3UNPACKINGCarefully unpack your Bearcat 880 and check the contents against this list: Bearcat 880 CB 2-way mobile radio Microphone Mounting Bracket Kit DC Power Cord Reference Guide Part 95 Subpart D (FCC Rules) If any items are missing or damaged, contact your place of purchase immediately. 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. ELIMINATION OF LICENSING The FCC has ruled that CB Radio Service operators are no longer required to obtain an FCC License to operate their CB equipment. In doing so, the FCC now also permits CB station operation without station identification. Elimination of individual station licenses does not reduce the operating privileges or responsibilities of CB users. An operator of a CB radio station is still required to comply with the Communications Act and with the rules of Citizens Band Radio Service.
4EMERGENCY OPERATION 1. Press 9/19/NORM or turn Channel Selector knob to Channel 9. 2. Press PTT switch on microphone 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 emergency communications 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. CONTROLS AND FUNCTIONS1 42 5 67151413111098 123161. Volume Control knob with Power On/OFF2.

617. Antenna socket: Connects antenna to the unit.18. PA SP: Connects optional external 8-ohm, 4-watt speaker for use as a public address system. To prevent acoustic feedback, separate the microphone from the speaker when operating the PA at high output levels. 19. EXT. SP: Connects an 8-ohm 4-watt speaker to remotely monitor the receiver. When the external speaker is plugged in, the internal speaker is o. 20. POWER: Connects DC power to transceiver. 21. Fuse INSTALLATION MOBILE STATION 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 wiring (see page 7). 4. Attach the microphone bracket to side of the radio. 5. Attach radio to bracket. Mobile Station AntennaBecause 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
7for 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 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. MARINE INSTALLATION Consult your dealer for information regarding marine istallation. It is important to adequately ground the system and to prevent electrolysis between the fittings in the hull and the water.
8USING YOUR BEARCAT 880S/RF/SWR METER You can check your incoming and outgoing signal strength and wattage as you use your Bearcat 880. The 12-column LCD display (refer to item number 3 on page 4) displays this data. Press and hold the PTT button on the microphone to see the RF output power levels. Release the PTT button to see incoming signal strengh. Press and release S/RF/SWR to cycle through these measurements as well.TO RECEIVE SIGNALSBe sure that the power source, antenna, and microphone are properly connected before proceeding. 1. Turn unit ON. Set VOLUME to a comfortable level. 2. Select CHANNEL. 3. Set noise limitations as desired (ANL/NB).Dynamic Squelch Control automatically sets Squelch to the optimal level for stronger transmission and signal clarity. To scan for weaker signals, turn off Dynamic Squelch Control and perform the following steps: 4. Turn SQUELCH fully clockwiseso only strong signals can get through. 4b. Turn SQUELCH fullycounterclockwise until you hear a hiss. Everything gets through - noise, weak signals, and strong signals.
94c. Turn SQUELCH backclockwise until the hiss stops. Only clearer signals get through. Set SQUELCH only when the radio is not receiving a strong signal. 5. Turn the RF Gain knob to set the RF gain sensitivity to Local or Distance. 6. Press MIC Gain to adjust the microphone sensitivity.TO TRANSMIT Perform a voltage Standing Wave Ratio (SWR) measurement prior to using the transmitter. A SWR ratio in excess of 2:1 may damage the transmitter. Be sure to read and understand Part 95, FCC Rules and Regulations before operating your transmitter. 1. Select a channel. 2. Press MIC Gain to adjust the microphone sensitivity. 3. When the channel is clear, press the PTT button and speak. Release the button when you have nished speaking.You can also transmit while you are on emergency channels 9 or19. Press the PTT button to transmit emergency information.PREVENTIVE MAINTENANCE Every six months: 1. Check the Standing Wave Ratio (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. PTT
10MAINTENANCE 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 specied for your Bearcat 880. Failure to do so may void your warranty.
