Then unplug the power cord, and wait at least 1 hour to allow the lamp to cool down enough to the touch. Interval of lamp replacement The recommended interval of lamp replacement is about 4000 hours*1*2 of consecutive use. Such interval differs depending on the operating environment and may be shorter than 4000 hours *1*2. Decrease in luminescence and/or color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 3000 hours *1, the indicator will blink alternately between green and red (while the be lit red only) and the lamp replacement message will appear on the screen for 1 minute everytime the lamp is turned on. When the lamp has been used for about 3800 hours *1, the replacement message (LAMP REPLACEMENT) will appear on the screen for 1 minute every 20 hours *1 thereafter. When the lamp operation time exceeds 4000 hours*1*2, the projector automatically shuts off. *1: Duration when LAMP MODE of the INSTALLATION menu is set to LOW.
