ALARM MUTE
When eitherthe shallow or
deep
alarm is
triggered, an audio tone
sounds.
A different tone sounds
forthe shallowthan the
deep alarm,
thus
letting
you
know which alarm is sounding without
looking at the unit. Once a
depth
alarm is
triggered,
it
keeps sounding until
you change depth.
For
example,
if the
shallow alarm is set to 10
feet, and you move into and stay
in water
that's five feet deep, you're going to get tired of listening to the alarm
beeping all the time.
To keep
this situation from
happening, a new label appears
on the sonar
whenever a
depth alarm sounds. This label
says "Silence Alarm".
This turns the alarm's sound off until it's triggered again.
The flashing cross is your
present position.
The solid line
is
your track,
or
path you have
just
traveled. The
large square
is a
compass
rose marked with
North, South, East, and West.
The
square's height and width
shows at the bottom of the
screen.This isthedistancefrom
one side to the other and from
the top to the bottom. Your
present position is shown atthe
top
of the screen.
