This article introduces the use and maintenance of projectors, including mechanical, optical system, lamp source and circuit parts.
The document explains how to protect a projector from dust, vibration, and temperature problems. It stresses keeping the ventilation openings clear, regularly cleaning the intake filter mesh, and ensuring proper airflow to avoid overheating of the LCD panel and lamp.
It also covers safe handling of the lamp, proper grounding of power and signal cables, and how to prevent signal degradation over long cable runs by adding a signal amplifier. Safety warnings include avoiding hot‑plugging cables and never opening the projector yourself because of high‑voltage components. This manual is written in Chinese.

Because the lamp filament is semi‑melted and can explode, which may damage the projector.
Add a signal amplifier after the source; this keeps the signal quality good for distances over 20 m.
Regularly clean the intake filter mesh and make sure the air inlet is not blocked.
