• Turn off your radio when on board an aircraft. Any use of
a radio must be in accordance with applicable regulations
per airline crew instructions.
Avoid Burns
Antennas
• Do not use any portable radio that has a damaged
antenna. If a damaged antenna comes into contact with
the skin when the radio is in use, a minor burn can result.
Batteries (If appropriate)
• When the conductive material such as jewelry, keys or
chains touch exposed terminals of the batteries, may
complete an electrical circuit (short circuit the battery)
and become hot to cause bodily injury such as burns.
Exercise care in handling any battery, particularly when
placing it inside a pocket, purse or other container with
metal objects.
Long transmission (If appropriate)
• When the transceiver is used for long transmissions, the
radiator and chassis will become hot.
Safety Operation

use only in dry locations/conditions.
• Do not disassemble the charger, that may result in risk of
electrical shock or fire.
• Do not operate the charger if it has been broken or
damaged in any way.
• Do not place a portable radio in the area over an air bag
or in the air bag deployment area. The radio may be
propelled with great force and cause serious injury to
occupants of the vehicle when the air bag inflates.
To reduce risk
• Pull by the plug rather than the cord when disconnecting
the charger.
• Unplug the charger from the AC outlet before attempting
any maintenance or cleaning.
