DSC self test
To run a control routine DSC self test, do as follows:
1. Press the soft key
SETUP
. If it is not in the display, press the soft key
MORE
until

appears.
2. Press the arrow soft key
or

3. Turn the selector wheel knob to select

. Press and turn the
selector wheel knob to select

.
The test will check the ability to encode/decode DSC signalling on RF level.
The radio will automatically transmit a DSC safety test call to its own MMSI
number without enabling the transmitter power amplifier. In parallel the
radio decodes and compares the received call to be the same as the
transmitted.
The display shows the result of
the test.
4. Press the soft key
OK
to
acknowledge the test result and
resume normal operation.
Important
If the DSC loopback test fails, this indicates the DSC
functionality does not work correctly — including the ability to
send a DISTRESS message.
Contact your dealer immediately for further advice.
