Buen manual de instrucciones
Las leyes obligan al vendedor a entregarle al comprador, junto con el producto, el manual de instrucciones NAD T747. 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 NAD T747 o vídeos de instrucciones para usuarios. La condición es que tenga una forma legible y entendible.

- marcas de seguridad y certificados que confirmen su concordancia con determinadas normativas
¿Por qué no leemos los manuales de instrucciones?
Normalmente es por la falta de tiempo y seguridad acerca de las funcionalidades determinadas de los dispositivos comprados. Desafortunadamente la conexión y el encendido de NAD T747 no es suficiente.

Al final, en un manual se pueden encontrar los detalles de servicio técnico NAD en caso de que las soluciones propuestas no hayan funcionado.
