CAUTION
Risk of data loss through shutdown of the compass / power-off condition
After a shutdown of the compasses main and backup power supplies it
cannot be guaranteed that all menu settings remain stored unchanged.
Always check that the alignment error correction value is noted correctly
in the setup tables, before switching-off the power supplies, see “Setup
and Configuration Tables” on page A-1 Appendix.
Always make sure to separately note the alignment error correction
value before switching-down the compass for maintenance or repair pur-
poses.
Note A visual inspection of cables and connectors of the gyrocompass should
be carried out regularly to detect any signs of damage or deterioration.
Note In case a „Speed Invalid“ alarm is triggered while the vessel is not in
motion or moving very slowly (e.g. when manoeuvring in harbour), this
is often caused by fast currents of fairway water increasing the - 5.0 kn
minimum speed default value.
In this case, the minimum speed value must be adjusted accordingly.
Note The access code for the setup menu to reset the gyrosphere operation
time counter is disclosed to authorized service personnel only and is not
described in this manual.
