Configuration" Page in the
System Group.
3. Turn the Cursor on by pressing
the FMS Knob.

cabling.
•
Check the GDL 69A and MFD
interconnect.
•
See Section 7 for GDL configuration
instructions.
•
If problem persists, replace master
configuration module, check config
module harness for faults and
replace if necessary.
NOTE
New Terrain/Obstacle cards,
Jeppesen Aviation Database and
other optional features (i.e. TAWS
card) will need to be replaced if the
master configuration module is
changed. The System ID number
will change to a new number when
installing a new master config
module. The old Terrain and other
cards will no longer work as they will
remain locked to the old System ID
number.
