NOTES ON USE
• The projector uses a high-voltage mercury lamp that contains high internal pressure. This lamp may break,
emitting a large sound, or fail to illuminate, due to impact or extended use. The length of time that it takes
for the lamp to break or fail to illuminate varies greatly depending on individual lamp characteristics and
usage conditions.
• The brightness of the lamp will gradually decrease with use.
• The lamp, LCD panel, polarizing plate, and polarizing beam splitter (PBS) are consumable parts. These parts
may need to be replaced during the guarantee period if the projector is used for six or more hours per day.
• The replacement cycle of the LCD panel, polarizing plate, and polarizing beam splitter (PBS) will be short-
ened if the projector is subjected to continuous use for six or more hours. Likewise, the replacement cycle
of the lamp will be shortened if the power is frequently turned on and off or the projector is subjected to
continuous use for 10 or more hours.
• Interruptions may occur in the wireless connection due to signal interference or PC conditions.
