But, that is not the only advantage of DSC equipped radios. Those radios are set up
to interface with GPS and to automate many of the operations involved in sending
and receiving messages. That results in more compact and accurate messages and
less congestion of the airwaves.
Notice Caution
The price of these benefits to the user is the time it takes to do the required set-up
to make the DSC features work. A little time spent when your radio is new will pay
dividends over its life.
This radio follows Class D DSC with a dedicated Channel 70 receiver.

6. Check that you have entered the number correctly.
7. Press the Call/Set button.
8. Repeat steps 3 through 6 to verify the number by
re-entering it.
9. Press and hold the Call/Set button to accept the
number and return to the Settings menu.
If You Incorrectly Enter Your MMSI Number
You CANNOT re-enter your number. A second attempt to enter
an MMSI number will result in an error message as shown.
Pressing the Call/Set button from the error message will
return the radio to the Settings menu.
Once the error message appears, the radio will still operate
in all non-DSC modes. But you will have to return the radio
to your local dealer for reset before you can enter your
MMSI number to use the radio in DSC mode.
Because the MMSI number is so important to DSC
operation, this limitation is imposed on all DSC capable
radios to prevent constant changes and the potential
introduction of errors in the process. If, for any reason,
it is necessary to change the MMSI number in the radio,
you can return it to your local dealer for reset.
