Receiving DSC Calls
Your SX 35 DSC can receive four types of DSC calls; Distress, All Ship’s,
Individual, and Group. Except for Distress, each call type is subdivided
into one or more priorities.
All Ship’s type receives the following priorities: Distress ACK, Distress Re-
lay, Urgency, and Safety.
Individual type receives the following priorities: Safety and Routine.
Group type receives one priority: Routine.
When your SX 35 DSC receives a DSC call from another vessel or a coast
station, an alert sounds and a Call Received screen appears in the display.
The Call Received screen identifies the time of a call, the caller, the type and
the priority of a call. Also, a number appears in the screen indicating the
number of calls in the log. The call log holds thirty two entries.
