Alarm Tab
The Alarm tab allows you to define the alarm settings. The Alarm
tab is divided into three sub tabs: System alarms, Nav alarms, and
Sonar alarms.
System Sub Tab
• Clock—provides an alarm for the system clock. Enter a
time in the time field, and turn the alarm on and off from
the control field menu. Remember to enter alarm times in
the same time format (UTC or local) you are using for your
system. The unit must be on for the clock alarm to work.
• Battery—sets an alarm to sound when the power is reaching
a critical state of discharge.
• GPS Accuracy—the accuracy alarm sounds when the GPS
position accuracy falls outside the user-set value.
Nav Sub Tab
• Anchor Drag—sets an alarm to sound when you have
exceeded a specified drift distance. Enter a value in the
distance field, and use the control field to turn the alarm on
and off.
