triggered, it can be silenced by pressing the EXIT key.

functioning GPS receiver is attached to the Matrix unit.
NOTE: When an alarm is triggered, you can silence it by
pressing any key. Once you silence an Off Course or Drift

outside the set alarm limits. These alarms will turn off
automatically if the boat moves back inside the limit.

boat drifts outside of that perimeter, the Drift Alarm
will sound. This setting also changes the display size
of the Drift Alarm perimeter that surrounds the
boat’s current position. (Off, 30 to 3000 feet in
increments of 30, 10 to 1000 meters* in increments
of 10, Default = Off).
