NOTE: Prior to the adjustment, remove the COVER (ADJ). (1) Play back the compatibility adjustment tape. (2) While triggering the HID, 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). For actual adjustment, first, turn both the GUIDE ROLLERS (SUP and TU) to tightening direction (clockwise) in order to misalign the waveform once. Next, turn the GUIDE ROLLERS to returning direction (counterclockwise), then stop turning at the point where the waveform becomes flat. Turn only the GUIDE ROLLER (SUP) further more, then stop turning at the point where the waveform starts changing. (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.
