Interval of lamp replacement

The recommended interval of lamp replacement is about 2,000 hours of consecutive use. Such interval differs depending on the operating environment and may be shorter than 2,000 hours. Decrease in lumi- nescence and/or color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 1,500 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 1,900 hours*1, the replacement message (LAMP:>1900H) will appear on the screen for one minute every 10 hours thereafter.

When the lamp operation time exceeds 2,000 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 When LAMP MODE of the INSTALLATION menu is set to STANDARD.

*2 When LAMP MODE is set to LOW, this duration will be extended up to 5,000 hours.

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