CAUTION
• Do not use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt-foot or
hanging on the wall can cause damage to the projector.
• 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.
• When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle
to the projector cabinet are tight.
Insufficient tightening of the two screws could result in the projector falling and causing injury.
• Select [High] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select
[Setup]

[Options]
→
[Fan Mode]
→
[High].)
• Do not turn off the AC power by pressing the main power switch or by unplugging the power cable when the
projector is powered on.
• Do not turn off the AC power for 60 seconds after the lamp is turned on and while the POWER indicator is blinking
green. Doing so could cause premature lamp failure.
Remote Control Precautions
• Handle the remote control carefully.
• If the remote control gets wet, wipe it dry immediately.
• Avoid excessive heat and humidity.
• Do not heat, take apart, or throw batteries into fire.
• If you will not be using the remote control for a long time, remove the batteries.
• Ensure that you have the batteries’ polarity (+/-) aligned correctly.
• Do not use new and old batteries together, or use different types of batteries together.
• Dispose of used batteries according to your local regulations.
Lamp Replacement
• To replace the lamp, follow all instructions provided on page 52 .
• Be sure to replace the lamp when the message [The lamp has reached the end of its usable life. Please
replace the lamp.] appears. If you continue to use the lamp after the lamp has reached the end of its usable
life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as
the pieces of glass may cause injury.
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.
CAUTION:
When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projector. Glass
fragments could fall if the lamp has been burned out.
