(2). Set the picture condition on “APC ON” (CLEAR) mode.
(3). Press the “ADJ” key of the factory remote control three
times to enter to “
SUB-TINT
” adjustment mode.
(4). Change the Sub-Tint data by pressing the VOL

Key
until the upper and lower CYAN color becomes same color.
3.7. Deflection Setting Data Adjustment
These adjustment will be done by Auto Adjustment Equipment.
For manual adjustment, it is also possible by the following
procedure.
3.7.1. Adjustment Preparation

Key to change the data.
3.7.2. Adjustment
(1) V SLOPE
Half of the picture (bottom part) changed to blank.
Adjust so that half blanked- Picture bottom line in accord
with geometric vertical center of the CPT.
(2) V SHIFT (Vertical Shift)
Adjust so that the horizontal center line of a digital circle pattern
is in accord with geometric horizontal center of the CPT.
(3) V LINEAR (Vertical Linearity)
Adjust so that the boundary line between upper and lower
half is in accord with eometric horizontal center of the CPT
(4) V AMPLIT (Vertical Amplitude)
Adjust so that the circle of a digital circle pattern may be
located within the effective screen of the CPT.
(5) H SHIFT (Horizontal Shift)
Adjust so that the Horizontal center line of a digital circle
pattern is in accord with geometric vertical center of the CPT.
(6) EW WIDTH (Horizontal Width)
Adjust to that a digital circle pattern looks like exact circle.
(7) EW PARAB (East-west PARABOLA)
Adjust so that middle portion of the outer most left and
right vertical line looks like parallel with vertical lines of
the CPT.
(8) EW TRAPE (East-west TRAPEZOID)
Adjust to make the length of top horizontal line same
with it of the bottom horizontal line.
(9) EW UPCOR
Adjust until symmetries upper corner of the screen.
(10) EW LOCOR
Adjust until symmetries upper corner of the screen.
