Restore
This command restores backup files from a USB memory stick. The files must
be create with a backup process first. The files are expected to be located in
Nesis-Backup
folder. If only one such folder exists on the USB memory stick,
then restore process is automatic. If several
Nesis-Backup
folders exists (each
in its own parent folder), then a windows is shown to select the parent folder
to copy from.
On success, all above mentioned files are restored and Nesis is restarted.
Important note: The Nesis software version is important. The restore will
fail if the backup was created with newer version. For example: Backup was
created with Nesis running SW version 3.4 and a restore attempt is made on
Nesis with SW version 3.3. This restore will fail without a warning and it will
leave the product in an undetermined state. The restore will be successful
only on versions 3.4 and above.

AHRS-Leveling
During the assembly of the AD-AHRS-GNSS unit (AIRU) into the primary
Nesis and during the installation of the Nesis display into the instrument
panel, a small misalignment may appear. This means that internal axes of the
AIRU are not parallel to the airplane axes – the unit is slightly rotated. Such
misalignment can be adjusted without loss of precision using the procedure
described in this section.
Please note that the attitude can’t be adjusted when the airplane is flying or
engine is running.
Please make sure that aircraft is level for both, roll and pitch. Make also sure
that Nesis is turned on for at least ten minutes – this warms up the internal
electronics and stabilizes numerical filters.
Before the automatic alignment is made, the yaw misalignment shall be de-
termined.
Follow next steps to open the AHRS Level window:
1. Select
Options
on the main menu.
2. Select the
Service
icon and enter product specific password to access the
service options.
3. Select the
AHRS Level
icon from service page.
A window similar to one shown on Figure 55 appears on the screen.
