Distress alert received on HF band

flashes in red. The icon for DISTRESS receiving (
) appears in the tab area and the 
pop-up message "DISTRESS ALERT message received! [CANCEL]: Stop alarm" ap-
pears on the screen. Press the CANCEL key to silence the audio alarm and stop the

knowledge call from a coast station, which usually takes about five minutes from the 
time of receiving a distress alert, follow the flow chart in this section to determine your
