Replacing the lamp
This projector is equipped with a lamp to project 
images. This lamp is a consumable. It may burn out 
or its brightness may decrease during use. In such 
cases, replace the lamp with a new one as soon as 
possible. Be sure to replace the lamp with a new lamp 
separately sold that is exclusive to this projector. 
Contact your dealer for purchase of the lamp. 
Spare lamp  VLT-XL7100LP
Warning:
•  Be careful not to drop the lamp fixing screws into
the inside of the projector. Don’t 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. When you can’t 
remove the foreign object from the inside, contact 
your dealer for removal. 
•  Do not touch the lamp with bare hands or give
a shock to the lamp. Attach the lamp properly. 
Improper handling may cause explosion.
•  Be sure to install the lamp securely. When the lamp
isn’t installed properly, it won’t illuminate. Improper 
installation may also result in fire.
•  Don’t shake the removed lamp or don’t lift it above
your face. You may be injured in your eye by flying 
or falling glass fragments.
•  Don’t replace the lamp immediately after use
because the lamp cover is very hot. You may get 
burned. Turn off the power using the POWER 
button. After the lamp goes out, wait about 2 and 
a half minutes until the intake and exhaust fans for 
cooling the lamp stop rotating. Then unplug the 
power cord, and wait at least 1 hour to allow the 
lamp to cool down enough to the touch.
Interval of lamp replacement
The recommended interval of lamp replacement is 
about 4000 hours
*1*2
 of consecutive use. Such interval 
differs depending on the operating environment 
and may be shorter than 4000 hours
*1*2
. Decrease 
in luminescence and/or color brightness indicates 
that the lamp needs to be replaced. When the lamp 
operation time exceeds 3000 hours
*1
, 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 1 minute everytime the 
lamp is turned on. When the lamp has been used 
for about 3800 hours
*1
, the replacement message 
(LAMP REPLACEMENT) will appear on the screen for 
1 minute every 20 hours
*1
 thereafter. 
When the lamp 
operation time exceeds 4000 hours
*1*2
, the projector 
automatically shuts off.
*1: Duration when LAMP MODE of the INSTALLATION menu 
is set to LOW. When it is set to STANDARD, this duration 
will be shorted.
*2: When LAMP MODE is set to STANDARD, this duration 
will be shorted to 3000 hours.
Caution:
•  Don’t 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 
instruction of lamp replacement 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 or 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 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. 
•  When removing the lamp from the ceiling-mounted
projector, use the lamp replacement tray packed 
with the projector or option lamp to prevent glass 
fragments from scattering.
•  Be sure to use the lamp exclusive to this projector,
VLT-XL7100LP. Use of other lamps may cause a 
failure of the projector.
