2.1 Operating Conditions
The permitted ambient temperature for the operation of the gyrocompass sys-
tem is -10 – +55 °C.
When the ambient temperature at the gyrocompass’ location falls below -10 °C
while the compass is in operation or when the ambient temperature falls below
0°C while the compass is not in operation, the gyrosphere container must be re-
moved from the compass housing and stored in a place where the ambient
temperature will not fall below 0 °C.
If no storage place is available where the ambient temperature will not fall be-
low 0 °C, the gyrosphere must be removed from the gyrosphere container to
prevent possible damage by frozen supporting fluid.
