PLACEMENT CONSIDERATIONS

WIRING CONSIDERATIONS

1. Cut a foot-long piece of coat hanger.
Bend the wire (creating a right angle) leav-
ing 4-3/4” at one end for the CM-650BG
(this allows for the extra width of the
mounting dogs). Poke the “L-shaped” wire
into the pilot hole and turn it in a com-
plete circle and move it into the ceiling
cavity to make sure you have approxi-
mately 3-3/8” of depth. If the coat hanger
movement is obstructed by anything, fill
the hole(s) with spackle and try another
location. (See Figure 1).
