El manual esta muy detallado, los numeros de partes y los esquemas de despiece son correctísimos y muy claros, tanto para los técnicos experimentados como para los novatos.
Very good service Within one day i received a pdf of the users manual and electric circuits so I was able to measure the different voltages in the printed circuit and find out the fault Payment was also reliable and easy.Without the manual i could not have repaired.So thanks to "Search for a manual"
