Removing and replacing the MLC 64 VCM module knob and
faceplate
The MLC 64 is provided with one black and one white VCM faceplate and volume control
knob. You can change the faceplate, knob, or both on the volume control module as
described in the following procedures.
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.
