1. Set the operational parameters in the Manual Settings menu to suit-
able values, see ”Manual Settings Menu” on page 2-10 for details.
Wherever possible, automatic data input should be selected in pref-
erence of manual input.
2. Enter the current date and time in the User Setup menu, see “User
Setup” on page 2-17 for details.
3. After configuration, undertake a function-check of the system with
all connected equipment in operation. Use the test mode in the Serv-
ice Setup 1. See ”TEST MODE” on page 8-15
to check the heading
output to serial and 6 step/° repeaters and the analogue rate of turn
output.

The test mode is functional even if the gyrosphere is not yet
installed.
4. If not yet installed, the gyrosphere must now be installed:

See ”Power-up Function Test” on page 5-9 for details.
6. To bring the gyrocompass system into working order, the existing
alignment error must then be determined exactly and the error cor-
rection applied as described under ”Alignment Error Correction” on
page 7-9.
7. If required, determine the correction values for the magnetic com-
pass heading and enter the magnetic compass calibration table as
described under ”Magnetic Compass Calibration” on page 7-10.
