3 Warning signals
All warnings (see also section 3.1) are indicated on the compass by means of a flashing
decimal point.
It is not necessary to acknowledge the warning on the compass.
The warning (the flashing decimal point) remains until the fault that caused the warning
has been corrected.
The course indicated on the digital display unit is not affected by the warning.
EXCEPT for warning 5 “Voltage cut-off” (see section 3.1)
When a warning occurs the decimal point
flashes on the compass’s digital display unit
for as long as the warning is pending.

on the digital display unit
If warnings occur, the operation of the gyro compass is not restricted. If the
cause of the problem is rectified quickly, it is possible to prevent the
equipment from breaking down.
The procedures indicated here to temporarily remove the warning signal
in some degree restrict the compass’s operational safety (if the door is
open, the system’s electrical operational security, spray protection and
electromagnetic compatibility are all restricted).
