will count down (3-2-1) and then transmit the Dis-
tress Alert. The backlight of the display and keypad

tress call is repeated in 4 minute intervals until an
acknowledgment is received.

ceived, a distress alarm sounds and channel 16

RECEIVED ACK: acknowledgment signal is re-
ceived.

other vessel or coast station.
