Projector Cleaning and maintenance
Cleaning the projector regularly is the most effective way to keep the projector running
normally and prolong the life of the machine. The simplest and most effective method is
to clean the filter regularly and replace the new filter if necessary.
In order to ensure the continuous and stable use of the projector, it is recommended that the
filter be cleaned every three months. If you use projectors in dusty environments, shorten the
cleaning cycle (especially for educational users in schools). When the internal temperature
of the projector is too high, please clean or replace the filter immediately to protect the
projector.
Projector Cleaning and maintenance
• Please turn off the projector and disconnect the power line before cleaning。
• Do not use detergents or solvents.
• After cleaning, before the projector resumes operation, please make sure that there is
no shielding around the projector, and ensure the smooth ventilation .
• After cleaning for a short time still appear overheating hint or found that there is damage
to the filter, please replace the new filter in time.
