4.5. DIGITAL SELECTIVE CALLING (DSC)
Cautions in operating KEY
As the test of this function may cause huge damages to near-going vessels
and search & rescue authorities, therefore, the test MUST NOT be made at
all times. Once the call is operated, an alarm will come out from the speaker
and the message will be transmitted if the hand is off from the switch for 5
through 10 seconds. It is possible to stop the mistaken launch if the hand is
off from the [DISTRESS] KEY within 5 seconds but it is not possible to stop if
any stop work is performed in the middle of the transmission as the signal
speed is so fast. In particular, much attention should be paid because the
whole message may be transmitted.
How to transmit Distress Call
Press
button for 3 seconds to transmit Distress Call message. The
Distress Call prioritizes all other performances and the alarm is output from
the speaker. And then non-modulated carrier will be followed after
transmission and the distress message will be automatically transmitted. The
message will be transmitted 5 times and then the transmission will be
repeated at the intervals of 3 minutes 30 seconds through 4 minutes 30
