62 Ray49 Marine VHF Radio
Receiving a Distress Call
The Ray49 receives distress messages sent by another vessel and/or
acknowledgments (ACK) sent by a coast station to another vessel in distress. The
radio also receives distress relays.
Note:
Class “D” DSC radios such as the Ray49 are forbidden by law from automatically
acknowledging or relaying DSC distress calls. Upon receiving a distress call, you may hail
the vessel in distress on channel 16 and standby to lend assistance if requested.
When a Distress Call is received, the Ray49 automatically tunes to channel 16 and
sounds the Distress Alarm Tone. (If you have disabled automatic channel
changing, as described on page 84, you are first prompted whether to accept the
call.)
Two alternating screens appear in the display. When position data and time is
included within the signal, it is displayed on the first screen in the text area of the
LCD. The second screen shows the nature of the distress and time it was sent.
The 2 alternating pages of data are recorded in the Distress Log. The envelope
icon (
) blinks until you accept the call, reject the call, or open the resulting
unread message stored in the Log. See page “Received Calls (Logs)“ on page 79.
To mute the alert tone:
Press
CLR/WX .
To ignore the Distress Call:
Press CLR/WX a second time. The envelope icon disappears, the call is interrupted
and the normal screen appears on the LCD.

1. Press the CH/OK knob. The alert tone is muted, the envelope icon disappears
and the radio switches to channel 16.
2. Press CH/OK again to confirm the channel change. The radio returns to
standby mode. Press PTT to communicate on channel 16.
To accept a Distress Call when Auto Channel Change is ON
Press CH/OK . The alert tone is muted, the envelope icon disappears and the radio
automatically switches to channel 16. Press PTT to communicate.
