OPERATION

The IR Remote Keypad is the most commonly used keypad. It controls the
projector by way of wireless communications from a battery-powered infrared
(IR) transmitter. Use the keypad the same way you would use a remote keypad
supplied with a television or VCR. When making key presses, point the keypad
either toward the screen or toward the front or rear of the projector.
