24 Using the projector and remote control
Turning the power off
1. Press Power and an on-screen prompt displays.
Press Power a second time to turn the projector
off.
2. The Power indicator light flashes and the lamp
shuts down, however, the fan continues to run for
approximately 110 seconds to cool down the
projector.
To protect the lamp, the projector will not respond to any
commands during the cooling process.
3. Only after you notice that the fan has stopped,
should you disconnect the power cord from the
wall socket and the projector.
Do not unplug the power cord before the projector
shutdown sequence is complete or during the 110-second
cooling down process.
If the projector was not properly shut down, and you attempt to restart it soon thereafter, the fan may run for a few
minutes to cool it down properly before you can restart. You will have to wait before you can press Power again to
start the projector after the fans stop.
