Correcting The Focus - Panasonic PT-EX12KU Operating Instructions Manual

Correcting the focus

When the lens is attached to the projector and images are being projected onto the screen, the peripheral focus
may be out of focus in some areas. If this happens, insert the supplied spacer between the lens attachment and
the lens to adjust the focus.
Inserting the spacer corrects the distance on the lens adjustment and improves the diagonal focus. The corrected
distance is determined by the thickness of the spacer to be inserted. As a guide, the corrected distance is
approximately 30 mm by 0.1 mm in the thickness of the spacer.
Three types of spacers, four for each spacer type, are supplied. Insert these spacers to correct the distance as
required.
