DESCRIPTION

Your Uniden CMX760 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 CMX760 is designed to provide years of trouble-free service. Its slim profile can fit easily under the seat to free up space in the vehicle’s cabin. Its rugged components and materials are capable of withstanding harsh environments. Please read this Owner’s Manual carefully to ensure you gain the optimum performance of the unit.

• The Citizens Band Radio Service is under the jurisdiction of the Federal Communications Commission (FCC). Any adjustments or alterations that would alter the performance of the radio’s original FCC-type acceptance, or that 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 recommended by Uniden, may cause violations of the technical regulations in Part 95 of the FCC Rules or violation of type acceptance requirements in Part 2 of the rules.

This is an FCC rule and applies to all CB radio operators.

INSTALLATION

You can install the CMX760 either on top/ underneath a flat surface like a dashboard or under the driver’s seat in a vehicle. Select a location that is convenient for operating the radio but does not interfere with the driver or passenger. Plan the location of the radio and microphone brackets before beginning installation.

The basic steps to install this unit are:

• Connect Power
• Connect Antenna
• Install Microphone Hanger/Connect Microphone
• Install Radio Bracket/Install Radio

CONNECT POWER

• Uniden recommends connecting the power lead to the Ignition Switch Accessory Terminal. This way, the radio 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.
• The CMX760 can operate on a 12VDC power supply.

Ground Information
This radio may be installed and used in any 12-volt DC negative ground system vehicle.

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 radio to the positive (+) battery terminal or other convenient point.  Then connect the black power cord to the vehicle chassis or negative (-) battery terminal.

Connect Power

1. Connect the power cord to the power connector from the radio.
2. Connect the red DC power cord to the Ignition Switch Accessory Terminal or the positive (+) battery terminal.
3. Next, connect the black power cord to the Ignition Switch Accessory Terminal, the vehicle chassis, or the negative (-) battery terminal.
4. Start the vehicle. The unit should turn on. Turn the vehicle off. The unit should turn off.

MARINE INSTALLATION

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

CONNECT ANTENNA

Because the FCC limits the maximum power output of the transmitter, the quality of your antenna is essential. To achieve the maximum transmission distance, Uniden strongly recommends that you install only a high-quality antenna. You have just purchased a superior radio; 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.

CAUTION: Never operate your radio with no antenna or with a damaged antenna cable. This can damage the radio.

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. Once your antenna is installed, tune it using a Standing-Wave Ratio (SWR) meter (not included): set it to channel 20 and adjust the antenna until the SWR is as close as 1:1 as possible.

CAUTION: Make sure the SWR is less than 2:1 before using the radio. An SWR higher than 2:1 can damage the radio.

Safety Notice
The antenna used for this radio must be properly installed and maintained must provide a separation distance of at least 16.9 inches (43 cm) 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 radio. 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.

INSTALL MICROPHONE HANGER/CONNECT MICROPHONE

Install Microphone Hanger

1. Find a location to install the microphone hanger. Install it, using the same precautions as installing the radio. Adjust wiring if necessary.
2. Hang the speaker/microphone onto the hanger.

Connect Microphone

1. Pull back the MIC jack rubber cover and slide it back along the cord.
2. Insert the MIC jack into the radio’s MIC socket until it clicks into place.
3. Gently tug on the cable to be sure the connection is locked.
4. Slide the rubber cover down the cable and cover the MIC jack to seal it from dust.

If you want to use the extension cable, connect the cable to the radio and the MIC to the other end of the extension cable.

Disconnect the Microphone

1. Pull back the MIC jack rubber cover and slide it back along the cord.
2. Push down the MIC jack’s lock tab; tug gently on the MIC cord until it disconnects.

If you are using the extension cable, disconnect the cable from the radio and the MIC from the other end of the extension cable.

INSTALL RADIO BRACKET/INSTALL RADIO

The CMX760 uses a slide mount assembly to mount the unit onto a surface. It can be mounted either below or on top of a surface.

Attach Side Rails

1. Align the guide rails along the sides of the radio and insert L-tabs into the L-tab slots. Be sure the slide mount latches face outward.
2. Use the screws provided to fasten the guide rails into position on the radio.

Attach Bracket/Install Radio

1. Using the screws provided, screw the bracket into a stable, level surface. If mounting the radio in a vehicle, for example, screw the bracket onto the top of the dashboard or underneath the dashboard. Be sure the words “FRONT-SLIDE IN” are visible from the front of the bracket.

Be sure you do not mount the bracket where the screws can damage any wiring or hardware. Move the wiring/hardware out of the way or relocate the radio bracket.

2. Slide the back of the radio into the bracket until the slide mounts latch and click into place.

EMERGENCY OPERATION

1. Press CH9/19 or use ▲ or ▼to select 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 the protection of property. Use Channel 9 to help a motorist. This is an FCC rule and applies to all CB radio operators.

SPEAKER/MICROPHONE LCD DISPLAY

This LCD layout is for reference only. Different icons are displayed depending on the scanner status. Dimensions and layout may vary slightly.

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 CMX760 is designed to give you years of trouble-free service. There are no user-friendly parts inside. Except for the fuse in the DC power cord, no maintenance is required.

To replace a blown fuse:

1. Press the 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 of fuse.

Use only the fuse specified for your CMX760.  Failure to do so may void your warranty.
