The following fault warnings may be shown on the Information Display:
OFF COURSE
RESET ALARM
Course deviation is greater than selected off course alarm limit. Press the Alarm
button to cancel the alarm. The alarm is automatically reset when the vessel is
back within the limit.
RUDDER FEEDBACK
FAIL!
Indicates that the autopilot is not reading rudder feedback signal. By pressing the
alarm reset button, the audible alarm will be reset and the autopilot will switch to
a simulated signal, instead of the real. This is indicated by a flashing * * SIM * *
on the information display. Repair actions should be taken when back in port.
NO RESPONSE
FROM RUDDER
If a rudder command is not executed, or the rudder moves in wrong direction, this
message will be shown on the display. The reason can be a malfunction of the
steering gear, or simply that the steering gear is not switched on.
NAVDATA NOT REC.

manual).

All three messages indicate problems with reading the signals from the navigation
receiver. If you are unable to cure the problem, the NAV-mode should not be used
before a Robertson dealer has been consulted.
These alarms will be given when the autopilot is unable to detect a proper signal
from the selected heading sensor. The reason can be a faulty sensor or wrong
selection of sensor (See “Type of Heading Sensor”, page 6-4).
DATA FAILURE
CHECK SETTINGS
If the autopilot should lose or read erratic data stored in the memory, this alarm
will be given, and the autopilot is simultaneously set to MANUAL-mode.
