Notes

•If you raise up the arm while the camera input is being selected, the color of the picture may vary for an instant due to the automatic white balance adjustment. This is not a malfunction.

•If you put the arm back and raise it again while the white balance is locked (the LOCK indicator is lit), the projector will release the white balance.

•Depending on the tint of the indoor illumination, the white balance might not be compensated optimally. Should this be the case, or if you would like to adjust it to a desired tint, adjust “R-level”, “G-level” or “B-level” on the FULL MENU [Color] screen.
