small hole in the drywall near the center of the chosen location to verify that it is suitable
for mounting.

cutout in the drywall for the mounting hardware. Refer to the illustration in Prepare for
Installation on page 76 for cutout dimensions.
NOTE:Ensure that the cutout is as level and smooth as possible before proceeding.
The mounting plate allows only for minor adjustments once installed.
