2. Change the faceplate, buttons, and volume control knob as needed.

a. (MLC 64 RS VC D only) If changing the faceplate on the MLC 64 volume control module, first remove the volume knob:

1. Rotate the knob until the dot on the knob is aligned with the bottom edge of the volume icon on the faceplate. The notches in the edge of the knob and the notch in the edge of the hole in the faceplate should be aligned, enabling you to access the hex screw that holds the knob in place.

2. Insert the small Allen wrench (provided) into the opening.

3. Rotate the Allen wrench one-half turn counterclockwise to loosen the hex screw, then lift off the knob.

b. Remove the faceplate from the MLC module as follows:

At the center top and bottom of the faceplate are tabs, which insert into the slots on the MLC circuit board. Insert the flat end of a small screwdriver into each of the holes at the top and bottom of the faceplate and press each tab inward until the faceplate is released (see the illustration at right).

c. If desired, replace the buttons in the faceplate as follows:

1. From the front of the faceplate, press the button membrane to be replaced backward through its slots in the faceplate until it comes free. If replacing the faceplate, repeat this step until all the buttons are removed.

	at opposite corners of the row. Press the pegs and buttons of the
