Canceling Depth Alarms
A depth alarm warning can be temporarily canceled by pressing
both L and M on the speedometer, simultaneously. After one
minute, the alarm will resume if the condition that caused the
alarm is not corrected. The operator can cancel the alarm as many
times as necessary, until the condition is corrected.
The depth alarm warning will replace any information on the LCD
screen. Canceling the alarm will restore the LCD to the original
display. If not already in the depth mode, this would be a good time
to switch to it (using M) in order to monitor water depth.
Depth Sounder Alarm Settings
The speedometer display must be in the depth display mode to
change settings. Use the M to scroll to the depth display.
To change the depth sounder alarm settings M must be held down
until the depth display changes to the alarm settings mode.
There are four menus in the alarm settings mode. Pressing and
releasing the mode switch quickly will cycle through the different
options.
Shallow Alarm
This alarm sounds when the water depth equals or is less than the
set value.
The display will show "S X.X" which is the current setting for the
Controls and Indicators
