PLB ON UNTIL RES Q
LEAVE
G R
The system reminds you that leaving the beacon on continuously gives the
best assurance of being rescued. SAR groups need the ongoing
transmissions from the beacon to most effectively find you.
If this message is accompanied by a green LED flash, the GPS coordinates
have been sent. If accompanied by a red LED flash, the GPS coordinates
have not been sent.
NOTE: If GPS coordinates were not sent, the system will continue to attempt
to acquire the data and add it to the 406 MHz distress signal when available.
Updated GPS coordinates are sent every twenty minutes.
KEEP PLB UP RIGHT
G
The system reminds you that optimum performance of the beacon is achieved
when the antenna is pointed up and the keypad and GPS have a clear view to
the sky.
