Chassis Cover Replacement
This procedure describes the removal and replacement of the sheet metal chassis cover on the unit.
Note:
Every unit leaving the factory or authorized service center has a warranty warning label applied
to the rear panel and chassis cover. Removing this label leaves a distinctive checkerboard residue on
the unit. Before removing the chassis cover, verify the integrity of the label. Removal of this label by
anyone other than an authorized service center voids the warranty.
