Receiving an Individual call

When the transceiver is not used for traffic, scanning should be activated to keep watch on
one or more DSC frequencies used for public correspondence and general ship-to-ship
communication.
Reception of an individual routine call addressed to the ship is indicated by a sound signal
which continues until the call is acted upon. The call alarm sound level setting can be
changed, see the Menu tree.

The call should be answered by sending a DSC Acknowledgement within 4½ minutes.
LIFT HANDSET TO ACKNOWLEDGE and ACK is shown if SSB telephony and legal
frequencies are indicated in the call. Lifting the handset or pressing the softkey in this case
will initiate transmission of an acknowledgement containing the mode and frequencies from
the received call.
