Memo

When the OPERATE button is pressed but the power is not supplied:

•If the filter or lamp replacement opening cover is displaced, the power is not supplied. Check them for correct installation.

•You must press the OPERATE button for one second or more.

CAUTIONS and NOTES

Do not turn off the MAIN POWER switch suddenly while the projector is being used or immediately after it has been used. This could cause a malfunction.

•Since the projector uses a high-intensity lamp and is heated to high temperature, cooling fans are operating even during projection. So, after use, the cooling fans continue to run from when the OPERATE button is pressed until the light-source lamp is cooled down. During cooling, the STAND BY indicator blinks to alert the cooling fans are running. During this time, do not turn off the main power switch. After the cooling of the light-source lamp is finished (the fans stop) and the STAND BY indicator comes on, then turn off the main power switch.

•If you press the OPERATE button immediately after the light-source lamp lights, it takes about 40 seconds for the lamp to go off. To turn the lamp on again, wait 10 seconds or more before pressing the OPERATE button.

When the TEMP indicator lights, the power turns off automatically.

•While the light-source lamp is on, if an abnormal temperature rise is detected, the TEMP indicator comes on, the power is automatically cut off, and the projector’s EMERGENCY indicator blinks (goes into an emergency mode).

When the EMERGENCY indicator blinks, turn off the main power switch after the fans have stopped running.

•If the following abnormality occur to the projector, it goes into an emergency mode (the EMERGENCY indicator blinks). When the projector goes into an emergency mode, it stops projecting automatically and runs the fans for about 20 seconds.

–When the filter is dislodged.

–When the filter is clogged.

–When the light-source lamp suddenly goes off.

–When the fans stop running.

–When the temperature inside rises abnormally high.

•When the projector goes into an emergency mode:

After the fans have stopped, turn off the MAIN POWER switch and pull out the power cord. After that, re-insert the power cord and try to operate the projector. If it goes into emergency again, after the fans have stopped, turn off the main power switch, pull out the power cord, and consult your authorized dealer or service center for repair.
