3.5.26.3 Receiving an Individual Call
When an Individual Call is received, the DSC indicator flashes, Ind appears
on the 7-segment display, and the DSC Received Alert is sounded. On the
dot matrix display appears the message RECEIVED IND CALL along with
the type of call. There are three types of Individual calls: ROUTINE for
normal calls, SAFETY for advisory alerts, and URGENCY for assistance
when life is not in immediate danger. If the MMSI number exists in the
Phonebook list, the associated name is also displayed. If no match is
found, the actual numeric value of the MMSI is displayed. Lastly appears
a prompt to press ENT to accept or CLR to log the call. This sequence
scrolls every second.
Until either the ENT key or the CLR key are pressed, the prompt is flashed
at 1-second intervals and is accompanied by an alarm for up to 3 minutes.
If neither ENT nor CLR are pressed during these 3 minutes, the radio
reverts to the operation mode before receiving the Individual Call. The
DSC indicator continues to be flashed on the LCD display until the contents
of the log files can be confirmed.
If ENT is pressed, the alarm is turned off, and a new prompt appears on the
display, instructing you to press the PTT switch. Press PTT to transmit an
acknowledgment (ACK). If PTT is not pressed within 5 seconds of the
prompt appearing, the transmission is done automatically. Pressing PTT
switches the radio to the communication channel.
