Figure 21. Video Pattern for Horizontal Gain Cursor

Note that these controls only modify the video signals. They have no effect on the conver-

gence signals. The dedicated controls of the convergence signals are described in Section 9.7

"MANUFACTURING, AFTER-SALES SERVICE, LAB TRIAL MODES" on page 49.

7.5.2 Video Pattern for Vertical Gain Cursor

The video pattern for the vertical gain cursor is identical to video pattern for the horizontal gain

cursor (displayed at the centre of the visible grid), except for one horizontal line which is added

only in the even TV field.
