Buen manual de instrucciones

Las leyes obligan al vendedor a entregarle al comprador, junto con el producto, el manual de instrucciones Meyer Sound M3D-SUB. 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 Meyer Sound M3D-SUB o vídeos de instrucciones para usuarios. La condición es que tenga una forma legible y entendible.

¿Qué es un manual de instrucciones?

El nombre proviene de la palabra latina “instructio”, es decir, ordenar. Por lo tanto, en un manual Meyer Sound M3D-SUB se puede encontrar la descripción de las etapas de actuación. El propósito de un manual es enseñar, facilitar el encendido o el uso de un dispositivo o la realización de acciones concretas. Un manual de instrucciones también es una fuente de información acerca de un objeto o un servicio, es una pista.

Desafortunadamente pocos usuarios destinan su tiempo a leer manuales Meyer Sound M3D-SUB, sin embargo, un buen manual nos permite, no solo conocer una cantidad de funcionalidades adicionales del dispositivo comprado, sino también evitar la mayoría de fallos.

Entonces, ¿qué debe contener el manual de instrucciones perfecto?

Sobre todo, un manual de instrucciones Meyer Sound M3D-SUB debe contener:
- información acerca de las especificaciones técnicas del dispositivo Meyer Sound M3D-SUB
- nombre de fabricante y año de fabricación del dispositivo Meyer Sound M3D-SUB
- condiciones de uso, configuración y mantenimiento del dispositivo Meyer Sound M3D-SUB
- 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 Meyer Sound M3D-SUB no es suficiente. El manual de instrucciones siempre contiene una serie de indicaciones acerca de determinadas funcionalidades, normas de seguridad, consejos de mantenimiento (incluso qué productos usar), fallos eventuales de Meyer Sound M3D-SUB y maneras de solucionar los problemas que puedan ocurrir durante su uso. Al final, en un manual se pueden encontrar los detalles de servicio técnico Meyer Sound en caso de que las soluciones propuestas no hayan funcionado. Actualmente gozan de éxito manuales de instrucciones en forma de animaciones interesantes o vídeo manuales que llegan al usuario mucho mejor que en forma de un folleto. Este tipo de manual ayuda a que el usuario vea el vídeo entero sin saltarse las especificaciones y las descripciones técnicas complicadas de Meyer Sound M3D-SUB, como se suele hacer teniendo una versión en papel.

¿Por qué vale la pena leer los manuales de instrucciones?

Sobre todo es en ellos donde encontraremos las respuestas acerca de la construcción, las posibilidades del dispositivo Meyer Sound M3D-SUB, el uso de determinados accesorios y una serie de informaciones que permiten aprovechar completamente sus funciones y comodidades.

Tras una compra exitosa de un equipo o un dispositivo, vale la pena dedicar un momento para familiarizarse con cada parte del manual Meyer Sound M3D-SUB. Actualmente se preparan y traducen con dedicación, para que no solo sean comprensibles para los usuarios, sino que también cumplan su función básica de información y ayuda.

    x 1 INTRODUCTION The M3D and M3D-Sub QuickFly rigging system is a complete integrated solution for transporting and ying M3D and M3D-Sub loudspeakers. This system includes everything below the motors, to the caster rails and covers that carry and protect the system in transport. All the hardwar e for rigging the system remains captive to the lou[...]

    2 3 Using a three- or four -high M3D block will make each block heavier (see T able 1) and less stable, so the blocks will requir e extra care when rolling over an uneven surface and up truck ramps. Conversely , larger blocks will make more efcient use of a truck’ s car go space and make a more efcient load-in and strike. The optional M3D t[...]

    2 3 TIP: Meyer Sound’ s optional transit covers will protect M3Ds stacked for transport. They are easy to use, because one side opens with V elcro seams, allowing two stagehands to easily put on the cover without having to lift it over the top of the block. W e suggest you strap each block, once loaded, with a car go strap to prevent rubbing thr [...]

    4 5 When choosing your rigging point capacities, always keep in mind that the entire weight of the array may shift completely to either the front or back points. Thr ee factors contribute to variations in the center of gravity: 1. The curvature of the array 2. The tilt of the entire array inclusive of the MTG-3D T op Grid 3. The number and types of[...]

    6 7 LIFTING MECHANISMS The number and lift capacity of chain motors used to lift the array are dependent on the array’ s combined weight, including the weight of any underhung clusters, and its orientation and splay . For a smaller array , it may be sufcient to use 1-ton motors, but for lar ger arrays, 2-ton motors may be necessary . The lift [...]
