8.7. DSC DISTRESS call

8.7.a Sending a DISTRESS call
IMPORTANT! You can only send a DSC call if you have been assigned an individual MMSI code
and this code has been programmed into the transceiver (otherwise the following commands
will be deactivated). For this operation, see par. 10.10.
Sending a distress call without founded reason is a criminal offence. Never use this fun-
ction unless you find yourself in a situation that merits asking for help.
You can carry out the distress call through the following procedure:
1. Open the DISTRESS cover by pushing it to the right and hold it open.
2. Press momentarily the DISTRESS-button below. The display shows: (S)
3. Press the function key corresponding to "Undefined" in order to se-
lect the nature of the call (the pre-selection is UNDEFINED):
A. UNDEFINED
B. ABANDONING
C. PIRACY
D. M.O.B. (man over board)
E. FIRE
F. FLOODING
G. COLLISION
H. GROUNDING
I. LISTING
L. SINKING
M. ADRIFT
4. To send out the distress call hold down the DISTRESS-button for 5
seconds. An acoustic alert will emit and the distress call will be carried
out on channel 70 even when the channel is in use.
5. After the distress call, the transceiver will simultaneously check chan-
nel 70 and channel 16 on a receipt of DSC confirmation and meanwhile
appears following: (T)
6. At this point:
- If the distress call is received and confirmed by another DSC radio station, the acoustic
alarm will stop sounding and the display will return to normal use in VHF mode on channel
16, sending on high transmission power.
- If no confirmation is received, the device will re-send the distress call at intermissions of 3.5
– 4.5 minutes (even with channel 70 in use), until a confirmation is received or until the user
manually cancels the call through the C-button.
Pressing button 16, the transceiver will return to normal VHF operation, but the call will
not be cancelled and the person who responded to the call may not have called off rescue
operations.
If, at step 4, the user stops pressing the DISTRESS button before 5 seconds have elapsed, the
distress call will not be sent. To exit and return to VHF mode, press button 16.
The acoustic alarm will only stop definitively once the transceiver has received confirmation
from the receiver of the call.
It is possible to arrest the acoustic alarm by pressing the button C or 16.
