Configuring the MLC 52 for a power-off confirmation

The MLC 52 can be configured so that the projector Power Off button does not need to be pressed twice for confirmation. Using the macro mode feature, you can send two power off commands sequentially from a single press of the MLC’s Off button.

To configure the MLC’s Off button to issue both a power off and a power off confirmation command,

1.	Ensure that power is applied to the MLC 52.		ON
2.	Set configuration DIP switch #1 on the rear panel to On (up).
		1		2	3	4
3.	Program the MLC’s Off button’s first two command memory
	blocks (commands #1 and #2) with a projector off command. See
	“Configuring using IR learning” in chapter 3, “Operation,” for procedures.

Programming the Off button for a projector that requires a confirmation

4.	Put the MLC’s Off button that you have just programmed into macro mode
	by pressing and holding the button for 3 seconds. The orange LED on the
	back panel, labeled “E,” flashes rapidly five times, then turns off, indicating
	that the button is now configured for macro mode.
5.	Set configuration DIP switch #1 on the MLC rear panel to Off (down).

Now, with one press of the MLC Off button, you can issue the two projector off commands needed to both answer the projector’s confirmation prompt and turn the projector off. The commands are issued in succession at 1.5-second intervals.
