Configuring a single button for input source selection

If you want to use only one button to select your input sources, you must program the button with one command for each source (up to four). Only one button has to learn IR commands; and it has enough memory blocks to learn four input selection commands. To use this programmed button to select an input, you must press it repeatedly to cycle through all the inputs until you reach the desired one.

To program a single button to select multiple inputs,

1.	Disconnect power from the MLC 52.
2.	To make the one programmed button easily recognizeable, r eplace all but one
	of the input (Video, PC, DVD, and/or VCR) button labels with the provided
	Not Used label, or remove the input label(s) and leave the button(s) blank.
3.	Apply power to the MLC.
4.	Set configuration switch #1 to On (up). The front panel buttons light dimly.
5.	Press the MLC button that will store the input selection IR codes. The button
	blinks for 5 seconds, during which time it is able to learn codes. On the rear
	panel, the first (bottom) IR learning LED starts flashing.) (If a command is not
	entered within 5 seconds, the button and LED stop blinking, and you must
	press the button again to put it in back in learn mode.)
6.	Within 5 seconds, press the display device remote control button from which
	the MLC button will learn the first input selection command. If the command
	has been learned successfully, the Learning LEDs on the rear panel blink in
	rapid progression from the top LED to the bottom, then back to the top.
7.	To program a second input selection command on the same button, press the
	button again. The button and the second rear panel IR learning LED begin to
	blink. On your display device’s remote control, press the next button whose
	function you want the MLC button to learn.
8.	Repeat the procedure described in steps 5 and 6 for additional commands you
	want to add to the button you are programming. Each MLC button can be
	programmed with up to four commands.
9.	When finished programming the input selection button, set rear panel DIP
	switch #1 to Off (down). Verify that the button has been programmed
	correctly by pressing it repeatedly to cycle through the inputs.
