3-3. SERVO SYSTEM ADJUSTMENTS
Before perform the servo system adjustments, check that the speci-
fied values of “28 MHz Origin Oscillation Adjustment” of “VIDEO
SYSTEM ADJUSTMENTS” is satisfied.
Check that the data of page: 0, address: 10 is “00”.
If not, select page: 0, address: 10, and set the data “00”.
