MAINTENANCE

This projector only needs simple maintenance.

1.Keep the lens clean so that the shadow of dust or stains will not appear on the screen.

2.Clean the air filter located at the bottom of the projector. If the air filter is blocked by dust, this will cause bad ventilation. Thus, the life of the projector will be shortening, and malfunctions will occur due to overheating.

Attention: When cleaning any section of the projector, the power should be turned off, and the power cord should be unplugged.

Warning: Never open or try to open any covers of the projector except the cover of the lamp, filter, and lens. When the projector is operated, it emits high voltage of electricity and heat. Improper operation will cause you severe injury. Except what is specifically indicated in this manual, never try to do any other maintenance. You should have qualified service personnel conduct any service maintenance.
