13.1.3 Cancelling a Distress Alert
If a DSC Distress Alert is sent accidentally, cancel it immediate-
ly on the RS81/RS82 by pressing the O
N/C button to prevent
repeats, then make the following announcement on channel 16:
“This is (name of vessel or call sign, MMSI)”
“Cancel DSC Alert sent (date & time UTC)”
“Over.”
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.
13.1.4 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)” – repeat three times
“This is (MMSI and name or call sign of own vessel)” –
repeat text of safety message.
“Over.”
13.1.5 Calling a coast radio station
Enter the MMSI number of the station into the RS82, either
manually or from the directory. When the call is acknowledged,
the working channel for voice communication will be indicated
and the RS82 will automatically switch to that channel. Make a
voice call as normal.
13.1.6 Making an intership call
Enter the vessel’s MMSI into the RS82, either manually or from
the directory. Before sending the call, enter the intership chan-
nel to be used for subsequent communication. When the alarm
sounds on the called vessel, its operator should acknowledge
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.
NOTE If no response is received, call on channel 13 (this is the GMDSS
bridge-to-bridge communication channel).
13.2 NMEA sentences received
The following NMEA0183 sentences are processed by the RS82,
in order to transmit the boat’s position if a Distress Alert is ini-
tiated: NMEA0183 version 2.0 and 3.0 – GGA, GLL, RMC, ZDA.
