DSC
routine
testing Check the DSC function regularly. Verify the
complete DSC installation, with antennas, by
transmitting a Safety Test call to another
station (coast or ship). The test call is
generated using the DSC call flow via menu
CALL.
The call should normally be replied by the
receiving station without questioning. The
default configuration of a DSC VHF radio is
auto-acknowledgement of any received
Safety test call requests. If a ship is equipped
with multiple radios a second radio can be
the station to check up against. The
transmitting radio will not receive its own
transmitted calls.
If there is only a single radio on a vessel, a
facility is built into the unit where the DSC
engine can be verified using a test call that is
internally looped without activating the radio
transmitter PA. The test is executed via menu
SETUP, DSC SETUP. The call sequence that is
verified, is an Individual Safety Test Call
directed to own MMSI. The test status is read
in the display.
