CAUTION The flanged edges of the top of the surface enclosure
are bevelled to an ultra-fine thickness of less than
0.04 (4/100)" (approximately 1 mm). These edges
are soft and can be easily nicked or bent. Exercise
caution when handling and mounting the enclosure.
Mishandling can damage the appearance of the
enclosure.
The surfaces of the HSA enclosure have screws and
other protrusions that could damage fine furniture.
Do not rest the enclosure on unprotected furniture.
6 . Remove the front panel from the enclosure.
7 . Disconnect any cables from the rear of the existing AAPs.
Carefully pull the cables out through the bottom of the
surface mount enclosure.
