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 until the light-source lamp is sufficiently cooled down after the OPERATE button was pressed. During the cooling-down, never turn off the main power switch. Turn it off only after the cooling fans (except the one for the light-source lamp power supply) have stopped running.

(The cooling fans will run for about 10 minutes after the STAND BY indicator has changed from flashing (for about 20 seconds) to steady lighting.)

•If you press the OPERATE button immediately after the light-source lamp lights, it takes about 30 seconds for the lamp to go off. To turn the lamp on again, wait 20 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 the cooling fans will continue to run for about 10 minutes more before they stop (except the cooling fan for the light-source lamp power supply which continues running as long as the MAIN POWER switch is on).

–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.
