WARNING
A mercury lamp used in this LCD projector is made of glass and has high internal pressure. The mercury
lamp can burst with a big noise due to deterioration resulting from a shock, crack and passage of time,
and can end its service life in unlit condition. Lamps also have a considerably different service life and
can sometimes end up in burst or turn to unlit condition soon after use. Furthermore, when the lamp is
blown up, glass fragments can get scattered around the lamp house and some gas containing mercury
inside the lamp can leak out of the projector’s air vent.
Handle the lamp with utmost care as it can burst during use if subjected to a shock or impact or if scratched or cracked.
Probability for the burst will increase if the lamp is used for extended period of time or used exceeding the
period of replacement. Avoid any reuse of an old lamp (used lamp) since such reuse can result in burst.
In case the lamp gets blown up in a short period of time after use, some electrical failures or troubles
other than the lamp itself may be suspected as causes.
Should the lamp burst (accompanied by a big bursting noise), perform ventilation sufficiently, and exercise
maximum caution not to inhale any gas out of the projector’s air vent or not to let it enter your eyes or mouth.
Should the lamp burst (accompanied by a big bursting noise), make absolutely sure to unplug the power
cord from the outlet and ask the store where you bought the lamp for immediate replacement.
When you dispose of any used lamps, be sure to observe and follow local ordinances and regulations of
the area or district where they are subjected to disposal. Generally speaking, the lamps are treated simi-
larly as glasses and bottles in most cases, but there are areas or districts where lamps are classified as a
separate collection, and so be sure to use caution.
Never use the lamp in a state where the lamp cover is removed.

Lamp Life
Projector lamps have a finite life. The image will become darker, and hues will become weaker, after a lamp has
been used for a long period of time.
Replace the lamp if the LAMP indicator is red, or the CHANGE THE LAMP message appears when the projector
is switched ON.
NOTE: The LAMP indicator is also red when the lamp unit reaches high temperature. Before replacing the lamp,
switch power OFF, wait approximately 20 minutes, and switch power ON again.
If the LAMP indicator is still red, replace the lamp.
