Attaching the Long Life Filter Unit (optional)

to the projector or the Replacement Filter Unit (Model No.: ET-EMF330) (accessory/optional accessory). The
interval to perform maintenance/replacement of filters is extended roughly two times by attaching the Long Life
Filter Unit instead of the standard air filter unit.
When purchasing the optional Long Life Filter Unit (Model No.: ET-EMFU330), consult your dealer.
