Raymarine autopilot control unit - Manual (Page 48)

Chapter 3: Advanced Operation 31
• Track mode is engaged and the position transducer (GPS, Loran,
Decca) is receiving a low strength signal – this will clear as soon as
the signal strength improves.
• Wind mode is engaged and the autopilot has not received wind
angle data for 30 seconds.
The autopilot stops adjusting the locked heading as soon as data is lost.
Waypoint Advance
NEXT WPT
The waypoint advance alarm sounds whenever the target waypoint
number changes, which occurs in the following circumstances:
• Automatic acquisition is selected by pressing track from Auto
mode
• Waypoint arrival. Vessel arrives at the target waypoint and moves
onto the next waypoint in the route.
• Waypoint advance is requested by pressing track for 1 second in
Track mode (SeaTalk Navigators only).
When the alarm sounds, the pilot continues on its current heading, but
displays the bearing to the next waypoint and the direction in which the
boat will turn to take up that bearing.
Check that it is safe to turn onto the new track, and press track to
accept the waypoint advance.
To cancel the alarm without accepting the waypoint advance, press
standby to return to hand steering, or auto to return to Auto.
Note: The waypoint advance will only operate on pilots receiving
valid bearing to waypoint and waypoint number information.
Low Battery
LOW alternating with BATTERY
The Low Battery alarm sounds when the supply voltage drops below
acceptable limits.
Press standby to clear the alarm and return to hand steering.
Start the engine to recharge the battery.
