Roll-up filter
This projector is equipped with a roll-up filter. The 
clogged filter rolls and replaces with a clean one 
periodically. When all the filters are rolled up, you can 
replace the filter cartridge with a new one. 
•  When the power of the projector is on, the filter
rolls after the designated time elapses. 
•  There are 10 filters per cartridge. When a filter rolls,
REMAINING FILTERS is decreased and FILTER 
USAGE TIME is reset.
Important:
•  When REMAINING FILTERS reaches 0, the FILTER 
indicator blinks red. In this case, prepare a new filter 
cartridge. When the last filter is clogged, replace the 
filter cartridge. For details, contact your dealer.
•  Depending on the ambient environment, the filter
may run out before rolling 9 times and the FILTER 
indicator may blink orange while the projector is 
turned on. In this case, replace the filter cartridge. 
For details contact your dealer.
