4.6.18.5 Receiving a Group Call
When a Group Call is received, the DSC indicator flashes, Grp appears
on the 7-segment display, and the DSC Received Alert is sounded. On the
dot matrix display appears the message RECEIVED GRP CALL. If the
MMSI number exists in the list, the associated name is displayed. If no
match is found, the actual numeric value of the MMSI is displayed. You
are then prompted to press ENT to accept or CLR to log the call.
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 Group 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 key. Press PTT to transmit. If
PTT is not pressed within 5 seconds of the prompt appearing, the
transmission is done automatically. Pressing the PTT key causes the
channel to change to the communication channel.
If the CLR key is pressed, the alarm is turned off, the displays are cleared,
and the received contents are stored in the Log File. The radio then reverts
to the operation mode before receiving the Group Call.
