Cleaning and replacing the air filter

If the air filter becomes clogged with dust, the internal temperature of the projector will rise, the TEMP indicator will illuminate and the projector’s power will turn off (the TEMP indicator will flash after the power is turned off).

The air filter should be cleaned every 100 hours of use.

Cleaning

Use a vacuum cleaner to clean off any accumulated dust.
