Operating Your Radio Digital Select Calling (DSC) Setup 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 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 identifier 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 official 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. 38 English Operating Your Radio Digital Select Calling (DSC) Setup To Enter Your MMSI Number: 1.

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.
