Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Furuno CSH-7. 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 Furuno CSH-7 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 Furuno CSH-7 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 Furuno CSH-7 devrait contenir:
- informations sur les caractéristiques techniques du dispositif Furuno CSH-7
- nom du fabricant et année de fabrication Furuno CSH-7
- instructions d'utilisation, de réglage et d’entretien de l'équipement Furuno CSH-7
- 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 Furuno CSH-7 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 Furuno CSH-7 et les moyens de résoudre des problèmes communs lors de l'utilisation. Enfin, le manuel contient les coordonnées du service Furuno 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 Furuno CSH-7, comme c’est le cas pour la version papier.

Pourquoi lire le manuel d’utilisation?

Tout d'abord, il contient la réponse sur la structure, les possibilités du dispositif Furuno CSH-7, l'utilisation de divers accessoires et une gamme d'informations pour profiter pleinement de toutes les fonctionnalités et commodités.

Après un achat réussi de l’équipement/dispositif, prenez un moment pour vous familiariser avec toutes les parties du manuel d'utilisation Furuno CSH-7. À l'heure actuelle, ils sont soigneusement préparés et traduits pour qu'ils soient non seulement compréhensibles pour les utilisateurs, mais pour qu’ils remplissent leur fonction de base de l'information et d’aide.

    1-4 Seabed echo and tilt angle Case 1: T ilt angle 30 to 40 degrees This tilt angle will display the entire seabed since it is captured by the full width of the beam. Case 2: T ilt angle 10 to 20 degrees This tilt angle will only display half the seabed since it is only captured by the lower half of the beam. Case 3: T ilt angle 0 to 10 degrees Thi[...]

    1-5 Points to consider • Normally , a vertically distributed fish school is a better sonar tar get than the seabed, because it reflects the transmitted pulse back toward the transducer . • In case 3, both fish schools a and b are presented. Gener- ally speaking, however , midwater fish schools tend to be larger than bottom fish schools and they[...]
