De acordo com a lei, pode anexar o manual em uma outra forma de que em papel, o que é frequentemente utilizado, anexando uma forma gráfica ou manual electrónicoYamaha F25 vídeos instrutivos para os usuários. A condição é uma forma legível e compreensível.

O que é a instrução?

A palavra vem do latim "Instructio" ou instruir. Portanto, no manual Yamaha F25 você pode encontrar uma descrição das fases do processo.
