Un bon manuel d’utilisation
Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation American Dryer Corp. MDG75V. Le manque du manuel d’utilisation ou les informations incorrectes fournies au consommateur sont à la base d'une plainte pour non-conformité du dispositif avec le contrat. Conformément à la loi, l’inclusion du manuel d’utilisation sous une forme autre que le papier est autorisée, ce qui est souvent utilisé récemment, en incluant la forme graphique ou électronique du manuel American Dryer Corp. MDG75V ou les vidéos d'instruction pour les utilisateurs. 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 American Dryer Corp. MDG75V 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.
Malheureusement, peu d'utilisateurs prennent le temps de lire le manuel d’utilisation, et un bon manuel permet non seulement d’apprendre à connaître un certain nombre de fonctionnalités supplémentaires du dispositif acheté, mais aussi éviter la majorité des défaillances.
Donc, ce qui devrait contenir le manuel parfait?
Tout d'abord, le manuel d’utilisation American Dryer Corp. MDG75V devrait contenir:
- informations sur les caractéristiques techniques du dispositif American Dryer Corp. MDG75V
- nom du fabricant et année de fabrication American Dryer Corp. MDG75V
- instructions d'utilisation, de réglage et d’entretien de l'équipement American Dryer Corp. MDG75V
- signes de sécurité et attestations confirmant la conformité avec les normes pertinentes
Pourquoi nous ne lisons pas les manuels d’utilisation?
Habituellement, cela est dû au manque de temps et de certitude quant à la fonctionnalité spécifique de l'équipement acheté. Malheureusement, la connexion et le démarrage American Dryer Corp. MDG75V ne suffisent pas. Le manuel d’utilisation contient un certain nombre de lignes directrices concernant les fonctionnalités spécifiques, la sécurité, les méthodes d'entretien (même les moyens qui doivent être utilisés), les défauts possibles American Dryer Corp. MDG75V et les moyens de résoudre des problèmes communs lors de l'utilisation. Enfin, le manuel contient les coordonnées du service American Dryer Corp. en l'absence de l'efficacité des solutions proposées. Actuellement, les manuels d’utilisation sous la forme d'animations intéressantes et de vidéos pédagogiques qui sont meilleurs que la brochure, sont très populaires. Ce type de manuel permet à l'utilisateur de voir toute la vidéo d'instruction sans sauter les spécifications et les descriptions techniques compliquées American Dryer Corp. MDG75V, comme c’est le cas pour la version papier.
Pourquoi lire le manuel d’utilisation?
