Contact your dealer before replacing the lamp.
For the optional lamp, see the item “Optional Parts” of the Table 12.
Before replacing the lamp, switch power OFF, remove the power cord from the power outlet, and
wait approximately 45 minutes until the lamp has cooled. The lamp may explode if handled at high
temperatures.
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. See Table 9 of P.20 and Table 10 of P.21.
• 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.
NOTE
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. You are advised to follow instructions for lamp
replacement as soon as they are given (Refer to Table 9 of Page 20, Table 10 of Page 21).
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. Under such
circumstances, consult the store where you purchased it or a service company.
• 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. You should not engage in cleanup or replacement of the lamp by
yourself since scattered glass fragments can damage the inside of projector or can result in
personal injury when you handle it.
• 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 similarly 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.
