9 to render assistance to a motorist.  
This is an FCC rule and applies to all CB radio operators.

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.

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 ‘loadedwhip 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  
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  
8
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, noise-  
cancelling 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  
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.  
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 (see page 12).  
8. Set LCD Contrast (see page 13).  
9. Set Brightness (see page 13).  
all Channel sCan  
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).  
SCAN 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 counter-  
clockwise 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 (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. 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.  
You cannot change ANL or NB settings while in WX mode. The radio will sound an  
alert tone.  
10  
Set Weather Scan Mode  
Weather Scan mode allows the radio to move to the next weather  
channel if no signal is detected after 3 seconds. Set Weather Scan mode  
to ON or OFF through the menus.  
1. Press MENU/OK to activate the menus. COLOR displays.  
2. Turn the Channel Selector knob to cycle through the menu op-  
tions until WXSCAN displays.

Left at these setting (WX mode, WX Scan), you will hear only weather  
broadcasts and Weather Alert signals. To use your CB radio normally  
while monitoring weather alerts, press WEATHER again.  
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.

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.  
15  
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.
