Your Uniden PC68 Elite 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).
1
Description
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 certification, 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
certification requirements in Part 2 of the rules.
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
also decided to permit 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.
Uniden is a registered trademark of Uniden America Corporation.
Elimination of Licensing
Emergency Operation
Features, Specifications, and availability of Optional
Accessories are subject to change without notice.
All channels, except Channel 9 may be used for normal
communication. Channel 9 is reserved by the FCC for emergency
communication 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.
1. Set the switch to CH9 or turn Channel Selector knob to Channel 9.
2. Press the microphone PTT switch 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.

2. Install bracket with self-tapping screws provided.
3. Connect wiring. (See instructions for Connecting the Power Cords.)
4. Attach the microphone bracket to the side of the radio.
5. Attach radio to bracket.
MOBILE STATION ANTENNA
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, we strongly recommend 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. However, the efficiency of the short
whip antenna is less than that of a full quarter-wave
whip antenna.
MARINE INSTALLATION
Consult your dealer for information regarding marine installation. It is
important to adequately ground the system and to prevent electrolysis
between the fittings in the hull and the water.
4
Installation
Plan the location of the transceiver and
microphone bracket before beginning installation.
MOBILE STATION INSTALLATION
UC344FH 10/29/03 4:48 PM Page 4
CONNECTING THE POWER CORDS
We recommend 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.
Or, 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
5
This transceiver may be installed and used in any 12-volt DC
negative or positive ground system vehicle.
Most newer U.S. and foreign made cars, and small trucks, use a negative
ground system. Some older cars, and some new large trucks, use a positive
ground system.
With a negative ground system, the negative (-) battery terminal is usually
connected to the vehicle motor block. If you cannot determine the polarity
system of your vehicle, contact your vehicle dealer for information.
Negative Ground System
If you have a negative ground system,
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.
Positive Ground System
If you have a positive ground
system,connect the black DC power
cord from the transceiver to the negative
(-) battery terminal or other convenient
point. Then, connect the red power
cord to the vehicle chassis or the
positive (+) battery terminal.
UC344FH 10/29/03 4:48 PM Page 5
Dynamic Squelch Control automatically sets Squelch to the optimal level for
stronger signals. To scan for weaker signals, turn off Dynamic Squelch
Control and perform the following steps:
4a. Turn SQ fully clockwise so only strong
signals can get through.
4b. Turn SQ fully counter-clockwise until
you hear a hiss. Everything gets
through - noise, weak signals, and
strong signals.
4c. Turn SQ back clockwise until the hiss
stops. Only clearer signals get through.
6
To Receive
Be sure that the power source, antenna, and microphone
are properly connected before proceeding.
Set SQ only when the
radio is not receiving a
strong signal.
1. Turn unit ON by turning the
VOL clockwise. VOL Control
to a comfortable level.
2. Select CHANNEL.
3. Set switch to NB/ANL.
UC344FH 10/29/03 4:48 PM Page 6
5. Adjust RF GAIN knob (small) to
optimize reception in strong
signal areas.
7
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. Adjust MIC GAIN.
3. When the channel is clear, press the
microphone PTT switch and speak.
Function Meter
RF Meter: Measures RF Output
Power for transmitter. Press
microphone PTT switch to read
transmitting power.
S-Meter: Measures incoming signal
strength. The meter swings to indicate
signal strength. i.e. S 3, S 5, S 7 . . .
UC344FH 10/29/03 4:48 PM Page 7
To configure your CB radio to receive weather
alerts while using your CB radio:
1. Set the switch to WX.
2. Turn the Weather Channel knob to the
channel with best reception.
Left at this setting, you will hear only weather
broadcasts and Weather Alert Signals.
To use your CB radio normally while monitoring for
weather alerts, set the switch to CB.
When you hear a Weather Alert Signal, and desire to
hear weather information, return the switch to WX.
If you want to stop the weather alert signal while using your CB radio, or if
you don’t want to hear alerts, turn the Weather Channel knob to OFF.

Weather Information
Your PC68 Elite combines a CB Radio with a Weather Radio and a
Weather Alert System. The Weather Radio continually broadcasts weather
conditions. The Weather Alert System sounds a seven-second signal in the
event of severe weather.

Preventive Maintenance
Maintenance
Use only the fuse specified for your PC68 Elite.
Failure to do so may void your warranty.
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 hard ware are tight.
The PC68 Elite 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.
