Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Crown Pulse 21100. 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 Crown Pulse 21100 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 Crown Pulse 21100 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 Crown Pulse 21100 devrait contenir:
- informations sur les caractéristiques techniques du dispositif Crown Pulse 21100
- nom du fabricant et année de fabrication Crown Pulse 21100
- instructions d'utilisation, de réglage et d’entretien de l'équipement Crown Pulse 21100
- 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 Crown Pulse 21100 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 Crown Pulse 21100 et les moyens de résoudre des problèmes communs lors de l'utilisation. Enfin, le manuel contient les coordonnées du service Crown 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 Crown Pulse 21100, 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 Crown Pulse 21100, 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 Crown Pulse 21100. 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.

    5 2.0 Mechanical Installation A vertical rack space of 2U (88mm high) is required, with an in rack depth of 18.1 inches (460mm). The amplifier protrudes 1.6 inches (40mm) from the rack supports. If the unit is likely to undergo extreme vibration through trucking and touring, front rack ear reinforcement brackets and rear mounting plates must be fit[...]

The rack framework must also be connected to the same grounding circuit. The unit must NOT be operated unless the power cables' ground wire is properly terminated - this is important for personal safety a[...]

    7 Inputs For each channel, there is a 1/4” phone jack socket, male & female XLR and pluggable removable terminal block connectors provided for signal input on the rear panel of the amplifier . Each is electronically balanced at an impedance greater than 10k ohms. The removable terminal block, phone jack and both XLR connectors are internally [...]

    8 Outputs Both binding post and Speakon ® connectors are provided for each channel, these are internally wired in parallel so either or both may be used. Note that it is possible to lever the caps out of the ends of the binding posts to insert 4mm banana type plugs but this will invalidate the product safety approvals in some territories. The side[...]

    11 Indicators... F . Clip This light is in fact rather more sophisticated than a simple clip indicator; it actually measures distortion. This may occur either due to clipping, trying to drive too low an impedance speaker load or any other mechanism that causes the output of the amplifier channel to not be as expected by the monitoring circuit. Note[...]
