[. . . ] Adjust Y-Delay for PAL till the colour transients on the colour bar of the pattern become as sharper and colours between transients do not mix with each other as possible. 23 AK - 45 CHASSIS Y-Delay SECAM Enter a SECAM B/G colour and black-white bar test pattern via RF. Adjust Y-Delay SECAM till the colour transients on the colour bar of the pattern become as sharper and colours between transients do not mix with each other as possible. Y-Delay NTSC Enter an NTSC colour and black-white bar test pattern via RF. Adjust Y-Delay NTSC till the colour transients on the colour bar of the pattern become as sharper and colours between transients do not mix with each other as possible. Vertical Position Offset This value is fixed (127) Vertical Position Offset This value is fixed (127) Horizontal Position Offset This value is fixed (127) Horizontal Position Offset This value is fixed (127) Vertical Blank Start This register will be used only at 4:3 tubes for 16:9 mode adjustment. Vertical Blank Stop This register will be used only at 4:3 tubes for 16:9 mode adjustment. Angle Change Angle by pressing Left/Right buttons till the vertical lines of the crosshatch pattern become completely perpendicular to horizontal lines without any angle of vertical deviation. Check and readjust ANGLE item if the adjustment becomes improper after some other geometric adjustments are done. Bow Change Bow by pressing Left/Right buttons till the vertical lines especially ones close to the left and right sides will of equal and symmetrical bending, i. e. Check and readjust BOW item if the adjustment becomes improper after some other geometric adjustments are done. 4:3 Horizontal Blank Start This register will be used only at 16:9 tube for 4:3 mode adjustment. 4:3 Horizontal Blank Stop This register will be used only at 16:9 tube for 4:3 mode adjustment. EHTV Compensation It's used to adjust the EHT compensation vertical gain coefficient. EHTTM Compensation It's used to adjust the EHT compensation time constant. EHTEW Compensation It's used to adjust the EHT compensation east/west gain coefficient. 24 AK - 45 CHASSIS WDR The amplitude of R of RGB output can be adjusted with the drive parameter WDR. WDG The amplitude of G of RGB output can be adjusted with the drive parameter WDG. WDB The amplitude of B of RGB output can be adjusted with the drive parameter WDB. CR The DC offset values of R of RGB output can be adjusted with the cutoff parameter CR. CG The DC offset values of G of RGB output can be adjusted with the cutoff parameter CG. CB The DC offset values of B of RGB output can be adjusted with the cutoff parameter CB. COR coring level The amplitude of the correction signal is adjustable. Small noise amplitudes in the correction signal are suppressed by an adjustable coring circuit.
