Part of my image is blurred or out of focus. What should I do?

• Try the following:
  • If the surroundings are dark and the contrast in the projected image is low, the document camera's auto focus may not work correctly. Press the Focus buttons on the remote control, and then adjust the contrast manually.
  • Make sure the camera head is at least 10 cm (4 inches) away from the object you are viewing.
  • If you are using a projector to display the image, check its focus.
