E04819 Issue 1.0

When an acknowledgment is received from the rescue co-

ordination center, this will automatically cancel the Distress

Alert transmission. The subsequent rescue co-ordination will be

performed using the voice working channel (Ch16).

Warning If a DSC Distress Alert is sent accidentally, cancel

it immediately on the RS86/RS87 by pressing the

N/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) – Over.”

Do not simply cancel the DSC alert without ver-

bally canceling 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 4.11). 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.
