When a distress alert is received, the BAM alert is displayed. ENT button is pressed to 
close the BAM alert display and information such as the ID number of the ship in distress 
and the stage of the distress event are displayed.   
If the equipment is not used, i.e. there is no active procedure at that time, a distress and safety frequency is 
set and the ALM lamp starts blinking, and an alert sound gradually grows louder.
