Ys, Yn, Yp, Yo:
These are all Y-delay adjustment for various systems. (Y-delay
adjustment for SECAM, Y-delay adjustment for NTSC, Y-delay adjustment for
PAL, Y-delay adjustment for external sources). Colours interferences could be
prevented by these bits.
Connect a pattern to TV set and set pattern colour bar.
These bits could narrow junction line of colours.
8.4 OTHER ADJUSTMENT VARIABLES
CL:
Cathode drive Level, picture quality could be improved by changing this
level. There could be paled colours by time. This properties help to revive.
TXT-CL:
Teletext Cathode drive Level, teletext mode and TV mode are completely
different from each other, so this adjustment should be repeated for
teletext mode.
H vol:
Hotel Mode volume adjustment could be achieved. (Hotel Mode Volume)
