NOTES:
All of the alarm messages always appear on all of the echo
sounder’s screens. You won’t miss any alarms while displaying echo
sounding data, and you never have to press any keys to view the
current alarms (although you must press

to clear alarms that
don’t automatically clear).
The

whenever you press either of these keys, the corresponding

waypoints will be displayed automatically
on the echo sounder’s picture, as well as on the
