This was precisely what I was looking for. Complete and good quality!

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.
