Notes
•When dirt and dust build up in the air filter, the air circulation inside the projector is affected and the internal temperature will rise, causing the projector to stop working or malfunction.
•Push the air filter fully in. If the projector is used with the air filter only partially inserted, dust and dirt will enter the interior and this could cause the projector to stop working or break down.
•If you wash the air filer with water, make sure to dry it completely before replacing it.
•If the air filter becomes damaged, replace it. Contact your sales representative for a new filter. If you continue to use the projector when its filter is damaged, dust and dirt will enter the interior and this could cause the projector to stop working or break down.
