Replacing the lamp
This projector is equipped with 2 lamps 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.

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
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 1
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 2000 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-XD8600LP. Use of other lamps may cause a
failure of the projector.
