4.6 Alarms and Timers
The chartplotter reports the following alarms:
Alarm
Indicates:
Arrival
Your vessel has arrived at the active waypoint; it has either:
entered the arrival circle (the radius of which is set in Set Up)
or, has passed the perpendicular to the route leg through the
waypoint.
Off course
Your vessel has exceeded the specified cross track error
distance (set in Set Up) from the active route leg.
Anchor
Your vessel has moved from its anchor position by more than
the distance specified in Set Up.
Countdown
The countdown timer has reached zero.
Clock
The time matches the alarm time set in Set Up.
Danger zone
Your vessel has entered the danger zone circle (the radius of
which is set in Set Up) for the danger mark ( ).
Fix status
The chartplotter is no longer receiving position information
from GPS, dGPS or other source.
The alarms are switched on or off, and the limits set, using the
ALARMS/TIMERS
option from the Set Up menu (see Chapter 6). This option also controls the
elapsed time counter, which displays the time elapsed since the last reset in the
cursor data box.
When an alarm is triggered, the alarm buzzer sounds and a window such as the
following is displayed:
D3832-1
Arrival Alarm
to 008WPT
Any key to CLEAR
➤
To silence the alarm and clear the message, press any key. Alternatively, wait 7
seconds for the alarm to time out.
No action is taken by the chartplotter except for the Arrival Alarm. If you press
a key, or after 7 seconds, the next waypoint becomes active. Alternatively, if
you have arrived at the last waypoint in the route, the chartplotter stops
navigating.
Note: The chartplotter also repeats any SeaTalk alarms it receives, such as
Depth and Wind alarms.
