Basic operation (continued)

Power-off

Use the following procedure to turn off the projector. Do not turn off the projector by unplugging the power cord while the lamp is on. Unplugging while the lamp is on degrades the lamp’s performance and causes failure in the projector.

1. Press the POWER button.

•The message “POWER OFF? YES : PRESS AGAIN” appears on the screen.

•To cancel, press any button except the POWER button. (Some buttons on the remote control don’t function for cancel.)

2. Press the POWER button within 10 seconds again.

•The lamp will go out and the STATUS indicator will start blinking.

•Though the lamp goes out at this second press of the POWER button, the air outlet fans continue operating for one minute to cool down the lamp and LCD panels. The STATUS indicator will stop blinking.

3. Unplug the power cord.

•The POWER indicator will go out.

•If the power cord should be unplugged accidentally while either the air inlet fan or the air outlet fans are operating or the lamp is on, allow the projector to cool down for 10 minutes with the power off. To light the lamp again, press the POWER button. If the lamp doesn’t light up immediately, repeat pressing the POWER button two or three times. If it should still fail to light up, replace the lamp.

Important:

•When storing the projector in the provided carrying case, the lens should face up.

AUTO POSITION button

When the image isn’t projected in the right position with COMPUTER selected as the input source, follow the procedure below.

1.Project a bright image such as the “Recycle Bin” window on the full screen.

2.If the screen saver is running, turn it off.

3.Press the AUTO POSITION button.

•If the image is still not in the right position, adjust the image position using the SIGNAL menu.

Volume from the speaker

Press the VOLUME + or – button to change the volume from the speaker.

The volume control bar will appear on the screen.

VOLUME 15

•The volume control bar will disappear about 10 seconds after the VOLUME button is released.

•The VOLUME buttons don’t function while the menu selection bar or the menu is being displayed.

•When a high-level audio signal, such as a DVD audio signal, is supplied to the AUDIO IN terminal, the output from the speaker may be distorted.

AV mute

The video and audio signals are temporarily muted when the MUTE button is pressed. To cancel muting, press the MUTE button again.

•If MUTE MODE in the INSTALLATION menu is set to IMAGE, the splash screen will appear when the MUTE button is pressed.

•You can alter the splash screen optionally. See page 21.

•When muting starts, the lamp mode becomes LOW, darkening the display of IMAGE. This is not a product malfunction.

Caution:

•After using the projector, wait one minute for the air outlet fans to stop. Then unplug the power cord from the wall outlet.

•The lamp can’t be lit again for one minute after turned off for safety purpose. It will take another one minute for the STATUS indicator to go out. If you want to turn on the projector again, wait until the indicator goes out, and then press the POWER button.

•The air outlet fans rotate faster as the temperature around the projector rises.

•When the temperature around the projector rises high, the sign “TEMPERATURE!!” blinks red on the screen. If the temperature stays high, the lamp will go out automatically.
