WATERPROOF SPECIFICATIONS
The Atlantis 275 is a submersible radio, complying with
floating IPX8 water-resistant standards. The radio can be
submerged in 1.5 meter of water for 30 minutes without
damage.
CAUTION! The radio will only meet this rating if fully
assembled and all rubber seals are well maintained and
correctly fitted. This means that the speaker mic cover must be
securely fastened.
After your radio is submerged in water, you might notice that
the sound is distorted. This is because there is still water
remaining in and around the speaker and microphone. Just
shake the radio to clear excess water, and the sound should
return to normal.
If your radio is exposured to salt water, clean it thoroughly
with fresh water and dry it before turning it on. The Atlantis
275 has a special tone that will vibrate the speaker to
remove water inside the casing (see page E-18).
The charger is not waterproof.

WEATHER MODE
The NOAA weather channels cooperate with the FCC to alert
you of other hazards besides weather (child abduction alerts,
nuclear, biological, etc.). In weather mode, the radio monitors
one of the ten NOAA weather channels. If any type of alert
is received, the radio sounds an alert tone and the display
blinks.

Weather mode with Weather Alert Watch
Because weather mode already monitors the weather
channels, you don’t need Weather Alert Watch to check
the weather channel every seven seconds. If you activate
Weather Alert Watch while operating in weather mode,

is detected, the radio sounds an alert tone and turns the
speaker back on. This mode is very useful when you are
anchoring for the night but want to keep informed of hazards.

Due to its rugged design, your radio requires very little
maintenance. However, it is a precision electronic instrument,
so you should follow a few precautions:
xx If the antenna has been damaged, do not transmit except
in an emergency situation. Transmitting with a defective
antenna may cause further radio damage.
xx You are responsible for continued FCC technical
compliance of your radio.
xx You should arrange for periodic performance checks with
your Uniden dealer.

REGULATIONS AND SAFETY WARNINGS
WARNING! Read this information before using the radio.
MARITIME RADIO SERVICES OPERATION
Warning! This transmitter will operate on channels/
frequencies that have restricted use in the United States.
The channel assignments include frequencies assigned for
exclusive use of the U.S. Coast Guard, use in Canada, and
use in international waters. Operation on these frequencies
without proper authorization is strictly forbidden. See pages
E-21 through E-26 for tables of the available channels and
their uses. If you are still not certain which channels to use,
see the FCC maritime radio page at the FCC website
(http://wireless.fcc.gov/marine/) or contact the FCC Call
Center at 1-888-CALL-FCC. For individuals requiring a
license, such as commercial users, you should obtain a
license application from your nearest FCC field office (for US
users) or Industry Canada (for Canadian users).
BASIC RADIO GUIDELINES
You should familiarize yourself with the rules on marine
radios and be aware of which rules apply to your boat.
Complete guidelines for all ship and marine radio types can
be found at the US Coast Guard website under the topic
Radio Info for Boaters (the direct link is
http://www.navcen.uscg.gov/marcomms/boater.htm).
Here are a few guidelines that affect nearly all boaters.
xx If you have a VHF radio on your boat, you must maintain
a watch on channel 16 (156.800 MHz) whenever the
radio is not being used to communicate. Starting in 2004,
if a radio is carried, it must be on and set to channel 16
whenever your boat is underway.
xx If you hear a distress call, wait a few minutes to let a
shore station or Coast Guard vessel respond. If no other
E-28
Uniden Atlantis 275 Radio Owner’s Manual
station has responded after 5 minutes, you must respond
to the distress call.
xx Do not make false mayday or distress calls as a prank or
to test your radio. (This is essentially like making a false
9-1-1 call; you may be subject to fines.)
FCC/Industry Canada Information
xx Certification: FCC Part 80 or RSS-182
xx Output Power: 6W
xx Emission: 16K0F3E
xx Transmitter Frequency Range: 156.025-157.425 MHz
This device complies with Part 15 of the FCC Rules.
Operation is subject to the condition that this device does not
cause harmful interference.
Unauthorized changes or modifications to this equipment
may void compliance with the FCC Rules. Any change
or modification must be approved in writing by Uniden.
Changes or modifications not approved by Uniden could void
the user’s authority to operate the equipment.
FCC RF Exposure Information
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
Do not use the radio with a damaged antenna. If a damaged
antenna comes into contact with the skin, a minor burn may
result.
Uniden Atlantis 275 Radio Owner’s Manual
E-29
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 website at www.fcc.gov.
Lithium Ion Battery Warning
This equipment contains an internal rechargeable Lithium Ion
battery. The rechargeable Lithium Ion battery contained in
this equipment may explode if disposed of in a fire.
Do not short-circuit the battery.
Do not use any charger other than the one specified in the
owner’s manual to charge the rechargeable battery used in
this equipment. Using a different charger may damage the
battery or cause the battery to explode.
Avoid exposing the battery to direct sunlight, heated cars, or
temperatures below -4°F (-20°C) or above +140°F (+60°C).
Exposing the chemical contained within the battery to
temperatures above +140°F (+60°C) may cause the battery
to rupture, fail, or reduce performance.
In case of exposure to the cell contents, wash the affected
area thoroughly and seek medical attention.
