• Do not send the projector in the soft case by parcel delivery service or cargo shipment. The
projector inside the soft case could be damaged.
• Select [HIGH] in Fan mode if you continue to use the projector for consecutive days. (From the
menu, select [SETUP] [OPTIONS(1)] [FAN MODE] [HIGH].)
• Do not try to touch the ventilation outlet on the left front (when seen from the front) as it can
become heated while the projector is turned on and immediately after the projector is turned
off.
• Do not turn off the AC power for 60 seconds after the lamp is turned on and while the Power
indicator is blinking blue. Doing so could cause premature lamp failure.

Lamp Replacement
• Use the specified lamp for safety and performance.
• To replace the lamp, follow all instructions provided on User’s Manual (
Replacing the Lamp

• Be sure to replace the lamp and filter when the message [THE LAMP HAS REACHED THE END OF
ITS USABLE LIFE. PLEASE REPLACE THE LAMP AND FILTER.] appears. If you continue to use the

If this happens, contact your dealer for lamp replacement.
A Lamp Characteristic
The projector has a high-pressure mercury lamp as a light source.
A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly
turning the lamp on and off will increase the possibility of its lower brightness.
