This feature allows the user to contact another vessel with a DSC radio. This feature is
similar to calling a vessel on CH16 and requesting to go to another channel.
Using the Individual Calling directory
To use this method the CPV550 must be pre-programmed with MMSI numbers of vessels
you wish to call (similar to programming in telephone numbers into a cell phone. Refer to

signal is not received, the transceiver will transmit again.
6. After the second INDIVIDUAL CALL is transmitted, if the reply signal
is not received, the display will be as shown in the illustration on the
