Register 24 (OP4):
This register has CC line number - (Low nibble to 60Hz and high nibble to 50Hz)
The Bits 0,1,2,3 are used to select the line where Closed Caption information will be extracted when in
60Hz, and the bits 4, 5, 6, 7 are used to select the line where Closed Caption information will be extracted
when in 50Hz
Note:
This information is used by microcontroller.

3. Geometry of the Image
a) Using the PM - 5515 generator, apply the crosshatch pattern with circle.
b) Adjust the following items:
Vertical slope (VSl);
Height (VAm);
Vertical position (VSh);
Center Linearity (VSc);
Horizontal position (HSh)
Adjust the above items, until obtaining the best circle symmetry and positioning, as well as the
minor image geometric distortion.
