Connecting a sound system
For best home theater sound, connect the audio output of your video source 
directly to a stereo or surround sound system (connection 
1 in the following 
illustration). Refer to the instructions provided with your video device.
However, in some situations, you might want to use a simpler setup that uses the 
single speaker built into the projector (connection 
2 in the following 
illustration).

Connecting several video sources
If you have several video sources, connect them to an audio/video receiver or 
switch box, then connect the video output from the receiver or switch box to the 
projector using the highest quality connection available. Also connect the audio 
outputs from all sources to the receiver, switch box, or sound system.

Turning the projector off
1. Press the power button on the projector or remote control to turn off the 
projector. Do not hold the button down.
The power button blinks during the cool-down period, then the projector 
turns off. Even though the projector is off, it uses a small amount of power 
internally.
2. If you want, disconnect video and audio equipment from the projector during 
the cool-down period or after the power button stops blinking.
Ä
CAUTION: Do not disconnect power until the projector has cooled down (the fan stops) and the power button stops blinking. Otherwise, you might shorten the life of the lamp.
3. If you must unplug or remove the projector, wait until the power light stops 
blinking, then unplug the power cord.
If you try to turn on the projector again during the cool-down period, it will not 
turn on. Wait until the cool-down period ends and the power button stops 
blinking.
Moving the projector
When moving the projector:
■Allow the projector to cool down before moving it. Then disconnect all 
cables.
■Avoid bumps and jolts. Use a padded container when possible.
■Observe temperature and humidity limits (see “Specifications” on page 71). 
If the projector is cold, allow it to warm gradually to avoid condensation.
