4. Hold the remote control of the display device between 4 and 14 inches (10 to 36 cm)
away from the MLC and point it at the IR Transmit/Receive LEDs on the MLC. Within
5 seconds of pressing the MLC button (step 3), press the button on the remote
control whose function you want the selected MLC button to learn.
NOTE: For repeating command codes, such as those that increment and
decrement a function (for example, turning the volume up and down), hold the
button on the projector remote control for at least 3 seconds.
• If no IR command is detected within 5 seconds, the LEDs and the front panel
button time out and stop blinking.
• If the IR code was learned, the rear panel LEDs blink rapidly in succession from
the top down, then back up to the top.
• If the IR code was not learned, the rear panel LEDs blink in random order.
5. If you do not want to program additional commands on the button, repeat steps 3
and 4 for the next button that you want to program.
If you want to program another command to the same button, press the button again
(you can program up to four commands on one button). The next IR learning LED
on the rear panel begins flashing (for example, if you have already programmed two
commands on this button, the third LED from the bottom flashes).
6. When you are finished programming buttons on the MLC, set configuration switch 1
on the rear panel to Off (down).
7. Press the buttons that you configured to verify that the commands you entered have
been learned. If you have an IR Emitter connected on the IR output, it should blink
(see Wiring for IR Control on page 13).
Removing IR Commands from a Button
If you want to delete a command that has been programmed onto a button, you must
remove all the commands programmed to that button as follows:
1. While the MLC 52 is powered on, set configuration switch 1 to On (up).
2. Press the button for which you want to delete commands, then within 2 seconds
press the same button again. The IR learning LEDs turn off.
3. Verify that all commands were erased from the button by pressing the same button
again. If the commands have been erased, only LED 1 (the bottom LED) blinks; the
other LEDs remain off.
4. When finished removing commands, set switch 1 to Off (down).
