Buttons

Tip

	The MLC 104 IP Plus controller has backlit buttons. The button
	caps are removable so the button labels can be changed. For
	instructions on how to change the buttons, refer to chapter 1 of
	the MCL 104 IP Plus User's Manual.
A	Display On/Off buttons — After they have been configured
	(for instructions, see "Configuring the On and Off buttons" in
	chapter 3), press the On button to turn the display device on,
	and press the Off button to power it off. Only one of these two
	buttons can be selected (active) at once. You can assign other
	functions to these buttons via the Global Configurator software.
B	Input selection buttons — By default, these buttons are a
	mutually exclusive group (only one of these buttons can be
	selected at a time).
	Press an input selection button to select the desired audio and
	video input to the projector or an optional Extron switcher. The
	button lights brighter and remains lit while an audio-video
	input is selected.
