Alarm Reporting
The chartplotter reports the following alarms, that are set using the ALARMS
key:
Alarm Indicates:
Arrival Your vessel has arrived at the active waypoint: it has either
reached the arrival circle (the radius of which is specified) or,
has reached its closest point of approach (defined by a line
passing through the waypoint and perpendicular to the route
leg).
Off Track Your vessel has exceeded the specified distance (maximum
cross track error) from the active route leg.
Anchor Your vessel has drifted from its anchor position (set when the
alarm was turned on) by more than the specified distance.
Countdown The countdown timer has reached zero.
Alarm Clock The time matches the specified alarm time.
The alarms are switched on or off, and the limits set, using the Alarms Set Up
menu, accessed from the
ALARMS key.
When an alarm is triggered, the alarm buzzer sounds and a pop-up window
describing the alarm is displayed.
➤ To silence the alarm and clear the message, press any key.
If the alarm was generated by the chartplotter, the appropriate action is taken.
For example, following an arrival alarm, the next route leg is activated.
If an anchor alarm is silenced, but the alarm condition perstists, the alarm is
repeated every 30 seconds.
External Alarms
All SeaTalk system alarms (except autopilot alarms) are received and
displayed on the chartplotter. You can silence these alarms by pressing any
