PROFESSIONAL MOBILE CB RADIO
INTRODUCTION
Welcome to the world of Citizens Band radio communications.
Your Uniden radio is an advanced mobile transceiver designed
for use in the Citizens Band (CB) Radio Service. It will operate
on any of the 40 AM frequencies authorized by the Federal
Communications Commission (FCC). Your transceiver features
a superheterodyne circuit with Phase Locked Loop techniques to
assure precise frequency control.
SAFETY NOTICE
The antenna used for this transceiver must be properly installed
and maintained and must provide a separation distance of at least
16.92 inches (43 cm) 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 radio. 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.
CB LICENSE REQUIREMENT
U.S. users no longer need to apply for a license to use a CB
radio. However, CB radio is still considered a “license by rule”
service. This means that, while the FCC permits CB station
operation without station identification, station operators are still
required to comply with the Communications Act and with the
rules of CB Radio Service. (For more information on U.S. radio
rules, visit the FCC website at www.fcc.gov.)

EMERGENCY OPERATION
1. Press 9/19/LOCKorselectChannel9using▲and▼.
2. Press PTT on the speaker/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. 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.
INSTALLING YOUR CMX560
CONSIDERATIONS
• Try to keep the mounting location simple and practical.
When mounted, the CB should not interfere with the driver or
passengers.
• Keep the wiring pathways free from interfering with the driver
or passengers.
• Be aware of what is on the other side of the dashboard when
installing the transceiver. You do not want to drill through the
dashboard into the vehicle’s electrical system.
• Be sure that the speaker/microphone, once installed, is able to
easily stretch to the driver without interfering with the vehicle’s
controls.
• If you need to improve speaker sound, connect an external
speaker (not included) to the back of the unit (marked EXT.
SP).

CONNECT THE 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, Uniden strongly
recommends that you install only a high quality antenna.
You have just purchased a superior radio; 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.
WARNING! The antenna used for this transceiver 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 transceiver with no antenna
or with a damaged antenna cable. This can damage the
transceiver.
A short “loaded” whip antenna is easier to install on an
automobile, but its efficiency is less than that of a full quarterwave whip antenna.
Once your antenna is installed, tune it using a Standing-Wave
Ratio (SWR) meter (not included): set it to channel 20 and adjust
the antenna until the SWR is as close as 1:1 as possible.
CAUTION: Make sure the SWR is less than 2:1 before using
the transceiver. An SWR higher than 2:1 can damage the
transmitter.
Your Uniden dealer can help you select the antenna that is best
for your needs.
INSTALL TRANSCEIVER BRACKET
Place the bracket against the location you are considering. Check
the other side of the dashboard to be sure the mounting screws
