Before perform the video system adjustments, check that the data
of page: 0, address: 10 is “00”.
If not, select page: 0, address: 10, and set data “00”
Video system adjustments must be performed in the following or-
der.

Adjusting Procedure:
1. 27 MHz origin oscillation adjustment
2. S VIDEO OUT Y level adjustment
3. S VIDEO OUT chroma level adjustment
4. VIDEO OUT level check

Set the frequency of the clock for synchronization.
If deviated, the synchronization will be disrupted and the color
will become inconsistent.
