Drift Alarm 

Drift Alarm sounds when the boat has exceeded the distance from the

boat’s anchored position, based on the menu setting. Drift Alarm allows you to set the size of a perimeter
around the boat’s anchored position; if the anchored boat drifts outside of that perimeter, the Drift Alarm
will sound. 

To change the Drift Alarm setting:

1.  Highlight Drift Alarm on the Alarms main menu.

2.  Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Drift Alarm setting. (Off, 25 to

3000 feet, 10 to 1000 meters [International models only], Default = Off)
