Method of Auto RGB Color Balance (1) Input RGB Source : 16 Gray Scale Pattern output (RGB output Level : 0.7Vp-p) (2) Press ADJ KEY on R/C for adjustment. (3) Press Vol. + KEY and operate To SET. (4) Auto-RGB OK means completed adjustment. 8. Auto Component Color Balance 8-1. Pattern Equipment MSP3240A or same product (16 Gray Scale Pattern output(Component output Level: 0.7Vp-p) 8-2. Method of Auto RGB Color Balance (1) Input RGB Source : Component 480p/576p 16 Gray Scale Pattern At this time, except Pb and Pr signal, only Y signal insert. (2) Press ADJ KEY on R/C for adjustment. (3) Press Vol. + KEY and operate To set. (4) Auto-RGB OK means completed adjustment. 6-3. Adjustment of White Balance O Operate the Zero-calibration of the CA-100, then stick sensor to PDP module surface when you adjust. O For manual adjustment, it is also possible by the following sequence. (1) Select white pattern of heat-run mode by pressing power on key on remote control for adjustment then operate heat run more than 15 minutes.
