CAUTION
■ NEVER connect the transceiver to an AC out-
let. This may pose a re hazard or result in an
electric shock.
■ DO NOT use or place the transceiver in direct
sunlight or in areas with temperatures below
5°F (-15°C) or above 131°F (55°C).
■ KEEP the transceiver at least 1 meter away
from your vessel’s magnetic navigation

■ MAKE SURE the exible antenna and battery
cover are securely attached to the transceiver and
that antenna and battery cover are dry before
attachment. Exposing the inside of the
transceiver to water will result in serious
damage to the transceiver.
RECOMMENDATION
Clean the transceiver thoroughly with fresh
water after exposure to saltwater, and dry it
before operating. Otherwise, the transceiver’s
key, switches and controllers may become
unusable due to salt crystallization.
NOTE: DO NOT submerge the transceiver
in water if there is any reason to suspect the
waterproof protection may not be effective.
For example, in cases where the battery
cover or DC power jack rubber seal is
damaged, cracked or broken, or the
transceiver has been dropped, or when the
battery cover, antenna or DC power jack are
detached from the transceiver.
FEATURES

ment parts and/or accessories are used.

■FLOATS AND FLASHES
At the bottom of each radio is a light that blinks
while oating in the water. The LED light is
noticeable in the dark (like a ashing shing
oat) so the radio can easily be found while
in the water. The light works even when the
radio is turned OFF.

function emits a vibrating beep that helps

coming from the speaker, from the speaker
housing.
