Operating Precautions
Operating Precautions
z Never touch the glass of the lamp with your fingers. Doing so can damage the lamp and
shorten its life.
z The light source lamp is a consumable item. The average life of a lamp is approximately
2000 hours. After 2000 hours, a message appears to alert you to the need of lamp
replacement. However, note that the characteristics of a particular lamp or lamp operating
conditions can cause the lamp to start to go dim or even fail before the message appears.
z Lamps are guaranteed for 90 days from the date of purchase or for 500 hours operation,
whichever comes first.
z A mercury lamp with high internal pressure is used as the light source. A lamp that is
weakened by impact, damage, or expiration of its lamp life may explode or fail to light if
exposed to loud noise. Note that the performance of the lamp differs greatly from lamp to
lamp, and due to conditions under which a lamp is used.
z The replacement message appears and the LAMP indicator flashes red after the lamp life is
reached. When this happens, replace the lamp using the instructions provided in this User’s
Guide.
z If the lamp continues to be used after its lamp life is reached, after 100 hours the projector
will enter a cool down state and then go into standby. The projector will not turn on again
until you replace the lamp.
z When the lamp life is reached, the message “It is time to replace the lamp. Use the
procedure in the User’s Guide to replace the lamp as soon as possible.” appears on the
display for about 10 seconds, and the LAMP indicator starts to flash red in one-second
intervals. Replace the lamp as soon as possible after the message appears or the LAMP
indicator flashes.
z Replace the lamp with a special YL-41 replacement lamp, which should be available from
your original dealer. Use only the lamp type that is specified for this projector.
z Turn off the projector. After the POWER/STANDBY indicator changes to steady (not flashing)
amber, unplug the projector from the power outlet. Next, wait for at least 60 minutes before
removing the lamp. Note that the lamp cartridge becomes very hot during normal use and
during standby. Handling it when hot creates the risk of burn injury.
z The lamp contains mercury. Dispose of old lamps in accordance with the rules and
regulations of your local jurisdiction.
z When replacing the lamp, use the special screwdriver that comes with the YL-41 replacement
lamp.
Lamp Handling Precautions
Caution
Continued use of a lamp that has passed its lamp life increases the risk of
the lamp rupturing. Replace the lamp with a new one as soon as possible
after the replacement message appears.
