4.2 Receiving a Distress Alert
When you receive a distress alert from a ship in distress, the audio alarm sounds and the
message "Distress call received." appears on the display. Press the [CANCEL] key to
silence the audio alarm. Wait for the distress acknowledge call from a coast station. If you
do not receive the distress acknowledge call from a coast station, which usually takes
about five minutes from the time of reception of a distress alert, follow the appropriate flow
chart in this section to determine your course of action.
Note 1: An asterisk (*) appearing in a distress alert call indicates error at asterisk location.
Note 2: If the Telex Distress Alert Button IC-302-DSC is connected, the aural alarm
sounds and the IC-302-DSC’s alarm lamp lights in red when a distress alert is
received. To silence the aural alarm, press the [ALARM STOP] key.
Russian version
If another distress alert or urgent call is received just after pressing the [CALL] key (for
distress alert relay and distress acknowledgement), the most recently received call has
priority.
