Shutting down the projector

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

power cord from the power outlet.
Direct power off
The AC power cord can be pulled out right after the projector is turned off. To protect the lamp, wait

• The brightness level of the projected image will change accordingly when you switch between different input
signals.
• For best display picture results, you should select and use an input signal which outputs at the projector’s native
resolution. Any other resolutions will be scaled by the projector depending upon the “aspect ratio” setting,
which may cause some image distortion or loss of picture clarity. See
Aspect Ratio on page 27 .
• 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 33 .
• Avoid turning on the projector immediately after turning it off as excessive heat may shorten lamp life.
• Lamp life results will vary depending on environmental conditions and usage.
