■Correcting illuminated defects

In rare cases, a portion of the pixels of CCD image sensor used by the camera could be damaged by cosmic rays and the like. This damage could cause white spots (illuminated defects) to appear on the screen. If illuminated defects appear in the images of the document camera, correct them as follows:

1With the document camera in use, cover the

camera lens completely with black paper, cloth, or the like.

control buttons cannot be used.) The illuminated defects are corrected.
