3. DSC DISTRESS OPERATIONS
The audio alarm sounds while pressing the key, and the key flashes in red. The
countdown message appears on the screen while pressing the DISTRESS key
(3s → 2s → 1s → 0s).
When the countdown shows 0s, the distress alert is sent. The audio alarm sounds
for two seconds and the message "Sending DISTRESS ALERT." appears.
The DISTRESS key lights in red and only the icon for DISTRESS transmission
( ) is displayed in the tab area.
After the distress alert has been sent, the screen changes as below. Wait to re-
ceive the distress acknowledge call from a coast station. The elapsed time since
transmission is displayed. At this time, the icons for other DSC received messag-
es except the distress alert acknowledge call are not displayed. You can only con-
firm them in the log.
Note: If you do not receive the distress alert acknowledge call, the equipment au-
tomatically re-transmits the distress alert after 3 min 30 seconds to 4 min 30 sec-
onds. The equipment then awaits the distress alert acknowledge call. This is
repeated until the distress alert is acknowledged.
You can temporarily stop the countdown for next retransmission by selecting
[PAUSE] in the user options area. The [PAUSE] indication changes to [START]
and [PAUSE] is displayed instead of the countdown indication. To restart, select
[START]. The countdown restarts and the [START] indication changes to
[PAUSE].
Also, you can re-send the distress alert manually by pressing and holding the DIS-
TRESS key for four seconds.
