Fully functional usable service manual. Considering the age of the manual and device quality was better than expected
 ;
Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!
;
It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!
;
Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.
;
As the only source for this manual it rather rank quite high since it is well scanned and perfectly readable.

VOLT/DIV : 0.2V TIME/DIV : 2mS
VOLT/DIV : 0.2V TIME/DIV : 2mS
4-3-3 To Adjust Focus Gain (PLAY mode)
1. 2. 3. Connect the GND terminal of the oscilloscope to Vref and (+) terminal to AP1. Load and play the disc While the disc is running adjust the gain with WVR2 as shown in the following figure. Normal frequency Low frequency High frequency
---250mV ---100mV ---0 V ---0 V ---100mV ---0V
VOLT/DIV : 0.1V TIME/DIV : 2mS

4-3-4 To Adjust E/F Balance (PLAY mode)
1. 2. 3. Set TIME/DIV of the oscilloscope to 2mS. Set Volt/DIV of the oscilloscope to 0.5V. Ground the scope input and set to DC and then set the DC range. Connect the GND terminal of the oscilloscope to Vref and (+) terminal to center to AP2. Load and play the disc. Turn WVR1 counterclockwise to the minimum value. Raise WVR3 and adjust the waveform so that its middle comes to GND of the oscilloscope (or until the upper half of waveform becomes symmetrical to the bottom half, A=B) Adjust WVR1 (arrow) for normal sound.
4-3-1 To Adjust FOCUS BIAS(STOP mode)
1. 2. 3. 4. Set Volt/Div of the oscilloscope to DC 100mV. Ground the scope input and set the waveform to 0V, DC range. Connect the GND terminal of the oscilloscope to Vref, and (+) terminal to center of AP1. Set WVR4 to 0mV.
