Conditions (1) Apply 11.50 ± 0.05 [V] on Vcc1-1.
(2) Signals: provide color bar pattern (white 75 %) composite video signal from CP196.
Signal level; 1 Vp-p ± 0.01V (75 ohm termination), conforming to NTSC-M system.
(3) Apply VDD (+5V) voltage on KILLER terminal (CP301) via 22 k resistance.
Adjustment (1) Turn VR305 all the way counterclockwise.
(2) Adjust VR307 so that CP302 voltage becomes 1.83 ± 0.05 [V]. (3) Triggering with CP702 (FRPT), observe CP708 (VG) and adjust VR301 so that White – pedestal level is
2.0 ± 0.05 [V]. (4) Adjust VR305 so that neighboring lines’ white – pedestal is 0.8 ± 0.05 [V]. (5) Observing CP707 (VR), adjust VR309 so that neighboring lines’ white-pedestal level is 0.8 ± 0.05 [V]. (6) Observing CP706 (VB), adjust VR308 so that neighboring lines’ white – pedestal level is 0.8 ± 0.05 [V].
Caution (1) Make sure that waveforms are not distorted.
(2) After the adjustment, remove the resistor connected between CP301 (KILLER) and VDD.

(3) Connect 47kohm resistor between CP304 and CP300 (GND).
Adjustment (1) Triggering CP702 (FRP), observe CP706 (VB) waveform.
(2) Adjust VR302 so that 1, 4 pulses are level. (3) Adjust VR303 so that 2, 3 pulses are level. (4) Adjust VR302 so that 1, 4 pulses are level. (5) Adjust VR303 so that 2, 3 pulses are level.
Caution (1) Be sure that amplitude difference between (1) and (4) pulses is less than 0.1 [V].
(2) Be sure that amplitude difference between (2) and (3) pulses is less than 0.1 [V].
