ALARMS

There are six conditions that can trigger audible and visual alarms in this unit: Arrival alarm, Anchor Watch alarm, Cross-track Error (XTE) alarm, Border alarm, and Ship’s Speed alarm (two types).

Up to three alarms can be actuated. When an alarm setting is breached, the audible alarm sounds and the alarm icon appears at the bottom right-hand corner of the display.

Note: The alarms are useful for alerting you to possibly dangerous situations. However, the captain is always responsible for the safe operation of his ship. FURUNO Electric Company will assume no responsibility for any damages associated with the use of the alarms.

Arrival alarm

The arrival alarm warns you your ship is approaching a destination waypoint. The area that defines an arrival zone is that of a circle which you approach from outside the circle. The alarm will be re- leased if your ship enters into the circle.
