ACU DATUM
0 = Normal
1 = Reversed. It may be necessary to select “Reversed” if the HDG or CRS Datum
drives the autopilot in the opposing direction. Some HSI units use
reversed logic for CRS and HDG Datum. Verify through ground
test the proper setting.

EXITING / SAVING DATA
To exit the Installation Menu press the MENU button. All data will be saved as it was
displayed on each page. The system will reboot and “INITIALIZING” will appear on the
display for approximately 40 seconds. Normal operation continues.

RSM Calibration
10.5.1
Calibration Overview
The Remote Sensor Module must be calibrated by performing a compass swing in the
aircraft for any new installations and any follow up maintenance activities that could
affect RSM accuracy.
Such activities might include but are not limited to the replacement of the RSM,
replacement of the Configuration Module, installation of a mechanical or electrical device
in the vicinity to the RSM, installation of an appliance that might generate a magnetic
interference.
An overview of the RSM Calibration procedure is as follows (see Figure 10-10):
CAUTION: When a Calibration is initiated, the aircraft must be turned as described below. If the
calibration is initiated and then accepted without moving the aircraft, an erroneous
calibration will be written to the Configuration Module, potentially resulting in failure to
initialize.
A heading will be checked to verify the reasonableness of EFD heading prior to
calibration.
The aircraft will be taxied to a magnetically quiet and level area at least 200ft from
metal buildings and clear of metal grates, manhole covers and rebar within the
concrete. A Compass Rose is ideal for this procedure.
The aircraft can start from any heading.
