It is definitely necessary to keep a projector clean for its reliable use. Cooling fans and their shield
should be cleaned every 15days. LED lamps’
lens and cover should be cleaned regularly for
optimized light output.
Cleaning frequency depends on how often a projector is used and its operational environment. A
soft cloth and typical glass cleaning products should be used. It is recommended to clean the
external optics at least once every 20 days.
Do not use any organic solvent, e.g. alcohol, to clean t housing of the apparatus.
