Whenever power is applied the depth sounder is
active and water depth is displayed. If the sonar
signal does not show a bottom the display will
indicate "- -". This can occur if the water is aerated
or the maximum depth is exceeded.
Note: The maximum depth decreases as boat speed
increases.

Alarms

Two types of alarms can be set; the Deep Alarm
and the Shallow Alarm. The Deep Alarm can be
set as high as 184 metres (605 feet) while the
Shallow Alarm can be set as low as 0.3 metre (1
foot).
Whenever the water depth is greater than the
Deep Alarm setting and the alarm is enabled an
alarm will sound. The alarm repeats two short
beeps and alternates DAL and the water depth
on the display.
Whenever the water depth is less than the
Shallow Alarm setting and the alarm is enabled
an alarm will sound. The alarm repeats a single
long beep and alternates SAL and the water
depth on the display.
