Using the Document Camera 15
Adjusting the Lighting
For presenting printed material or 3-D objects, the two lamps will
provide ample light. If the ambient lighting in the room is sufficient,
however, you may obtain a better image with the lamps off. Press the
Lamp
button on the control panel to turn off the lamps. Press it again
to turn the lamps back on.
Adjusting the Image
Once you see your image, you may need to make certain adjustments:
■
To zoom or focus your image, see the next section.
■
To freeze the image on screen, see page 16.
Zooming and Focusing Your Image
When you turn on the document camera, the Auto Focus feature is
turned on and the indicator light is lit.
Use the
Tele
button on the control panel to enlarge the image, and
use the
Wide
button to reduce it. The document camera will
automatically focus the image. Once the zoom or focus is set for a flat
document, you probably won’t have to adjust it again for subsequent
documents.
