DESCRIPTION

Your Uniden PC68LTX 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 OPERATIONS

1. set the switch to CH9 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.
4. All channels, except Channel 9 may be used for normal communication.
5. Channel 9 is reserved by the FCC for emergency communications involving the immediate safety of individuals or protection of property. Channel 9 may also be used to render assistance to a motorist.
6. This is an FCC rule and applies to all operators of CB radios.

When the external speaker is plugged in, the internal speaker is off.

19| POWER : Connects DC power to transceiver.

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.

Mobile Antenna
WARNING! The antenna used for this radio must be installed at least 16.92 inches (43 cm) away from all persons. The antenna must not be collocated or used with any other antenna or transmitter.

CAUTION
Never operate your radio with no antenna or with a damaged antenna cable. This can damage the radio. You must purchase an antenna to operate this radio. 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
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.

USING YOUR PC68LTX TURN PC68LTX ON/OFF
Turn the VOLUME knob clockwise until the unit turns on and the display backlight turns on. Turn the VOLUME knob counter-clockwise to turn the unit off.

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

1. Turn unit on. Set volume to a comfortable level.
2. Set switch to CB.
3. Turn the CH knob to select a CB channel.
4. Set noise limitations switch to NB/ANL.
5. Adjust squelch.
6. Turn SQUELCH knob fully clockwise so only strong signals can get through.
7. urn SQUELCH knob fully counterclockwise until you hear a hiss. Everything gets through – noise, weak signals, and strong signals •
8. Turn SQUELCH knob clockwise until the hiss stops. Only clearer signals get through.
9. Set SQUELCH only when the radio is not receiving a strong signal.
10. Press and hold PTT and check the multifunction meter. It will show the RF output power.
11. Turn RF GAIN knob to set RF gain sensitivity. Normally, the knob is turned clockwise to maximum.
12. Turn MIC GAIN knob to adjust microphone sensitivity for transmission. Normally, the knob is turned clockwise to maximum.
13. Set the brightness (BRT or DIM).

PA MODE

1. Using the PA mode requires an optional speaker.
2. Switch to PA.
3. Press and hold PTT to speak.
4. Release when finished.

To prevent acoustic feedback, separate the microphone from the speaker when operating the PA at high output levels. If you are in PA mode but not pressing PTT, the radio receives CB transmissions and transmits them through the PA speaker. You cannot respond to the transmission.

HI CUT/OFF
The Hi Cut function reduces high frequencies. Switch to HI CUT to turn off higher frequencies.

TO TRANSMIT/RECEIVE
Perform a voltage Standing Wave Ratio (SWR) measurement prior to using the transmitter. An 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. Adjust MIC GAIN.
3. When the channel is clear, press the microphone PTT and speak.
4. Release PTT when you are finished speaking to listen for the response.

PREVENTIVE MAINTENANCE
Every six months:

• Check the Standing Wave Ratio (SWR).
• Be sure all electrical connections are tight.
• Inspect antenna coaxial cable for wear or breaks in shielding.
• Be sure all screws and mounting hardware are tight.

The PC68LTX 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.
3. Use only the fuse specified for your PC68LTX. Failure to do so may void your warranty.
