jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
 ;
Wszystko w porządku.
Instrukcja czytelna i kompletna.
Dziękuję.
all right!
thank you.
;
Bardzo dobra instrukcja. Zawiera wszystko co potrzeba, polecam!
;
Instrukcja jest OK. Schematy czytelne, opisane niektóre procedury.
