Normal DSC Calls
Your SX 35 DSC can transmit 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 transmits two priorities: Urgency and Safety.
Individual type transmits one priority: Routine.
Group type transmits one priority: Routine.
A normal DSC call may be originated from your vessel to another DSC
equipped vessel or to a coast station, or you may reply to a DSC call sent by
another vessel or a coast station. Outgoing calls are made either by select-
ing a vessel or station name from your directory or by manually entering
the vessel or station MMSID number.
Replies to any incoming call type can be made directly from the call log.
The call log (LAST CALL) holds thirty two entries and the last call received
is on top of the list. If the call log is full, the oldest entry is lost.
Individual DSC Call
Individual calls can be made to another vessel or to a coast station. It is
important to be able to differentiate between the two. When calling another
vessel, the communication channel is specified in the call by the calling ves-
sel. If communicating with a coast station, it is the coast station in its ac-
knowledgment, that determines the channel. Your SX 35 DSC transceiver
transmits Routine individual calls, but receives both Routine and Safety in-
dividual calls.
Directory Call
Directory calls are made by selecting a vessel or station name from the call-
ing directory. The calling directory holds thirty two of your previously
entered names that you routinely contact during normal boating activities.
