cally. The unit now displays the water depth below keel (4.6 m in the ex-

Setting and activating the shallow water alarm

In unsafe depths and in waters with unknown depths the alarm will warn
you in time to avoid shallows and to prevent boat damages. The alarm
setting range is 0 m to 120 m (0 to 396 feet).
The alarm can be switched off or on by double activation of the pushbut-
ton when the display shows the current depth. The display shows the
alarm threshold (0.0 m in the example) when the alarm is switched on.
Set the desired alarm threshold by pressing the pushbutton. Up to 10 m
(32 feet) the value increments by 0.1 m (1 foot), up to 120 m (396 feet)
by 1.0 m (3...4 feet) per button activation. Continuous incrementation is
obtained by keeping the pushbutton pressed.
After about 5 seconds after setting of the alarm threshold (0.9 m in the
example) the display shows the current depth (2.7 m in the example) ,
and the set value is stored.
A continuous alarm is sounded if the depth below keel is less than the
set alarm threshold (0.9 m in the example), and the flashing display shows
the current depth measurement (0.7 m in the example).
