1STAND BY Indicator

ON : When in stand-by mode.

Blinking : When in cool-down mode.

Memo

About the cool-down mode:

This projector has a function to cool down the heated lamp for a fixed period of time (approx. 120 seconds) after projection is finished. This feature is referred to as the cool-down mode.

CAUTION

•The purpose of the cool-down mode is to prevent inner parts from being deformed or broken by heat from the heated lamp as well as to prolong the life of the lamp. Do not turn off the main power switch while in the cool-down mode. Also, do not place the projector on its side or stand it upright; this may block the exhaust vents.

Note

•While the TEMP indicator is on (during abnormal temperature), the power is automatically cut off, and an emergency mode is shown (with the EMERGENCY indicator blinking).

6EMERGENCY indicator

Blinking: Something abnormal has occurred with the projector.

Memo

About the emergency mode:

The emergency mode is shown when the following anomalies have occurred with the projector (the EMERGENCY indicator blinks). In the emergency mode, projection is automatically interrupted and the cooling fans operate for about 20 seconds.

•When the air filter is displaced.

•When the filter is clogged.

•When the light-source lamp has suddenly gone off.

•When the fans have stopped.

•When the temperature inside has risen abnormally high.

•When the AC power supply is suddenly cut or interrupted.

CAUTION

• When an emergency mode is shown:

After the cooling fans have stopped, turn off the main power switch and unplug the power cord from the wall outlet. Make sure the lamp-replacement cover and the air filter are correctly installed. Then, plug in the power cord again and operate the projector.

If it goes into an emergency mode again, after the cooling fans have stopped, turn off the main power switch, unplug the power cord, and call your dealer for repair.

ENGLISH

When the projector is in the stand-by mode, press this button one second or more, and the main power switch is turned on, causing the OPERATE indicator to light. Press it one second or more again, and the projector goes into the cool-down mode, then stand-by mode.

If you press the OPERATE button, the projector is not turned on.
