Digital Selective Calling Placing All-Ships Calls All-ships calls are transmitted to all stations within receiving distance of your radio. You can make two types of all-ships calls: • Safety calls are used to broadcast significant navigational or weather-related information. • Urgency calls are used to communicate situations about the safety of a vessel or person when danger is not imminent. Discerning whether a situation warrants a distress call or an urgency call is the responsibility of the captain. To place an all-ships call: 1. Press the DSC key. 2. Select ALL SHIPS. 3. Select SAFETY or URGENCY to indicate the reason for your call. 4. Select CALL. The radio transmits the call on Channel 70 and then automatically switches to Channel 16. Placing Position Request Calls Position data received from stations that respond to position request calls is sent over the NMEA network, so that you can track the vessels on your Garmin chartplotter, for example. For more information on NMEA 0183 and NMEA 2000, see page 29. 1. Press the DSC key. 2. Select POS. REQUEST. 3. Select from the following options to select the place from which the MMSI number is retrieved: • MANUAL-a screen is displayed that gives you the ability to enter the MMSI number manually. Select a number and move to the next character. When you have entered the correct MMSI number, select ACCEPT. • DIRECTORY-the directory is displayed. Select an entry. 4. Select ACCEPT when you have entered your MMSI number. 5. Select CALL. The radio transmits the call on Channel 70, and then switches to your current working channel. The screen displays "POS REQUEST WAITING FOR ACKNOWLEDGE". 20 VHF 100/200 Series Owner's Manual
