• For the case of installation in a special state such as ceiling mount, the specified  
mounting accessories ( 18) and service may be required. Before installing the  
projector, consult your dealer about your installation.  
The screen position may shift after installation if the projector is suspended from the  
ceiling or other location due to the flexibility of the plastic projector body. If readjustment is  
necessary, consult with your dealer or service personnel.  
• The projected image position and/or focus may change during warm-up (approx. 30  
minutes after the lamp is turned on) or when the ambient conditions change. Readjust  
the image position and/or focus as necessary.  
Since the projector features a short throw, be aware that it is required to select a screen  
carefully to have better performance.  
- A soft screen such as a pull-down screen may cause serious distortion of a projected  
image. A hard screen such as a board screen is recommended for use with this projector.  
- A high-gain screen such as a bead screen that has narrow viewing angle is not suitable  
for this projector. A low-gain screen (around 1.0) such as a matte screen that has wide  
viewing angle is recommended for use with this projector.  
-
A screen with a weave pattern may cause moiré on the projected image, which is not a failure  
of the projector. A screen that has less moiré effects is recommended for use with this projector.

Replacing the lamp (continued)  
HIGH VOLTAGE  
HIGH TEMPERATURE  
HIGH PRESSURE  
WARNING The projector uses a high-pressure mercury glass lamp. The lamp  
can break with a loud bang, or burn out, if jolted or scratched, handled while hot, or  
worn over time. Note that each lamp has a different lifetime, and some may burst or  
burn out soon after you start using them. In addition, if the bulb bursts, it is possible  
for shards of glass to fly into the lamp housing, and for gas containing mercury and  
dust containing fine particles of glass to escape from the projector’s vent holes.  
About disposal of a lamp: This product contains a mercury lamp; do not put  
it in a trash. Dispose of it in accordance with environmental laws.  
• For lamp recycling, go to www.lamprecycle.org (in the US).  
• For product disposal, consult your local government agency  
For more information, ask your dealer.  
• If the lamp should break (it will make a loud bang when it does),  
unplug the power cord from the outlet, and make sure to request a  
replacement lamp from your local dealer. Note that shards of glass  
could damage the projector’s internals, or cause injury during handling,  
so please do not try to clean the projector or replace the lamp yourself.  
• If the lamp should break (it will make a loud bang when it does), ventilate the  
room well, and make sure not to inhale the gas or fine particles that come out  
from the projector's vent holes, and not to get them into your eyes or mouth.  
Disconnect  
the plug  
from the  
power  
• Before replacing the lamp, turn the projector off and unplug the power  
outlet  
cord, then wait at least 45 minutes for the lamp to cool sufficiently.  
Handling the lamp while hot can cause burns, as well as damaging the lamp.  
• Never unscrew except the appointed (marked by an arrow) screws.  
Do not open the lamp cover while the projector is suspended from a ceiling.  
This is dangerous, since if the lamp’s bulb has broken, the shards will fall out  
when the cover is opened. In addition, working in high places is dangerous, so  
ask your local dealer to have the lamp replaced even if the bulb is not broken.  
• Do not use the projector with the lamp cover removed. At the lamp  
replacing, make sure that the screws are screwed in firmly. Loose  
screws could result in damage or injury.  
• Use only the lamp of the specified type. Use of a lamp that does not  
meet the lamp specifications for this model could cause a fire, damage or  
shorten the life of this product.  
• If the lamp breaks soon after the first time it is used, it is possible  
that there are electrical problems elsewhere besides the lamp. If this  
happens, consult your local dealer or a service representative.  
Handle with care: jolting or scratching could cause the lamp bulb to burst during use.  
• Using the lamp for long periods of time, could cause it dark, not to light  
up or to burst. When the pictures appear dark, or when the color tone  
is poor, please replace the lamp as soon as possible. Do not use old  
(used) lamps; this is a cause of breakage.  
14  
Cleaning and replacing the air filter  
The air filter has two kinds of filters inside. Please check and clean the air filter periodically.  
When the indicators or a message prompts you to clean the air filter, comply with it as soon  
as possible. If the filters are damaged or heavily soiled, replace them with the new ones. To  
prepare the new filters, make contact with your dealer and tell the following type number.  
Type number : UX37191 (Filter set)  
When you replace the lamp, please replace the air filter. An air filter of specified type will  
come together with a replacement lamp for this projector.
