DSC Set-Up
•
Digital Selective Calling — DSC — employs digital RF signals which tend to carry
further and be less susceptible to distortion from noise and atmospheric conditions
than analog ones. The result is greater range and more reliable message delivery
per watt of output power.
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.
The price of these benefits to the user is the time it takes to do the set-up needed
to make the DSC features work. A little time spent when your radio is new will pay
dividends over its life.
These procedures use the
Settings menu. Refer to page 38 for information on
entering and exiting the
Settings menu.
User MMSI Number
This nine (9) digit number is similar to a telephone number in that it is a unique
identifier for you and your vessel. DSC uses this number in every message it
sends and receives. That is why your radio will not operate in the
DSC mode
until you enter your MMSI number. You should enter it as soon as you receive
it from one of the issuing agencies listed on page 9.
To Enter Your MMSI Number:
1.
Enter the Settings menu and scroll to USER MMSI
with the Up/Down buttons.
2. Press the Call/Set button and the blinking cursor will
appear at the first digit under
USER MMSI ID ENTRY.
3. Use the Up/Down buttons to scroll through the number
list to that digit of your number.
4. Press the Call/Set button to select the digit and the
blinking cursor will move to the next digit of the number.
5. Repeat steps 3 and 4 until all nine (9) digits of your
MMSI number are entered.
6. Check that you have entered the number correctly.
7. Press and hold the Call/Set button to return to the
Settings menu.
If You Incorrectly Enter Your MMSI Number
You can repeat steps 1 through 7 to correct it. HOWEVER,
YOU CAN DO THIS ONLY ONCE! A third 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 it to Cobra
®
Electronics (see Product Service
on page 77 for details) for reset before you can enter
your MMSI number and use the radio in
DSC mode.
