Interval of lamp replacement

The recommended interval of lamp replacement is about 6000 hours*1*2 of consecutive use. Such interval differs depending on the operating environment and may be shorter than 6000 hours*1*2. Decrease in luminescence and/or color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 4500 hours*1, the indicator will blink alternately between green and red (while the lamp is lit; when the lamp is not lit, the indicator will be lit red only) and the lamp replacement message will appear on the screen for one minute everytime the lamp is turned on. When the lamp has been used for about 5700 hours*1, the replacement message (LAMP EXCHANGE) will appear on the screen for one minute every 30 hours*1 thereafter. When the lamp operation time exceeds 6000 hours*1*2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset. *1: Duration when LAMP MODE of the INSTALLATION menu is set to

LOW. When it is set to STANDARD, this duration will be shorted.

*2: When LAMP MODE is set to STANDARD, this duration will be shorted to 3000 hours.

Important:

•Do not open the lamp cover when the projector is set at a ceiling or a high place. Lamp fragments may fall from the inside if the lamp were broken.

Please contact your dealer when you need to replace the lamp with a new one.

•This projector uses a lamp that contains mercury. Disposal of the lamp or the projector with the lamp may be regulated due to environ- mental considerations.
