Operation 39
Operation under "High Altitude Mode" may cause a higher decibel operating noise level
because of increased fan speed necessary to improve overall system cooling and
performance.
If you use this projector under other extreme conditions excluding the above, it may display
auto shut-down symptoms, which is designed to protect your projector from over-heating.
In cases like this, you should switch to High Altitude mode to solve these symptoms.
However, this is not to state that this projector can operate under any and all harsh or
extreme conditions.

Shutting down the projector
1. Press Power and a confirmation message
displays 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.
3. Once the cooling process finishes, the POWER
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 44 for details.
• Do not unplug the power cord before the projector shutdown sequence is complete or
during the 90-second cooling down process.
• 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.
