This site is working fine! Did buy a manual for SX-EX25L and after a while I could download it and fix the problem. Nice and easy!
;
Complete manual as pdf-file in very good quality. Very helpful and fast availability.
;
Complete service manual in very good scanning quality with all schematic and PWB graphics as well as assembly & maintenance instructions. A slight drawback is that the rastering of the PWB graphics sometimes makes it a bit difficult to follow fine traces, but no showstopper.

Purchased the manual that I was looking for at a great price and could download it easily.. Great service experience and for future purchases I plan to use the site. Thank you very much
