PLUS functions

General information
Alarm on = minute sign ( ´ ) displayed above the last depth digit in the sub-function.
Alarm off = no minute sign ( ´ ) displayed.
The alarms will be triggered, if the actual depth becomes less (shallow alarm), or more
(depth alarm), than the set depth value.
The alarm is audible (signal) and visual (main and sub-function flashes).
When a triggered alarm has been silenced, it will only be triggered again if the selected
depth value differs by +/-2m (6 ft)
If a different page than DEPTH is shown when the alarm is triggered, the set alarm
function will automatically be shown flashing, until you silence or turn off the alarm.
The instrument will then automatically return to the previous page.
Loss of signal. If there are no depth echoes for 3 seconds, the display indicates 3
dotted lines ( --- ) until a new echo is received.
