"Computer" or "PC".

composite video cable, or HDMI cable. Press the [Menu] button and
select
Function

Image Quality Problems
The image is fuzzy or out of focus
•
The document camera needs hard edges or sharp lines in the image to
be able to focus properly. If the image has only soft edges, try placing a
different document under the camera lens while adjusting the focus. Or
focus the image manually with the
Focus
adjustment in the
Image
menu.
s
•
Make sure the lens is at least 10 cm (4 inches) away from the object
you're viewing.
•
If you're using a projector to display the image, check its focus.
The image brightness or color isn't correct
•
To illuminate your document, slide the lamp switch on the side of the
camera head.
•
Press the [
] or [
] button to increase or decrease image brightness.
•
Set the
White Balance
setting to
Auto
to adjust the color automatically.
s
If the color is still not correct, choose the setting for the type of
lighting you're presenting under (
Cloudy
,
Daylight
,
Fluorescent
, or
Incandescent
).
•
If the document camera was used with a microscope, be sure to turn
the
Microscope
setting off when you return to displaying ordinary
documents.

Other image problems
