• Please carefully read the "User's Manual - Safety Guide.
• Before caring, make sure the power switch is off and the power cable is not plugged in, then wait at least
45 minutes for the lamp to cool suffi ciently.
• Use only the air fi lter of the specifi ed type.
• Do not use the projector with the air fi lter and fi lter cover removed. The use without the air fi lter could
result in damage.

Caring for the Air filter
The item "FILTER MESSAGE" in the "OPTION" menu enables users to select the timer for the interval to
show the message for cleaning up the air filter. It is recommended to choose "100h" in general. Please be
careful with the operating environment of the projector and the condition of air filter, especially when "200h",
"300h" or "TURN OFF" is chosen. Please check and clean the air filter periodically, even if there is no
message.
If the air filter becomes blocked by dust or others, the internal temperature will rise, which could cause
malfunction, or reduce the lifetime of the projector.
If the soiling will not come off the air filter, or it becomes damaged, then it needs to be replaced. Please
replace the air filter as soon as possible.
