This is the ONLY copy of this manual I could find for a realistic price. Even Panasonic could not provide me with one.
The PDF is a very good copy and it helped me diagnose and find the fault with the unit I have.

Very complete and well reading drawings. Documentation is essential for successful repairs.Good documentation, with all that is necessary. This manual was what I was waiting with all the information necessary for the repairing I need it for. You must buy it if you want to do repairs or simply understand how it works.

Excellent service manual includes everything is need to repair this radio-caseete, how to disassemble, wiring diagram, all , waiting time until the download was only a few hours. I'm going to buy service manuals from here, are cheap and very good.Thank you.

Found this to be the manual included with the original packinging, was helpfull but did not give any detailed repair instructions.
CD SECTION
Note: 1. CD Block basically constructed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use the oscilloscope with more than 10 M� impedance. 4. Clean an objective lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. Focus Bias Adjustment Setting: This adjustment is performed with the set placed horizontally.

Focus Gain Adjustment (Coarse adjustment) This adjustment is not required unless the following parts are replaced: � Optical pick-up � RV4 Procedure: 1. Set RV4 to the standard position. (mechanical center) 2. Check whether operation noise (while noise type) caused by the 2-axis device (lens section of the optical pick-up) is abnormally loud. If the operation noise is too loud, turn RV4 slightly counterclockwise. � If the gain is too low: Focus does not function and no music is selected. � If the gain is too high: Noise caused by scratches and dust is heard and the operation becomes unstable. Adjustment Location: servo board Adjustment Location: servo board (component side)
Procedure: 1. Connect an oscilloscope between TP (RF) and TP (RF. GND) on the SERVO board. 2. Connect the power supply. 3. Push the RESET button (S900) on the MAIN board. 4. Insert the disc (YEDS-18) and playback. 5. Adjust RV1 so that the oscilloscope waveform is clear and check RF signal level is correct or not. Note: Clear RF signal waveform means that the sharp �� � can be clearly distinguished at the center of the waveform.
