eplacing the Filter
After using the projector for 2,000 hours, it is necessary to replace the filter. If the filter is not cleaned, it can be dusty and prevent proper
ventilation. This will cause overheating and a malfunction of the projector. (In case that the projector is located at a dustier environment, you
may also consider to replace the filter at every 1,000 hours.)
