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
.
