Feeling for obstructions behind the ceiling surface.

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).
