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 benets 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.
These procedures use the Settings menu. Refer to page 28 for information on entering
and exiting the Settings menu.
User MMSI Number
The nine (9) digit MMSI number, similar to a telephone number, is a unique identier
for a vessel. DSC incorporates this number into every message that is Sent (Tx) or
Received (Rx). Enter the MMSI number as soon as you receive your MMSI number
from the issuing agency listed on page 9.
NOTE
The radio does not operate in the DSC mode until an ofcial MMSI number is
entered. An error tone will sound when attempting to operate in the DSC mode
without an MMSI number.
NOTE
An MMSI number can only be entered one time. To enter a new MMSI number,
please contact Cobra customer service.
To Enter Your MMSI Number:
1. Enter the Settings menu and scroll to DSC SETUP
with the Up/Down soft keys or the channel Up/Down
buttons.
2. Press the ENTR soft key and scroll to RADIO MMSI
ENTRY with the Up/Down soft keys or the channel Up/
Down buttons.
3. Press the ENTR soft key . The blinking cursor will appear
at the rst digit under RADIO MMSI ENTRY.
4. Use the Up/Down soft keys or the channel Up/Down
buttons to scroll through the number list to the rst digit
of your number.
5. Press the ENTR soft key to select the digit and the
blinking cursor will move to the next digit of the number.
6. Repeat steps 3 and 4 until all nine (9) digits of your
MMSI number are entered.
7. Check that you have entered the number correctly. The
radio will ask you to re-enter your number to conrm.
8. Press ENTR soft key to save the MMSI number and the
radio will return to the DSC SETUP MENU.
NOTE
After the MMSI number has been entered, the RADIO
MMSI ENTRY menu option will move to the bottom
of the DSC SETUP MENU. This is done because the
MMSI entry is entered only once.
If You Incorrectly Enter Your MMSI Number
YOU CAN DO THIS ONLY ONCE! An attempt to enter an MMSI number again will result
in an error message as shown.
Pressing the EXIT soft key from the error message will return the radio to the DSC
SETUP MENU.
Once the error message appears, the radio will still operate in all non-DSC modes.
But you will have to contact Cobra
®
Electronics (see product service on page 84 for
details) for reset before you can enter a new MMSI number into the radio.
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.
