1STAND BY Indicator

ON : When in stand-by mode.

Blinking : When in cool-down mode.

CAUTIONS

•The cool-down mode continues for about 20 seconds, during which projection cannot–be started again. After the cooling- down period, the projector goes into stand-by mode, but the cooling fans will continue to run for about 10 minutes more before they stop (exept the cooling fan for the light-source lamp power supply which continues running as long as the MAIN POWER switch is on).

•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 block any of exhaust openings while in cool-down mode.

2OPERATE indicator

ON: When the projector is in operation (projecting)

3OPERATE button

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

Memo

While in the cool-down mode:

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

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 10 minutes (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 has suddenly gone off.

•When the fans have stopped.

•When the temperature inside has risen abnormally high.

CAUTION

• When an emergency mode is shown:

After the cooling fans (except the one for the light-source lamp power supply) have stopped, turn off the main power switch and unplug the power cord from the wall outlet.

Check that the filter covers are correctly installed. Then, plug in the power cord again and try operating 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.

4Lamp indicator

ON	: After the light-source lamp has been used for
	more than approx. 900 hours.

Blinking : Replace the lamp. (Ask the dealer where you purchased your projector to replace the lamp.)

5TEMP indicator

ON	: The temperature inside the projector has
	abnormally risen.

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).
