Using the Document Camera
Zooming and Focusing Your Image
Use the
Tele
button on the document camera or remote control to
enlarge the image, and use the
Wide
button to reduce it. The
document camera will automatically focus the image.
If you change items on the stage, press the
AF
button on the remote
control or the
AUTO FOCUS
button on the document camera to
focus the image. The indicator light on the document camera flashes
until the image is focused.
The following objects may not focus well using the auto focus feature:
■
Objects with little contrast
■
Objects with a bright background or excessive contrast
■
Objects with fine repeated patterns or stripes
■
Objects that glitter or reflect bright light
■
Objects with varying depths of field
To manually focus these objects, use the
NEAR
or
FAR
button on the
remote control. Additionally, use these buttons if you want to focus
on a particular part of a three-dimensional object on the stage.

The auto focus function
works up to a height of
approximately 3.9 in.
