A hailer horn allows you to make on-boat or ship-to-shore announcements, and allows two-way communications between connected radios.

    Entering Your MMSI Number NOTICE You can enter your MMSI number only once. If you must change your MMSI number after entering it, you must take your radio to your Garmin dealer for reprogramming. ® The Mobile Marine Safety Identity (MMSI) number is a nine-digit code that acts as a DSC self-identification number, and it is required to use the DSC capabilities of your radio.

  • Page 15: Sending An Undesignated Distress Call

    Sending an Undesignated Distress Call When you send an undesignated distress call, the nature of your emergency is not transmitted to the receiving stations. Sending an undesignated distress call is a faster procedure that can save you time during an emergency.

  • Page 16: Stopping Automatic Retransmission Of Distress Calls

    Stopping Automatic Retransmission of Distress Calls Select CANCEL. The radio remains tuned to channel 16. NOTE: Selecting CANCEL ends the automatic repetition of the call, but does not communicate to other stations that you no longer have an emergency. If you no longer have an emergency, you should revoke the distress call (Revoking a Distress Call, page 12).

  • Page 17: Placing Group Calls

  • Page 18: Receiving Calls

    Receiving Calls Receiving Distress Calls and Distress Relay Calls When receiving a distress call or a distress relay call, DISTRESS or DISTR RELAY, and information about the call, such as MMSI number and the nature of the distress, appear on the radio screen. A distress call is sent from a vessel in need of assistance, and a distress relay call is sent from either another vessel or a station on behalf of a vessel in need of assistance.

  • Page 19: Receiving Position Requests

    When you enable position tracking, the radio uses interval-based position requests to track up to three vessels. Your radio transmits received position data over the NMEA network, and you can track the vessels using your Garmin chartplotter (Configuring DSC NMEA Transmissions, page 21).

  • Page 20: Viewing And Deactivating Vessels On The Position Tracking List

    Position-Tracking Polling Interval Sequence Regulations allow transmission of one position-request call every five minutes. When tracking more than one vessel, the radio alternates calling each vessel in the list at five-minute intervals. If a vessel does not respond to five consecutive position-request calls, the radio removes the vessel from the position-tracking list. You can use this table to better understand how the time interval is applied to the vessels in the position- tracking list.

  • Page 21: Call Log

    Call Log When the radio receives a DSC call, it records the date and time, calling station, and type of call in the call log. The radio also records the latitude and longitude of the calling station if that data is transmitted with the call. DSC calls are logged as distress, position, or other calls.
