PRO 510XL Professional Mobile CB Radio
Instruction Manual
INTRODUCTION
Welcome to the world of Citizens Band radio communications. Your Uniden PRO510
radio is an advanced mobile radio 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 Radio features a
superheterodyne circuit with PHASE LOCKED LOOP techniques to assure precise
frequency control.
Safety Notice
The antenna used for this radio 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 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.
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.)

PARTS OF THE RADIO
Front
-
ANL Switch
Activates the Automatic Noise Limiter feature, which reduces background noise from the car engine and other sources. -
TX LED
Indicates when the radio is transmitting. -
S/RF (Signal/RF) Meter
Shows the strength of the received signal or the RF output. -
Channel Indicator
Displays the channel currently in use. -
Microphone Jack
Connects to the included detachable electret microphone. -
Volume Control
Powers on the radio and adjusts the volume. -
Squelch knob
Adjusts the level at which the radio squelches or suppresses weak radio signals. To filter out weaker signals and background noise, turn the knob clockwise to increase the squelch level. To decrease the squelch level so you can hear weaker radio signals, turn the knob counter-clockwise. -
Channel Selector
Selects which channel the radio will transmit or receive on.
NOTE: FCC rules reserve Channel 9 for motorist assistance and other emergency communications. Channel 9 should only be used in situations where there is immediate danger to the safety of individuals or the protection of property.
Back
-
Model number label
Shows the radio model number, FCC ID number and serial number. -
Antenna Connector
Connects to a male PL-259 external antenna cable (antenna sold separately). -
External Speaker Jack
Connects to a ⅛-inch (3.5 mm) external speaker (sold separately). -
12 Volt DC Power Cord
-
Fuse casing
Microphone -
Push-to-talk (PTT) button
Press and hold the PTT button to transmit on the selected channel. Release the button to listen for a response.
For the best sound quality, hold the microphone about 2 inches away from your mouth and speak in a normal voice.
NOTE: Make sure you have read and understood part 95 of the FCC rules and regulations before using the transmitter.
INSTALLATION
Connect the microphone
Align the microphone connector with the jack on the front of the radio. Push
the connector in firmly and secure it with the locking screw.
Connect the power
You can connect the radio to any standard 12 volt DC power source, with either
a positive or negative ground. If you don’t know whether your power supply
uses a positive or negative ground, consult the manual for your power supply
or contact the manufacturer.
WARNING! DO NOT connect this equipment to a power supply if you are not
absolutely certain of the grounding type!
-
Make sure your power supply is turned off.
-
For power supplies with a NEGATIVE ground, connect the RED lead on the radio to the power supply’s POSITIVE (+) pole, and connect the BLACK lead to the power supply’s NEGATIVE (–) pole or to a neutral ground such as the chassis.
OR
For power supplies with a POSITIVE ground, connect the BLACK lead on the radio to the power supply’s NEGATIVE (–) pole, and connect the RED lead to a neutral ground such as the chassis. -
Turn on your power supply.
-
Turn the radio’s Volume knob clockwise to power on the radio.
Installing the mounting bracket
When choosing the location for the radio’s mounting bracket, keep the
following things in mind:
► Pick a location that does not block your view, interfere with your vehicle’s
controls, or hinder your driving.
► Make sure the radio and microphone are not in front of an airbag.
► Pick a solid surface that can support the weight of the bracket and the
radio.
► Make sure there’s enough room. (You may want to put the radio in the bracket
when you’re choosing where to install the bracket.)
Once you choose the location, use the included, self-tapping screws to attach
the mounting bracket and the microphone bracket to your vehicle (you don’t
have to drill holes). Slide the radio into the bracket and use the included
knobs to hold it at the preferred angle.
Connecting an external antenna
You will need to purchase an antenna to operate the radio. However, Your
Uniden dealer can help you select the antenna that is best for your needs.
Consult the specifications in the back of this manual for detailed transmitter
and antenna information.
There are two basic types of mobile CB antennas–full-length whips and loaded
whips–with a wide variety of mounts to suit different vehicle locations.
► Choose an antenna that matches the specifications of this radio.
► Follow the manufacturer’s installation instructions carefully.
► Tune your antenna using a Standing-Wave Ratio (SWR) meter: set the radio 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 radio. An
SWR higher than 2:1 can damage the transmitter.
OPERATION AND MAINTENANCE
Basic operation
Turning the radio on| Turn the Volume knob clockwise until the display
backlight comes on.
