magnetic field effect.
2 piece assembly
For models using 4 pairs of rings, place the yoke on the CRT neck (do not tighten the clamp).
Place the vertical raster shift tabs at 3 o’clock (90° from the purity and convergence tabs.
Description of rings
Initial position of rings
Turn the receiver ON. Operate the receiver for 60 minutes using the first purity check field (white
screen) to stabilize the CRT.
Fully degauss the receiver by using an external degaussing coil.
Slide the deflection yoke back and forth on the neck of the CRT until it produces a near white,
uniform raster.
VERTICAL RASTER SHIFT ADJUSTMENT
Apply a green pattern with a horizontal line, adjust the Deflection Yoke so that has no tilt, then
secure it.
Adjust center line of the pattern with the mechanical center of the CRT, this center is determined
by two marks at the side edges of the screen. To adjust the line, once the vertical raster shift tabs
are place at 3 o’clock to reduce itsmagnetic field effect open the tabs the same angle from the
center, until the center line of the pattern becomes a straight line, centered with the marks of the
CRT.
IMPORTANT NOTICE
Rings come along with deflection yoke in one piece.
