■
Since the S16C chassis has a built-in single focus circuit, take care when adjusting the focus. When the CRT PCB, FBT or
CRT has been replaced, the focus has to be adjusted according to the following procedures.
1. Display the CROSS Hatch pattern.
2. Set the Screen Adjustment to "View as Standard".
3. Turn the Static Focus VR clockwise to the maximum position.
(End of clockwise direction)
4. Slowly turn the Static Focus VR counter clockwise so that the center vertical line
is the most clearly displayed. [adjusted point : Center(2/1)]
5. Check the entire screen focus and repeat steps 3 to 4, if necessary.
