3.4 MECHANISM COMPATIBILITY ADJUSTMENT
3.4.1 Tape pattern check
(1) Connect the JIG CONNECTOR CABLE to the set.
As for the connection procedure, JIG CONNECTOR
BOARD and see 3.5 ELECTRICAL ADJUSTMENT.
(2) Remove the COVER(ADJUST)
(3) Play back the compatibility adjustment tape.
(4) While triggering the HID1, observe the waveform of
ENV_OUT.
(5) Confirm that the waveform is free from remarkable level-
down, and entirely parallel and straight.
(6) In case any level-down is observed on the left hand side,
straighten the level by turning the GUIDE ROLLER (SUP)
of the POLE BASE ASSEMBLY.
In case any level-down is observed on the right hand side,
however, straighten the level by turning the GUIDE ROLL-
ER(TU) of the POLE BASE ASSEMBLY.
(7) After adjustment, try the unloading motion once, and con-
firm that the waveform is flat (straight) when the tape has
been played back again.
Moreover, perform readjustment as required.
(8) When the recording has been played back again, play back
the self-recording to confirm that the waveform is flat.
