NOTE
New Terrain/Obstacle cards, Jeppesen Aviation Database and other
optional features (i.e. TAWS unlock 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 configuration mod-
ule. The old Terrain and other cards will no longer work as they will remain
locked to the old System ID number.
Table 4-1 lists maintenance related system messages, possible causes, and recom-
mended actions.
