Using Digital Selective Calling (DSC) Features Suppose you are coordinating safety for a sailboat race. Before the race starts, you instruct all the racers to enter your group MMSI number into their radios. During the race: • Throughout the race, you use group calling to update the racers on the time, race status, and any course corrections. • A power boat full of spectators comes a little too close to the race path. You use individual calling to contact the power boat and advise them to stay clear of the race. • You see a rowboat entering the area, but since it doesn't have a radio, you can't communicate with the rowboat. You use all ships calling to alert all the other boats in the area of the possible danger. Calling a single station (Individual Call) To call a single station with DSC, follow the steps below: 1. Press the MENU-PA button to display the menu. 2. Choose the DSC Call sub-menu, then select Individual. 3. The radio displays the names listed in your directory; use CHANNEL UP and CHANNEL DOWN buttons to highlight the directory entry you want to call and press the SELECT-1W/25W button. If you want to call a station that is not in your directory, select Manual. The radio prompts you to enter the MMSI number you want to call. Enter the MMSI number the same way you enter directory entries (see page 26) Enter all nine digits and press the SELECT-1w/25w button. 4. The radio prompts you to select a response channel. Use CHANNEL UP and CHANNEL DOWN buttons to scroll through the available channels. When you reach the channel you want to use for a response, press the SELECT-1W/25W button. 5. The radio displays the MMSI number you are about to call and asks you to confirm. If you want to call the displayed MMSI number, select Send. To cancel the call, select Cancel. 6. The radio automatically switches to channel 70 to transmit the call request. E-31
