Adjusting the White Balance

Normally, the document camera automatically adjusts the screen's
white balance. However, it may be necessary to correct for color shifts
in different lighting conditions.
If the displayed image has a color cast, press the
button on the document camera once to correct the color shift. If you
later want to return to automatic white balance adjustment, press the
button a second time. (See page 30 for manual white balance
adjustments using the document camera's on-screen display.)

Rotating the Image

You can rotate the image by 90° in a counterclockwise direction each
time you press the
IMAGE ROTATION
camera. For instructions on rotating the image using the on-screen
display, see page 30.

Reducing Noise in the Image

To reduce noise in the projected image, press the
button on the document camera. To exit this mode, press the button
again.
