5. OPERATION

This section describes how to select a computer or video source, ad- just the picture and sound, edit a signal and adjust all other settings and adjustments for proper projector set-up.

General Controls

Before you turn on the projector ensure that the computer or video source is turned on and that the lens cap is removed.

1. Turn On The Projector

Plug the supplied power cable into the AC outlet. The main power switch is on the rear panel of the projector. By turning this switch on, the projector will go into its standby mode and the POWER indicator will glow orange. Only after you press the 'POWER ON' button on the remote control or projector cabinet will the POWER indicator turn to green and the projector will fully turn on.

2. Select The Computer Or Video Source

Press the INPUT button on the remote control to select the desired source. Or press the MENU button on the remote control and use the Source Select to select your video source: Video, S-Video, RGB, Y/Cr/Cb, RGB Digital (SX6000 only) or SDI.

3. Adjust The Image

Press the ADJUST PICTURE button or the ADJUST WHITE BAL on the remote control or select the [Menu] → [Adjust (Source)] to adjust the picture.

4. Turn Off The Projector

First press the POWER OFF button on the remote control or the projector cabinet. Allow the fan to cool the projector for three min- utes. This will extend the life of the lamp. After the cooling fan stops working, the POWER indicator will change to a steady orange glow and the projector will be in the stand-by mode. Then turn off the main power switch on the rear panel. The POWER indicator will go out. If you desire to move the projector then unplug the power cable.

IMPORTANT:

•The projector should be unplugged if it will not be used for an ex- tended period.

•If you want to turn off the image briefly (five minutes or less), press the MUTE PICTURE button instead of turning the projector off and on.

•The projector will display a black, blue image or logo if no input signal is present.

•Do not turn the projector off and then immediately back on. The Pro- jector needs to cool down for three minutes before it is powered on again.

CAUTION: Do not turn off the main power while the cooling fan is working.
