displays prompting you.

2. Press II 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.

indicator light is a steady orange and fans stop.

4. Disconnect the power cord from the wall socket if the projector will not be used in an extended period of time.

• 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 43 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.
