Mounting screws (4) — Use these to attach the MLC to a wall, furniture, or
other mounting surface.
b
Faceplate attachment screws (4) — Do not remove these screws during or
after mounting. They attach the faceplate to the MLC unit. Removing these
screws during or after mounting will cause the MLC to detach, and it may
then fall down into the wall or furniture.
