44 RayChart 620
4.6 Alarms and Timers
The RayChart 620 reports the following alarms:
Alarm Indicates:
Arrival Your vessel has arrived at the active waypoint: it has
either broken the arrival circle (the radius of which is set
in Set Up) or, for an intermediate waypoint, is
perpendicular to the route leg through that waypoint.
Off course Your vessel has exceeded the specified 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 RayChart is no longer receiving position
information from GPS, dGPS or Loran.
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
➤
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 RayChart except for the Arrival Alarm. If you
press a key, or after 7 seconds, the RayChart starts tracking to the next
waypoint. Alternatively, if you have arrived at the last waypoint in the
route, the RayChart stops tracking.
Note: The RayChart also repeats any SeaTalk alarms it receives, such
as Depth and Wind alarms.
