First, monitor R-output and conduct the following: Vary TINT values and adjust so that oscillation width of each horizontal scanning period would be unified, using UP/ DOWN

21、 keys of remote controller. (Refer to Fig. 1 and Fig. 2.) * In Fig 1, oscillation width of R-output and B-output of hori- zontal scanning period are not unified. In Fig. 2, however, the oscillation width of horizontal scan- ning periods are unified. 4. After adjustment, press final selection key. *
