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.

FCC INFORMATION
WARNING!
Read this information before using
the radio. In August 1996 the Federal
Communications Commission (FCC) of the United
States with its action in Report and Order FCC
96-326 adopted an updated safety standard for
human exposure to radio frequency
electromagnetic energy emitted by FCC regulated
transmitters.
Those guidelines are consistent with the safety
standard previously set by both U.S. and
international standards bodies. The design of the
radio complies with the FCC guidelines and these
international standards.
Never allow children to operate the radio without
adult supervision and the knowledge of the
following guidelines.
WARNING!
It is up to the user to properly operate
this radio transmitter to insure safe operation.
Please adhere to the following:
Use only the supplied or an approved antenna.
Unauthorized antennas, modifications, or
attachments could impair call quality, damage the
radio, or result in violation of FCC regulations.
Do not use the radio with a damaged antenna.
If a damaged antenna comes into contact with the
skin, a minor burn may result. Please contact your
local dealer for a replacement antenna.
Body-worn Operation
This device was tested for typical body-worn
operations using the supplied belt-clip.
To maintain compliance with FCC RF exposure
requirements, Body-worn operations are restricted
to the supplied belt-clip.
For hand-held operation, the radio should be held
1 inch from the user's face. The use of accessories
that do not satisfy these requirements may not
comply with FCC RF exposure requirements and
should be avoided.
For more information about RF exposure, please
visit the FCC web site at www.fcc.gov.
