ADJUSTMENT

1.REGULATED B + ADJUSTMENT (VRSOl)

Connect high impedance voltmeter between TR901 emitter and ground rotate the B + adjustment control (VR901) to obtain a reading of

12.02 O.lV.

2.FOCUS (VR704)

Adjust the focus control (VR704) for best overall focus of the test pattern (marked with the symbol “%“). Usually the center and corners of the screen do not focus at the same setting and a compromise must be made.

3. VERTICAL SIZE (VR601)

The vertical size control (VR601) should be adjust for the picture to fill the screen vertically.

4. HORIZONTAL SIZE (L703)

The horizontal size control (H-site coil) should be adjusted for the picture to fill the screen horizontal- ly.

5. HORIZONTAL POSITION NR701)

The horizontal position control (VH701) snould be adjusted for the horizontal picture position.

6.SUB-BRIGHT (VR703)

Adjust subbright control (VR703) for visual cut off of the raster when external brightness is turned to maximum

7.CENTERING ADJUSTMENT

It the raster is not centered horizontally and verti- cally it may be centered by removing the cabinet back and adjusting the centering tabs on the neck of the tube, located at the rear of the deflection yoke. Turn the whole device clockwise or counterclockwise. To increase the amount of raster shift move the two tabs which project from the device farther apart, if raster is tilted on an angle, it may be straightened by loosening the deflection yoke clamp and rotating the deflection yoke.
