Check the level B of the oscilliscope's waveform and the A
(DC voltage) of the center of the Traverse waveform.
Confirm the following :
A/B x 100 = less than ± 22%
Traverse waveform

button. (The tracking servo and sledding servo
are turned ON.) Confirm the C (DC voltage) is almost equal to
the A (DC voltage) is step 6.
