Equipment: Color bar chart (3200°K),
Vector scope, Wave form monitor.
Set AGC and White balance switches to Manual side
(push down ).
Use standard Fujinon lens (Calibrated ) and set the iris
to F=8.
Burst level
Adjust VR6 so that burst level on Vector scope is on the
75 % line or 286±15mV. If Burst vector is not stable, add
a 22pf capacitor to crystal capacitor. Make sure to select
the right value of C5 located at Driver board.
4.2 PREPARATION
