A visual inspection of cables and connectors of the gyrocompass should
be carried out regularly to detect any signs of damage or deterioration.
kçíÉ
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.
kçíÉ
