3.1.4 Jig connector cable connection
3.1.4.1 Preparation
The Jig connector cable (YTU93106B) has been provided for
GR-DV2000 series. And it has been connected only 9 termi-
nals for low cost, although it has 30 terminals.
Now it can be used another series camcorder, but all the
terminals have to be connected by soldering wires. Refer to
the Service Bulletin (No. YA-SB-10082), and connect all the
terminals.

3.2 Mechanism compatibility adjustment
3.2.1 Tape pattern check
(1) Play back the tape for compatibility adjustment.
(2) Apply the external trigger signal to HID1, to observe the
waveform of the ENV_OUT.
(3) Set to the manual tracking mode (ATF OFF).
(4) Make sure that there is no significant level drop of the
waveform caused by the tracking operation, with its gen-
erally parallel and linear variation ensured. Perform the fol-
lowing adjustments when required.
(5) Reduce the waveform by the tracking operation. If a drop
in level is found on the left side, turn the guide roller (sup-
ply side) to make the waveform linear.
If a drop in level is on the right side, likewise turn the guide
roller (take-up side) to make it linear.
(6) Unload the cassette tape once, play back the tape again
and confirm that the waveform is flat.
(7) Record at the recording tape, and play back the recorded
signal.
(8) Confirm that the waveform is flat.
