DESCRIPTION

Your Uniden PC68LTD 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.

All channels, except Channel 9 may be used for normal communication.

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.

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

To prevent acoustic feedback, separate the microphone

from the speaker when operating the PA at high output

levels.

the receiver.

When the external speaker is plugged in, the internal

speaker is o.

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 17.4

inches (44 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 PC68LTD

TURN PC68LTD 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.

• Turn SQUELCH knob fully clockwise so only strong signals can

get through.

• Turn SQUELCH knob fully counterclockwise until you hear a

hiss. Everything gets through - noise, weak signals, and strong

signals

• Turn SQUELCH knob clockwise until the hiss stops. Only

clearer signals get through.

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

6. Press and hold PTT and check the multifunction meter. It will

show the RF output power.

7. Turn RF GAIN knob to set RF gain sensitivity. Normally, the knob is

turned clockwise to maximum.

8. Turn MIC GAIN knob to adjust microphone sensitivity for

transmission. Normally, the knob is turned clockwise to

maximum.

9. Set the brightness (BRT or DIM).

PA MODE

Using the PA mode requires an optional speaker.

1. Switch to PA.

2. Press and hold PTT to speak.

3. Release when nished.

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 nished speaking to listen for the

response.
