This projector is equipped with a lamp to project images. This lamp is a consumable, so it may burn out or its brightness may decrease during 
use. If this happens, replace the lamp with a new one as soon as possible. Be sure to replace the lamp with a new, commercially available lamp 
that is exclusive to this projector. Contact your dealer for purchase of the lamp.
Warning
 This product contains a high intensity lamp that contains a small amount of mercury. Disposal of this material may be 
regulated due to environmental considerations. For disposal information in the United States, refer to the Electronic 
Industries Alliance web site: www.eiae.org
 Be careful not to drop the lamp screws into the projector. Do not put a metal piece or flammable object into the projector. 
Using the projector with any foreign object present inside may result in electric shock or fire. If you can’t remove the foreign 
object from the inside, contact your dealer for removal. 
 Be sure to install the lamp securely. If the lamp is not installed properly, it will not illuminate. Improper installation may also 
result in fire.
 Do not shake the removed lamp or lift it above your face. You may injure your eye by flying or falling glass fragments.
 Do not replace the lamp immediately after use because the lamp cover is very hot. You may get burned. Turn off the power 
using the STANDBY/ON button. After the lamp goes out, wait about two minutes until the intake and exhaust fans for cooling 
the lamp stop rotating. Then unplug the power cable, and wait at least one hour to allow the lamp to cool down enough to 
the touch.
◆Interval of lamp replacement
The recommended interval of lamp replacement is about 3000 hours* of consecutive use when the LAMP MODE in the SETUP menu is set to 
CINEMA
. Such interval differs depending on the operating environment and may be shorter than 3000 hours*. Decrease in luminescence and/
or color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 2250 hours, the indicator will blink 
alternately between green and red (while the lamp is lit; when the lamp is not lit, the indicator will be lit red only) and the lamp replacement 
message will appear on the screen for one minute everytime the lamp is turned on. When the lamp has been used for about 2850 hours, the 
replacement message (LAMP EXCHANGE) will appear on the screen for one minute every 15 hours thereafter.
When the lamp operation time exceeds 3000 hours*, the projector automatically shuts off and can not be 
used until the lamp is replaced and the lamp operation time is reset.
*When the LAMP MODE is set to STANDARD, this duration will be decreased to 2000 hours.
Caution
 Be sure to use the replacement lamp cartridge PJL-725. Other lamp cartridges are not suitable for use in this projector.
 Do not remove the lamp for any purpose other than replacement. Unnecessary removal of the lamp may result in a 
breakdown.
 This projector uses a high-pressure mercury lamp as the light source. The high-pressure mercury lamp may explode or fail 
to illuminate permanently because of an impact, scratch, or deterioration through use. The period of time until explosion or 
permanent failure to illuminate varies considerably from lamp to lamp, depending on operation conditions. Therefore, the 
lamp may explode soon after the start of use.
 The possibility of explosion of the lamp increases if you use it beyond its replacement period. When the lamp replacement 
warning appears, replace it with a new one immediately, even if the lamp is still lighting normally.
 When the high-pressure mercury lamp explodes, glass fragments will scatter inside or outside the lamp box and the gas 
charged inside the lamp will diffuse inside or outside the projector. The gas inside the lamp contains mercury. Be careful not 
to breathe it and avoid it from entering your eye or mouth. If you should breathe it or if it should enter your eye or mouth, see 
a doctor immediately.
 In the event that the high-pressure mercury lamp has exploded, glass fragments may have been scattered inside the 
projector. Ask your dealer to replace the lamp and to inspect the inside of the projector. When you clean or replace the lamp 
by yourself, be sure to hold the handle of the lamp. You may get injured by glass fragments.
 Do not replace the lamp with the projector installed on the ceiling. Glass fragments may fall from the projector, entering your 
eye or mouth and causing injury.
 When placing the projector upside down to replace the lamp or conduct maintenance, be sure that the projector is securely 
placed before working with it.
