Notes
. For this adjustment, using an 89.9 % - reflective grayscale chart is preferable. (Refer to Section 3-1-5.)
. Make sure that presetting all the compensation data is completed before beginning adjustment.
(Refer to Section 3-1-4.)
. This adjustment must be done at Field Rate 60 (for BVP-9500WS) or 50 (for BVP-9500WSP) : x1
