Removing and replacing the MLC 64 VCM module knob and faceplate

Replacing the MLC 64 volume control knob

NOTE: It is not necessary to remove the faceplate or the board from the wallplate in order to replace the knob.

1.Rotate the knob to its lowest setting (the dot on the knob should be aligned with the bottom edge of the volume icon on the faceplate) to line up the notch in the edge of the knob with the notch in the edge of the hole in the faceplate, enabling you to access the hex screw on the knob.

2.Insert the small Allen wrench (provided) into the opening created by the two notches, until it stops.

3.Give the Allen wrench a one-half turn counterclockwise to loosen the hex screw holding the knob.
