When I purchased this manual I had my doubts regarding the quality as the price was so reasonable as compared to other outlets.
The manual itself is of high standard the print is very clear as are the diagrams. Obviously with the diagrams one has to zoom in otherwise it is to small to be able to read.
Overall I am very pleased with the company who delivered as they said and with the manual they supplied.
I occasionally require a manual and now having registered with this company I shall order from them in the future.
I was at first dubious about payiong for downloaded manuals but having done so, I was extremely impressed with quality of the two manual I ordered, well worth the small price I paid.
I would highly recommend these to my friends.
reasonable price for the schematic - the service is perfect, all as expected and pointed by instructions - good scan of the original plans - thank you!
Manual was just as described!!! I odered it and in less than a day was able to download it and the text was clear and pages were all complete just as the original manual was. Purcashed this for a friend and they were more than happy. Perfect all around!
Excellent service and prompt delivery. But it's not a manual - only 4 pages wiring diagrams.
3. Mode: Playback
test tape P-4-A100 (10 kHz, â10 dB) L-CH MAIN board CN510 R-CH pin 3 waveform of oscilloscope
CD SECTION [TEST DISC LIST]
pin 1 L R pin 2 V H oscilloscope
Use the following test disc on test mode. â¢ CD: YEDS-18 (PART No. 3-702-101-01) or PATD-012 (PART No. 4-225-203-01) Note: 1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10MW impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks.
in phase 45Â° good
90Â° 135Â° 180Â° wrong
4. After the adjustments, apply suitable locking compound to the pats adjusted.
BD91 board oscilloscope
Adjustment Location: Playback Head (Deck A). Record/Playback/Erase Head (Deck B).
Procedure : 1. Connect an oscilloscope to TP106 (FE) and TP124 (VC). 2. Turn the power on. 3. Load a disc (YEDS-18) and actuate the focus search. (In consequence of open and close the disc tray, actuate the focus search) 4. Confirm that the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 3 Â± 0.5 Vp-p.
S-curve waveform symmetry
within 3 Â±0.5Vp-p B
Note: â¢ Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. â¢ Take sweep time as long as possible and light up the brightness to obtain best waveform.
