Buen manual de instrucciones

Las leyes obligan al vendedor a entregarle al comprador, junto con el producto, el manual de instrucciones Agilent Technologies U2781A. La falta del manual o facilitar información incorrecta al consumidor constituyen una base de reclamación por no estar de acuerdo el producto con el contrato. Según la ley, está permitido adjuntar un manual de otra forma que no sea en papel, lo cual últimamente es bastante común y los fabricantes nos facilitan un manual gráfico, su versión electrónica Agilent Technologies U2781A o vídeos de instrucciones para usuarios. La condición es que tenga una forma legible y entendible.
