ALARMS
The
X-40 has two
different
alarms,
a zone

digital
depth
alarm. The
zone alarm consists of
a bar that
displays
on the left side of
the
screen. The
alarm sounds an
alert whenever the
X-40 detects an echo
inside the
boundaries of the
zone bar.
The
depth
alarm has
userselectable
upperand
lowerlimits. Unlike
the zone
alarm,
this
alarm
only
sounds on the bottom
signal.
It alarms with
a
high pitched
tone when the
bottom echo is detected
at or shallower

sounds with a low
pitched
tone when the

echo is
detected at or
deeper
than the
alarm's lower limit.
