(CH-1 trigger slope switch at (+),<br />
Internal trigger at CH-1 side.)<br />
6.5 ± 0.5H (lines)<br />
1. Insert the Aligment Tape (VRO-CBZF) and set to PB Mode.<br />
2. Transmit the TEST code (R/C code 47H) to <strong>VC</strong>R.<br />
Or, once, short the TP801 at the main PWB<br />
(By doing this,LCD will all light up and become the PB<br />
Tracking Center value.<br />
~ As for the recover equipment,prepare the memory-remote<br />
control.<br />
But,while adjust the running, at non cassete control unit<br />
condition but have the cassete control JP(TP801 short on<br />
the main PWB), if press TRACKING UP and DOWN key at<br />
the same time, it'll become the TRACKING CENTER (for<br />
Running Ajustment)<br />
3. Again, transmit the PLAY (PB), or Press PLAY Key.After<br />
AUTO PG ADJ mode is finished, make sure the PB Switching<br />
Point is inside standard range.<br />
~ During Flashing of PLAY(casette mark) is AUTO PG ADJ,<br />
finish the AUTO PG ADJ,by light off.<br />
~ When using the manual PG ADJ,finish the No.2, and it is<br />
able to adjust the PG using FF key or REW key.<br />

1. PB the self-REC tape.<br />
2. Set to SLOW PB mode by pressing the SLOW key.<br />
3. Transmit the TEST(R/C code 47H).Or short the TP801<br />
on the main PWB once.<br />
4. Adjust the noise bar at the botton of monitor screen<br />
using TRACKING UP,DOWN key until it dissapear.<br />
5. Press the PB key to PB and during this time, press the<br />
PB/STILL for few times repeatedly and during STILL<br />
make sure no noise appear.<br />
Same with the SP, do the 1~5 items.(for LP )<br />

3. As looking at the monitor, using the TRACKING UP+,<br />
DOWN− adjust till the perpendicular jitter dissapear.<br />
~ For the LP also, while PB the self-REC tape, for STILL,<br />
it is better to confirm that no perpendicular jitter appear.<br />
