Uniden 550W Two-Way Radio User Manual

Important: Changes or modifications to this unit not expressly approved by Uniden could void your
authority to operate this unit. Do not open your radio to make any internal adjustments. 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 using the proper test equipment. 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.
Audio Accessories
: Do not operate the radio with audio accessories at high volume levels. Hearing
experts advise against continuous high volume operation. If you experience a ringing in your ears,
reduce the volume level or discontinue use. Always make sure the radio is turned off before plugging
audio accessories into the accessory jack.
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.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including interference that
may cause undesired operation of the device.
