							Troubleshooting
à Not enough range
Cause: Line of sight blocked
ÚSwitch to 5W mode 
(if available).
à Will not transmit on 5 watt range but
will transmit on the 1 watt range.
Cause: Low voltage.
ÚRecharge or replace the 
batteries.
(Use high quality alkaline 
batteries).
à Battery will not hold a charge.
Cause: Battery has developed a
memory.
ÚPeriodically, drain the NiMH 
battery before recharging.
(This can be done by 
listening to the weather 
channel until the 
battery drains).
à Strange Display
Cause: Inverted display has 
been activated.
Ú Press and hold the 
1/5Wkey

							FCC Safety Precautions
When operating your portable marine VHF radio transceiver, you should know
that the antenna radiates radio frequency energy. This radio was designed to
meet the FCCs rules and regulations for the maximum permissible exposure to
radio frequency energy. This design was tested and found to be compliant to
the strict requirements established by the FCC.
The belt clip is provided for the purpose of carrying the radio ONLY. Do not
attempt to activate the transmitter from this position unless you have installed
the proper Uniden speaker/microphone accessory.
WARNING:It is up to the user to properly operate this radio transmitter to 
insure safe operation. Please adhere to the following:
Ú Never allow children to operate the radio without adult supervision and the     
knowledge of the following safety guidelines.
Ú Hold the radio transceiver to your face, but always maintain at least a 1 inch 
separation distance between your body (including the face and eyes) and 
any surface of the radio.
Ú Never allow the antenna to touch the human body or to come within 1 inch 
when the transmitter is active.
Ú When using an external speaker or microphone, USE ONLY THE UNIDEN 
MODEL HHATL07. This accessory is designed to be used with a spacer that 
keeps the radiating parts of the portable marine VHF radio away from the 
human body at a distance where the radiated energy is below the maximum 
permissive level. Use of any other accessory for this purpose may invalidate 
your authority to operate this device!
