User's Manual

When an acknowledgement is received from the Rescue Co-
ordination Centre, this will automatically cancel the Distress
Alert transmission. The subsequent rescue co-ordination will
be performed using the voice working channel (Ch 16).
WARNING If a DSC distress alert is sent accidentally, cancel it immediately
on the RD87 by pressing the On/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.
4.3 Receiving a call
4.3.1 Individual Routine call
If an Individual Routine call is received, the radio will sound
an incoming call alarm.
The display will flash between displaying “Call From”, the
caller’s MMSI and the specified working channel (Fig 4.10). If
the caller’s MMSI is stored in the MMSI directory (see section
5.2), then the display will show the name stored instead of the
MMSI number.
