Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Crestron electronic CEN-WAP-ABG-1G.

La condition est son caractère lisible et compréhensible.

Qu'est ce que le manuel d’utilisation?

Le mot vient du latin "Instructio", à savoir organiser. Ainsi, le manuel d’utilisation Crestron electronic CEN-WAP-ABG-1G décrit les étapes de la procédure. Le but du manuel d’utilisation est d’instruire, de faciliter le démarrage, l'utilisation de l'équipement ou l'exécution des actions spécifiques. Le manuel d’utilisation est une collection d'informations sur l'objet/service, une indice.

- instructions d'utilisation, de réglage et d’entretien de l'équipement Crestron electronic CEN-WAP-ABG-1G
- signes de sécurité et attestations confirmant la conformité avec les normes pertinentes

Enfin, le manuel contient les coordonnées du service Crestron electronic en l'absence de l'efficacité des solutions proposées.

Ce type de manuel permet à l'utilisateur de voir toute la vidéo d'instruction sans sauter les spécifications et les descriptions techniques compliquées Crestron electronic CEN-WAP-ABG-1G, comme c’est le cas pour la version papier.

Pourquoi lire le manuel d’utilisation?
