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.
6.1 Arrival Alarm, Anchor Watch Alarm
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.
