1.Prepare the installation site. The MLC 60 D models can be installed in a standard US one-gang or two-gang electrical wall box or mounting bracket (“mud ring”).

CAUTION: Ensure that the electrical box is properly grounded.

b.Prepare and pull the cables through the electrical box or mounting bracket.

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.

 

2. On the back of the faceplate, set the new button membrane at

MUTE

the desired location, with the the two pegs in the upper-left and

LAPTOP

lower-right corners of the membrane (shown at left) in the holes

 

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

membrane into the faceplate.

d.Reattach the faceplate as follows (see the illustration at right):

Making sure that both the MLC and the board are upright, line up the tabs at the top and bottom of the faceplate with the slots on the board, and press the faceplate into the board until the tabs snap into place. The pegs in the upper-left and lower-right corners of the faceplate should be seated in the two diagonal holes on the MLC board.

e.(MLC 64 RS VC D only) If changing the volume control knob, press the new knob onto the spindle of the volume control module, making sure that the spindle is turned all the way to the left and that the dot on the knob is aligned with the bottom edge of the volume icon on the faceplate. Tighten the hex screw by rotating it one-half turn clockwise.

3.Connect the cables to the rear panel ports.

Attach the cables and IR emitters to the rear panel of the MLC and to the display device or switcher as required.

zzPort A RS-232 (RS models only): Connect a display device or switcher to

this serial port to be controlled via RS-232.
