(1) Play back the compatibility adjustment tape.CABLE CONNECTION".
(2) While triggering the HID1, observe the waveform of
ENV_OUT.
(3) Set the manual tracking mode (ATF OFF).
(4) Confirm that the waveform is entirely parallel and straight,
and free from remarkable level-down, through the tracking
operation.
Make the confirmation as follows if necessary.
(5) If level-down is observed on the left hand side of the
waveform, straighten the level by turning the GUIDE
ROLLER (SUP).
If level-down is observed on the right hand side of the
waveform, straighten the
level by turning the GUIDE ROLLER (TU).
(6) After the adjustment, try the unloading motion once, and
confirm that the waveform is flat when the tape has been
played back again.
(7) Play back the self-recording.
(8) Confirm that the waveform is flat.
Flatten the waveform.
