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.

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.

Page 8
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.
8
Page 9
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
9
Page 10
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.
10
Page 11
MULTI-FUNCTION METER
RF Meter: Measures RF Output Power for transmitter. To use,
set the
meter switch at S/RF. Press microphone PTT switch to read transmitting
power.
S-Meter: Measures incoming signal strength. To use,
set the
meter switch
at S/RF. The meter swings to indicate signal strength.
i.e. S 3, S 5, S 7 . . .
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 PC68LTD 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 specied for your PC68LTD. Failure to do so may void
your warranty.
TROUBLESHOOTING
In the event of system malfunction, perform the following procedures:
Problem Suggestion
Unit does not power up Check ignition key position.
Check power cord connections.
Check fuse.
Check vehicle electrical system.
11
