SAFETY NOTICE
The antenna used for this radio must be properly installed and
maintained and must provide a separation distance of at least 34 cm
(13.4 Inches) 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
transceiver. 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.
L’appareil est conforme aux normes d’Industrie Canada. Son
fonctionnement est soumis aux deux conditions suivantes : (1) Ce
dispositif ne doit pas causer d’interférences et (2), il doit pouvoir accepter
les interférences, incluant celles pouvant nuire à son fonctionnement
normal.
Changes or modifications to this product or use of accessories not

DESCRIPTION
Your PC687 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 OPERATION
1. Move the CH9/OFF switch to CH9; the radio automatically tunes
to Channel 9 and disables the channel selector.
2. Press and hold PTT and speak clearly. Release PTT after speaking.
3. If there is no response, move the CH9/OFF switch to OFF, go to
CB mode, and select Channel 19.
4. Press and hold PTT and speak clearly. Release PTT after speaking.
5. If there is still no response, nd a party on another 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 protection of property. Use Channel 9 to render
assistance to a motorist.
This is an FCC rule and applies to all CB radio operators.

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 9).
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 13.4
inches (34 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
9
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.
Wireless CB Microphone Installation (Optional)
Your PC687 is compatible with Uniden’s BC906W Wireless CB
Microphone. With a range up to 300 feet, the BC906W allows you to use
your CB to communicate even when you need to get out of your vehicle.
Follow the instructions provided in the BC906W kit to install the wireless
microphone.
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.
10
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 PC687
TURN PC687 ON/OFF
Turn the VOL knob clockwise until the unit turns on and the display
backlight turns on.
Turn the VOL knob counter-clockwise to turn the unit off.
CB MODE
Be sure that the power source, antenna, and microphone are properly
connected before proceeding.
Basic Settings
1. Turn unit on. Set volume to a comfortable level.
2. Set switch to CB.
3. Select a CB channel (CH knob).
4. Set noise limitations as desired (NB/ANL/OFF switch).
5. Adjust squelch.
• Turn SQ knob fully clockwise so only strong signals can get
through.
• Turn SQ knob fully counterclockwise until you hear a hiss.
Everything gets through - noise, weak signals, and strong
signals
• Turn SQ 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
