Appendix
About the Lamp
The projector lamp has a life of 2000 hours. Maintain proper ventilation to keep the lamp operating
throughout its lifetime. Do not subject the projector to unnecessary vibration to ensure that the
lamp does not break.
„ It is recommended that the lamp (sold separately) be replaced after approximately 2,000 cumulative hours
of use or when you notice a significant deterioration in the picture and color quality. The number of hours
the lamp has been used can be checked with “Lamp Timer” in the “Options” menu on the menu screen.
„ For lamp replacement, please consult your nearest Authorized Service Center or Dealer.
„ The actual lamp service life may be less than 2000 hours depending on the environment in which the
projector is used.
Caution Concerning the Lamp
„ This projector uses a pressurized mercury lamp. A loud sound may indicate lamp failure. Lamp failure is
caused by excessive shock, improper cooling, surface scratches or deterioration of the lamp due to usage.
The period of time up to failure largely varies depending on the individual lamp and/or the condition and
the frequency of use. It is important to note that failure can often result in the bulb cracking.
„ When the lamp replacement indicator and on-screen display icon are illuminated or are flashing, it is
recommended that the lamp be replaced with a new one immediately, even if the lamp appears to be
operating normally.
„ If the lamp breaks glass particles may spread inside the lamp cage or gas contained in the lamp may be
vented into the room from the exhaust vent. As the gas in this lamp contains mercury, ventilate the room
well if the lamp breaks and avoid all exposure to the released gas. In case of exposure to the gas, consult
with a doctor as soon as possible.
„ If the lamp breaks, there is also a possibility that glass particles may spread inside the projector.
If this happens, it is recommended you contact your nearest Authorized Dealer to remove the damaged
lamp and assure safe operation.
Replacing the Lamp
CAUTION! Do not remove the lamp unit immediately after operation of the projector. The
lamp will be hot and touching it can lead to burn or injury. Wait at least one hour after the
power cord is disconnected to allow the surface of the lamp unit to fully cool before removing
the lamp unit.
