Screw the lock ring back onto the lens mount ring and screw both back onto the camera.
Adjust focus by loosening the lock ring and rotating the lens mount ring to adjust the
lens-to-CCD distance.

To re-install the IR filter or other filters, reverse the above procedure.

7.1.7.

Cleaning the CCD faceplate

CAUTION: The CCD faceplate is a high-quality, coated optical surface and
should only be cleaned by authorized, DVC personnel.

If  contamination  of  the  CCD  faceplate  is  suspected,  DVC  strongly
recommends returning the camera to the factory for professional cleaning.
Scratches,  chemical  contamination,  or  other  damage  due  to  improper
cleaning may void the camera warranty.
