Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Mackie M1400/M1400i. 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 Mackie M1400/M1400i 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 Mackie M1400/M1400i 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 Mackie M1400/M1400i devrait contenir:
- informations sur les caractéristiques techniques du dispositif Mackie M1400/M1400i
- nom du fabricant et année de fabrication Mackie M1400/M1400i
- instructions d'utilisation, de réglage et d’entretien de l'équipement Mackie M1400/M1400i
- 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 Mackie M1400/M1400i 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 Mackie M1400/M1400i et les moyens de résoudre des problèmes communs lors de l'utilisation. Enfin, le manuel contient les coordonnées du service Mackie 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 Mackie M1400/M1400i, 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 Mackie M1400/M1400i, 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 Mackie M1400/M1400i. 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.

Such a condition causes the M•1400/M•1400i to engage its PROTECT mode (when a signal is present), muting all signals at the amp?[...]

    15 If you shut down your system, turn off your ampli- fiers first. When powering up, turn on your amplifiers last. This way , equipment feeding the amp won’t “pop” or “thud” when it’s powered up or down. POWER CORD W e all know what a power cord is. The M•1400/M•1400i has a big beefy cord built in.

    20 The AMP MODE switch determines the in- put signal routing within the M•1400/M•1400i amplifier . Shipped from the factory , the switch is set to STEREO . This is correct for about 90% of the applications using an amp like this (hence the TYPICAL indicator near it). But you may be in the 10% bracket, requiring spe- cial input routing within th[...]

    21 simply stops. This causes a sine wave to “square off,” and the average power going into the speaker is roughly double that of a sine wave. Square waves sound awful, and could possibly damage your speakers and/or your reputation. The LIMITER is especially handy when you’re working with loud output levels. Having the signal spikes (kick drum[...]

    23 GENERAL PRECAUTIONS AND CONSIDERA TIONS AC POWER CONSIDERA TIONS Be sure the M•1400/M•1400i is plugged into an outlet that is able to supply the correct volt- age specified for your model. If the line voltage should drop below about 97% of the rated voltage, the M•1400/M•1400i will no longer be able to supply rated power . (It will conti[...]

    24 The extension cord used to supply power to the “amp rack” should have a third wire safety ground to avoid presenting a safety hazard.

Power amplifiers can have momentary peak current [...]
