2.8.2 Tape pattern check
(1)
Play back the compatibility adjustment tape.
(2)
While triggering the MAIN CN114-11PIN (HID1), ob-
serve the waveform of CN114-29PIN (ENV_OUT).
(3)
Confirm that the waveform is free from remarkable
level-down, and entirely parallel and straight.
Moreover, perform the following adjustment as re-
quired.
(4)
In case any level-down is observed on the left hand
side, straighten the level by turning the guide roller of
the pole base assembly (supply).
In case any level-down is observed on the right hand
side, however, straighten the level by turning the guide
roller of the pole base assembly (Take-up).
(5)
After adjustment, try the unloading motion once, and
confirm that the waveform is flat (straight) when the
tape has been played back again.
Moreover, perform readjustment as required.
(6)
When the recording has been played back again, play
back the self-recording to confirm that the waveform
is flat.

Note:
When an adjustment is performed with the lower case cover
attached, first slide the Cover (M.ADJ) open and then per-
form the compatibility adjustment.
Be sure not to damage the cover plate when sliding it open
to make an adjustment because it must be re-positioned af-
ter completing the adjustment.
NOTE)
The JIG connector board uses 30 of the 40 pins of
CN114 on the Main board.
Pins 1 to 5, 21 to 24 and 34 of CN114 on the Main board
are not used.
