I cannot get the distress button and/or the DSC feature to work. What is wrong?
You first need to program an MMSI number (Maritime Mobile Service Identity number) into your marine radio. The MMSI number is issued by a government-sanctioned organization. You can get an MMSI number from several sources: • Industry Canada Toll Free: 1-800-667-3780 Enter the MMSI number into your radio as follows: (See page 48 of the MRF55 manual, or page 50 of the MRF75 manual) • Press and hold the CALL/SET button until the radio enters the setup menu. • Press the channel buttons to get to USER MMSI, then press CALL/SET. • Now enter the 9-digit MMSI number. Use the channel buttons to select the number, then press CALL/SET to move to the next digit. You can press the HI/LO button to backspace or press the 16/9 button to abort the whole process. • After entering the last digit, press and hold CALL/SET until you pop back to the setup menu. Then press the 16/9 button to exit the setup menu. Now that you have entered the MMSI number, both DSC and the distress button will be active.
