Choosing a Channel
Your radio has 22 channels and 38 CTCSS codes
you can use to talk to others. In order to speak to
someone, each of you must be set to the same
channel and CTCSS code.
To choose a channel:

ch and press the vol ▲or ▼key to increase or
decrease the channel number displayed.
Choosing a CTCSS Code
Each of the channels 1-22 may have any one of
the codes, OFF or 1-38 selected. Code "OFF"
indicates no CTCSS code selected and your radio
can receive a signal regardless of the code settings
of the transmitting radio.
1) Enter the Menu. The CTCSS code on the LCD
display will flash.
2) Press the vol ▲or ▼key to increase or
decrease the code number displayed. You can

This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference
received, including interference that may cause
undesired operation.
Important: Changes or modifications to this unit
not expressly approved by Uniden could void your
authority to operate this unit. Your radio is set up
to transmit a regulated signal on an assigned
frequency. It is against the law to alter or adjust the
settings inside the radio to exceed those limitations.
Any adjustments to your radio must be made by
qualified technicians.
To be safe and sure:
• Never open your radio’s case.
• Never change or replace anything in your radio
except the batteries.
Your radio might cause TV or radio interference
even when it is operating properly. To determine
whether your radio is causing the interference, turn
it off. If the interference goes away, your radio is
causing it. Try to eliminate the interference by
moving your radio away from the receiver. If you
cannot eliminate the interference, the FCC requires
that you stop using the radio.
Hazardous Environments: Do not operate the
radio in hazardous environments. Explosion or fire
may result. Do not operate the radio near
unshielded electrical blasting caps.
Under certain conditions, radios can interfere with
blasting operations and may cause an explosion.
Turn your radio OFF to prevent accidental
transmission when in a blasting area or in areas
posted: "Turn off two-way radio." Construction
crews often use remote control RF devices to set
off explosives.
Care and Safety: To clean the radio, use a soft
cloth dampened with water. Do not use cleaners or
solvents because they can harm the body of the
unit and leak inside, causing permanent damage.
Use a dry, lint-free cloth to clean the battery
contacts. Do not submerge the unit in water. If the
unit gets wet, turn it off and remove the batteries
immediately.
Dry the battery compartment with a soft cloth to
minimize potential water damage. Leave the battery
compartment cover off overnight to ensure
complete drying. Do not use the radio until the unit
is completely dry.
Important: Evidence of original purchase is
required for warranty service.
