The AC supply voltage (ships mains) may drop out.
This leads to a restart of the gyrocompass and a new settling
stage.
The heading information during this settling stage has a
reduced accuracy (see section 2.1.2).
Therefore a continuously supply with 24VDC should be gua-
rantied.
There is a reduced accuracy of the compass during the set-
tling stage.
The compass shows required accuracy after ending of the
settling stage (appr. 4 hours after switching ON).
It is strongly recommended to observe (to read) all manuals
within a Compass STD 22 application.
