Depth Alarms
The depth alarms are triggered only by the bottom signal. No other
echoes will activate these alarms. The depth alarms consist of a shallow
and a deep alarm. The shallow alarm sounds an alarm tone when the
bottom goes shallower than the alarm's setting. The deep alarm sounds
a tone when the bottom goes deeper than its setting. Both alarms adjust
the same way, although through different menus.
