IMPORTANT ALARM NOTES:

Anchor Alarm - The anchor alarm may be triggered even when you are sitting still. This usually happens when using small — less than

.05 mile — anchor alarm ranges.

Arrival Alarm - If the arrival alarm distance is set to a small num- ber, the unit may not show navigation data to the next waypoint af- ter you arrive at the first one. That occurs when you are not able to come close enough to the first waypoint to trip the arrival alarm.
