Cancelling a distress alert
If a DSC distress alert is sent accidentally, cancel it immediately
on the RD68 by pressing the C button to prevent repeats, then
make the following announcement on channel 16 -
“This is (name of vessel, callsign, MMSI)”
“Cancel DSC Alert sent (date & time UTC)”
Do not simply cancel the DSC alert without verbally cancelling
it as well, otherwise the rescue authorities will not be aware
that this is a false alarm.
Alerting all vessels within range
If the vessel is outside of coast radio range and needs to issue a
safety warning to all vessels within radio range, transmit an All
Ships Safety call by DSC. After about 15 seconds transmit on
channel 16 the safety call and message as follows -
“Securité, Securité, Securité”
“All stations (or called station)” repeated three times
“This is (MMSI and name or callsign of own vessel)”
Repeat text of safety message.
Calling a coast radio station
Enter the MMSI of the station into the RD68, either manually
or from the directory. When the call is acknowledged, the
working channel for voice communication will be indicated
and the RD68 will automatically switch to that channel. Make
a voice call as normal.
Making an intership call
Enter the vessel’s MMSI into the RD68, either manually or
from the directory. Before sending the call, enter the inter-ship
channel to be used for subsequent communication. When the
alarm sounds on the called vessel, its operator should acknowl-
edge by DSC, then respond by voice on the selected channel.
If the MMSI number of the vessel is not known, call as now on
channel 16. If no response is received, call on channel 13. This
is the GMDSS bridge to bridge communication channel.
