Shutting down the projector

1.Press Power and a confirmation message will

display prompting you.

If you don't respond in a few seconds, the message will disappear.

2. Press Power a second time. The POWER indicator light flashes orange, the projection lamp shuts down, and the fans will continue to run for approximately 90 seconds to cool down the projector.

To protect the lamp, the projector will not respond to any commands during the cooling process.

To shorten the cooling time, you can also activate the Quick cooling function. See "Quick Cooling" on page 50 for details.

3.Once the cooling process finishes, a "Power Off Ring

Tone" will be heard. The POWER indicator light is a steady orange and fans stop. Disconnect the power cord from the power outlet.

• To turn off the power ring tone, see "Turning off the Power on/off ring tone" on page 39 for details.

•If the projector is not properly shut down, to protect the lamp, when you attempt to re-start the projector, the fans

will run for a few minutes to cool down. Press Power again to start the projector after the fans stop and the POWER indicator light turns orange.
