A condição é uma forma legível e compreensível.

O que é a instrução?

A palavra vem do latim "Instructio" ou instruir. Portanto, no manual Oki 721 você pode encontrar uma descrição das fases do processo. O objetivo do manual é instruir, facilitar o arranque, a utilização do equipamento ou a execução de determinadas tarefas. O manual é uma coleção de informações sobre o objeto / serviço, um guia.

O manual contém uma série de orientações sobre funcionalidades específicas, a segurança, os métodos de manutenção (mesmo sobre produtos que devem ser usados), possíveis defeitos Oki 721 e formas de resolver problemas comuns durante o uso. No final, no manual podemos encontrar as coordenadas do serviço Oki na ausência da eficácia das soluções propostas.
