Caution on Handling the Optional Lens
When shipping the projector with the optional lens, remove the optional lens before shipping the projector. The lens
and the lens shift mechanism may encounter damage caused by improper handling during transportation.
Do not hold the lens part when carrying the projector.
Doing so could cause the focus ring to rotate, resulting in accidental dropping of the projector.
Lamp Replacement
• To replace the lamp, follow all instructions provided on page
• 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.
Important Information
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.
CAUTION
• Always carry your projector by the carrying handle. Before doing so, be sure to lock the carrying handle in place.
To lock the carrying handle, see “To lock the carrying handle” on page
.
• Do not use the tilt-foot for purposes other than originally intended. Misuses such as using the tilt foot to carry
or hang (from the wall or ceiling) the projector can cause damage to the projector.
• Do not send the projector in a 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] → [FAN MODE] → [HIGH].)
• Before using Direct Power Off, be sure to allow at least 20 minutes immediately after turning on the projector
and starting to display an image.
• Do not unplug the power cable from the wall outlet or projector when the projector is powered on. Doing so can
cause damage to the AC IN connector of the projector and (or) the prong plug of the power cable.
To turn off the AC power supply when the projector is powered on, use a power strip equipped with a switch
and a breaker.
• 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 green. Doing so could cause premature lamp failure.
