· Jig RCU [PTU94023B]
(1) Play back the signal (A1) of the alignment tape (A2).
(2) Apply the external trigger signal to D.FF (E) to observe
the VIDEO OUT waveform and V.PB FM waveform at the
measuring points (D1) and (D2).
(3) Set the VCR to the manual tracking mode.
(4) Adjust tracking so that the V.PB FM waveform becomes
maximum.
(5) Transmit the code (F) from the Jig RCU to adjust so that
the trigger point of the VIDEO OUT waveform is changed
from the trailing edge of the V.sync signal becomes the
specified value (G).
(6) Set the VCR to the stop mode or eject mode.

SECTION 3
ELECTRICAL ADJUSTMENT
Please see Service Manual No. 82848 (HR-S3900U/U(C), HR-S5900U/U(C)).
As for the following items, adjustment is not required or the adjustment has been changed in this model as follows.

D/A level
(1) Insert the cassette tape (A3) to enter the mode (B).
(2) Observe the VIDEO OUT waveform at the measuring
point (D).
(3) Check the Y level value when the External S-input (Y/C
separated video signal).
(4) Switch the input signal to the External input (composite
video signal), and adjust the adjustment part (F) so that
the Y level becomes the same value observed in step
(3).
Note:
· The specified value (G) is just a reference value to be
obtained when the External S-Video (Y/C separated
video) signal is input. In actual adjustment, set it to
the value observed in step (3).

(2) Connect the short wire between the short point (D2) and GND.
(3) Connect the short wire between the short point (D3) and GND.
(4) Connect the short wire between the short point (D4) and GND
in order to reset the microprocessor of the SYSCON.
(5) Disconnect the short wire of step (3).
(6) Adjust the Adjustment part (F) so that the output fre-
quency becomes the specified value (G).
