gyrocompass.

case the fan is found in improper condition.
A default exchange of the fan is recommended in a three years interval.

Risk of damage through overheating
A polluted or clogged air inlet grill located at the back side of the compass
housing will decrease the functionality of the fan and cause overheating
of the gyrocompass.
Always maintain the required distances around the compass housing to
enable sufficient air supply and full fan functionality.
Make sure to regularly clean the air inlet grill from dust and dirt and check
the fan functionality to avoid overheating.
