FEATURES
☞ Floats on water
The transceiver floats in fresh or salt
water even when the supplied acces-
sories are attached.
• When a third-party battery pack, strap, an-
tenna, etc. is used, it may sink.
☞ Floats and fl ashes
An LED sends out intermittent light from
a transparent section on the bottom of
the radio, while floating in the water.
As the LED light stands out in the dark
(like a flashing fishing float), the radio
can be easily retrieved from the water.
This function works even when the
radio is turned OFF.
