Locking the white balance
Although the projector’s camera is constantly adjusting the color balance of the images
it photographs, the color balance may be disrupted, depending on the color layout of
the document. If this happens, the white balance can be locked using the procedures
below.
1
Lay down a piece of white paper, and adjust so it fills the screen.
Adjust the camera head and arm so that the white
paper fills the screen completely.
2
Set the White balance to Lock in the Image adjustment menu.
The white balance is locked. If you want to return to the auto adjustment, set the White
balance to Auto in the Image adjustment menu.
Notes
• If the white balance is set to Lock, once power is turned off, the setting goes back to
Auto.
• The color of the room lighting may prevent the white balance from being adjusted to the
optimum level. In this situation, or if you want to use a certain tinting, adjust the R-level,
G-level and B-level on the Image adjustment menu
.
