Turning the power On and Off (continued)
If not using the projector for long periods of time, turn the MAIN POWER switch at the front of the projector
to the OFF position.
If you press the POWER switch accidentally while the projector is being used and then immediately turn the
power back on, the picture may not appear.
The REMOTE POWER function may cause the operation of the POWER button on the Remote Control Unit to
be disabled temporarily.
If you turn off the POWER button while leaving the MAIN POWER switch on, the projector still draws
approximately 8 Watts of power, even though the fan has stopped.
If the lamp does not turn on right away, the power indicator flashes between green and orange for 30 seconds.
Then the projector automatically attempts to turn on the lamp again.
The projector is equipped with a lens retracting function which activates automatically when the power is
turned off. However, the lens will not return to the previous position even if the power is turned back on again.
To disable this function, see the section on "Using the lens retracting function."
