6.6 ENABLING S.O.S STROBE OPERATION
The S.O.S. STROBE feature utilizes the high-intensity strobe LED on the
front of the HX471S as a visual distress beacon. When enabled, the LED
blinks the internationally-recognized Morse Code “S.O.S.” message
(• • • – – – • • •) at a rate of 5 words per minute. This can be very useful in
summoning help from rescuers who may not be able to communicate with
you via radio.
1. Hold down the [MEM] key while turning the radio on to activate the emer-
gency S.O.S. Strobe. Once the radio comes on, the BUSY/TX LED will
flash the Morse Code S.O.S. message repeatedly.
2. The S.O.S. strobe function is interrupted when a signal is received or if
the squelch control is turned so audio is heard from the speaker. and
during transmission.
3. To disable the S.O.S. strobe function, turn the radio off and back on
again.
