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.
Note: 1. CD Block is basically constructed to operate without adjustment. Therefore, check each item in order given. 2. 3. 4. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. Use an oscilloscope with more than 10Mâ¦ impedance. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. Adjust the focus bias adjustment when optical block is replaced.
RF Level Check
CD DECODER board TP (RF) CN12 (VC) oscilloscope
Procedure : 1. 2. 3. 4. Connect oscilloscope to test point TP (RF) on CD DECODER board. Turned Power switch on. Put disc (YEDS-18) in and playback. Confirm that oscilloscope waveform is clear and check RF

signal level is correct or not. Note: Clear RF signal waveform means that the shape âââ can be clearly distinguished at the center of the waveform.
VOLT/DIV: 200 mV TIME/DIV: 500 nS level: 1.0 â0.2 Vp-p
Procedure: 1. Connect DC voltmeter to test point CN12 (FEO), (VC) on CD DECODER board. 2. Turned Power switch on. 3. Put disc (YEDS-18) in and stop. 4. Adjust VR01 so that the DC voltmeter reading is 0 Â± 20 mV. Adjustment Location: CD DECODER board
Adjustment Location: CD DECODER board
Focus Gain Adjustment (VR02) This gain has a margin, so even if it is slightly off. There is no problem. Therefore, do not perform this adjustment. Please note that it should be fixed to mechanical center position when you moved and do not know original position.
