When You Receive a Distress Signal

When you receive a distress signal, the related DISTRESS indicator flashes and the two-tone
alarm sounds. The volume of the alarm gets louder after five seconds.
To stop the audio alarm, push the MUTE ALARM button. The related DISTRESS indicator then
illuminates. The indicator turns off when the distress signal is stopped.

How to Send a Distress Signal

If YOUR ship is in distress, send a distress signal and do distress communications with a coast
station by radiocommunications. The IC-350 has five distress buttons. Use the No.1 VHF button
(leftmost DISTRESS button) to send a distress signal in normal use.

To send a distress signal, open the cover of the correct DISTRESS button and push the button
more than four seconds. In the first three seconds, the button flashes and the speaker releases
three beeps. The button then illuminates and the distress signal is sent. Do distress communica-
tions with a coast station by the same communications equipment used to send the distress sig-
nal.
If you release a DISTRESS button within three seconds after you pressed the button, the distress
signal is not sent. If you accidentally sent a distress signal, contact a coast station to report acci-
dental distress transmission. Contact the coast station by the same communications equipment
used to send the distress signal.
If a DISTRESS button does not flash when the button is pushed more than four seconds, the re-
lated communications equipment is turned off. If a DISTRESS button does not illuminate, related
communications equipment is not connected, and the distress signal is not sent.
If you accidentally sent the distress signal with the MF/HF DISTRESS button and powered off the
SSB radiotelephone after realizing the mis-transmission, the lamp in the DISTRESS button con-
tinues to illuminate. If this happens, long-push the MUTE ALARM button to restore normal oper-
ation.
Note: If you accidentally sent the distress signal, refer to the operator's manual of the radiocom-
munications equipment for the procedure to cancel the distress signal.
