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.
Thanks.

CD SECTION
Note: 1. Perform all CD section check in the CD Test Mode. (Refer to page 16) 2. Use the PATD-012 disc (Part No.: 4-225-203-01). 3. Use an oscilloscope with more than 10 M� 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.
Checking Location: � CD Board (Conductor Side) �
Procedure: 1. Connect an oscilloscope to TP (TE) and TP (VC) on the CD board. 2. Load the disc (PATD-012). 3. Press the three buttons of x , [MODE/DIR] and [CLOCK] simultaneously to enter the CD Test Mode and display �88� (Initial mode). 4. Press the CD u button to enter the FOCUS1 mode and display �F-�. 5. Confirm that the center level of waveform is 0 V. 6. Confirm that the Vp-p value of waveform is 0.35 to 1.1 V.
VOLT/DIV: 0.2 V (with the 10:1 probe in use) TIME/DIV : 1 ms
Procedure: 1. Connect an oscilloscope to TP (RF) and TP (VC) on the CD board. 2. In the FOCUS1 mode, press the CD u button to enter the ALL SERVO mode and display �P-�. 3. Confirm that the oscilloscope waveform is as shown in the below figure. (eye pattern) A good eye pattern means that the diamond shape ��� in the center of the waveform can be clearly distinguished.
VOLT/DIV: 0.2 V (with the 10: 1 probe in use.) TIME/DIV: 200 ns
0.6 to 1.2 Vp-p
When observing the eye pattern, set the oscilloscope for AC range and raise vertical sensitivity.
