After turning off the power, follow the procedures given below. POWER indicator LAMP REPLACEMENT indicator TEMPERATURE WARNING indicator ProblemMaintenance IndicatorCondition Possible Solution TEMPERATURE WARNING indicatorThe internal temperature is abnormally high.• Blocked air intake.• Relocate the projector to an area with proper ventilation. • Clean the filter.

A significant deterioration of the picture and color quality occurs. The power will automatically turn off and the projector will enter standby mode. “LAMP” will appear in red in the lower-left corner of the picture, and the power will turn off. Lamp The lamp in this projector operates for approximately 1,000 cumulative hours, depending on the usage environ- ment. It is recommended that the lamp be replaced after 900 cumulative hours of use or when you notice a significant deterioration of the picture and color quality. The lamp usage timer can be checked with the On-screen Display. (See page 34.) CAUTION • Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating. • As the usage environment can vary significantly, the projector lamp may not operate for 1,000 hours. • “1,000 hours” above indicates average life span and should be used for reference only. This is different than the warranty period. • For safety, the power will not be turned on from the fourth times when turning on the power without changing the lamp after use for 1,000 hours. • If the TEMPERATURE WARNING indicator illuminates, follow the solution listed above and then wait until the projector has cooled down completely before turning the power back on. (At least 5 minutes.) • If the power is turned off and then turned on again, as during a brief rest, the LAMP REPLACEMENT indicator may be triggered, preventing the power from going on. Should this occur, remove the power cord from the wall outlet and plug it in again.
