Power-on

1.Turn on the device connected to the projector first.

2.Plug the power cord in the wall outlet.

•The POWER indicator lights up.

•If the power cord is unplugged from the wall outlet before the projector is cooled down completely after use, the fans may start rotating when the power cord is plugged in next time and the POWER button may not function. In this case, wait for the fans to stop and press the POWER button to light the indicator.

3.Press the POWER button on the control panel or the ON button on the remote control.

•It may take about one minute for the lamp to light up.

•The lamp occasionally fails to light up. Wait a few minutes and try to light the lamp again.

•After the POWER button is pressed, the image may flicker before the lamp becomes stable. This is not a product mal- function.

•Regardless of the setting of LAMP MODE in the INSTALLA- TION menu, the STANDARD lamp mode is activated by default whenever the projector is turned on. The LAMP MODE is set to either STANDARD or LOW depending on the setting last selected, and you cannot switch the LAMP MODE in about one minute after the lamp is on.

Important:

•If the lamp exceptionally turned off due to the power interruption or voltage drop, it can happen that the lamp does not turn on even if you switch again the power supply on. In that case, please pull the electric cord out of the consent and put it again in the consent about 10 minutes later.

•Do not cover the lens with the lens cap while the lamp is on.

•The projector starts warming up when the POWER button is pressed. During the warm-up process, images may appear dark and no commands are accepted.

•By blinking red, the STATUS indicator indicates that the lamp should be replaced soon. Replace the lamp when the STATUS indicator blinks red. (See page 35 and 38.)

•Images may not be projected with good quality in an extremely hot or cold environment. (This is not a product malfunction.)

•In order to ensure the safety in case of trouble with the projector, use an electrical outlet having an earth leakage breaker to supply the power to the projector. If you do not have such outlet, ask your dealer to install it.

4.Adjust the focus by turning the focus ring.

5.Choose your desired external input source using the SOURCE or COMPUTER or VIDEO or HDMI button.

•Each press of SOURCE button of the Control Panel enables the input source to switch in the following order: COMPUTER 1, COMPUTER 2, HDMI, VIDEO, and S-VIDEO.

•When pressing COMPUTER (1 or 2), HDMI, VIDEO, or S- VIDEO button on the remote control, the input source switches directly as the button pressed.

•The projector automatically selects the appropriate signal format. The selected signal format is displayed on the screen.

•The SOURCE, COMPUTER, VIDEO and HDMI buttons don’t function while the menu is being displayed.

•When COMPUTER is chosen as the source, images sup- plied from the computer may flicker. Press the W or X button

on the remote control to reduce flicker, if it occurs.

•To avoid permanently imprinting a fixed image onto your pro- jector, please do not display the same stationary images for long period.

6.Adjust the image size by turning the zoom ring.

•If necessary, adjust the focus and zoom again.

When fine streaks are seen on projected images

This is due to interference with the screen surface and is not a mal- function. Replace the screen or displace the focus a little.
