Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Alesis BRC. 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 Alesis BRC 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 Alesis BRC 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 Alesis BRC devrait contenir:
- informations sur les caractéristiques techniques du dispositif Alesis BRC
- nom du fabricant et année de fabrication Alesis BRC
- instructions d'utilisation, de réglage et d’entretien de l'équipement Alesis BRC
- 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 Alesis BRC 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 Alesis BRC et les moyens de résoudre des problèmes communs lors de l'utilisation. Enfin, le manuel contient les coordonnées du service Alesis 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 Alesis BRC, 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 Alesis BRC, 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 Alesis BRC. 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 CHAPTER 1: INTRODUCTION 1.0 ABOUT THE BRC Congratulations! You’ve just purchased an incredible tool that will assist in streamlining your recording projects. The BRC master remote control is the key element that makes the most of the ADAT digital recording system. Whether using it in a professional commercial studio, recording a live performanc[...]

  • Page 6

    2 • Modular recording. This is the feature that makes ADAT and the ADAT/BRC system perhaps the most flexible multitrack recorder ever designed. Because ADAT’s S-VHS tape format is so inexpensive, you can easily afford to record alternate versions of vocals, solos, background accompaniments; whatever your creative urge requires. Modular recordin[...]

  • Page 7

    3 • Digital interface and sample rate converter option. If you need to integrate your ADAT recordings to digital recording equipment from other manufacturers, an optional accessory box, the Alesis AI-1, can isolate the digital audio signal of two tracks at a time from any single eight-track ADAT in the system, and assign the pair to the industry [...]

    4 1.1 IMPORTANT NOTES ABOUT THIS MANUAL This manual has been divided into two separate books, of which this is the first. This book is designed as a reference to assist the recording professional in learning the basic operation of the BRC. All functions are explained in a clear manner, using step-by-step instructions and illustrations for setting u[...]

    5 The BRC can control as many as 16 ADATs for up to 128 tracks. The track select section of the BRC provides access to 32 tracks at any time. Four buttons let you switch between TRACK 1–32, TRACK 33–64, TRACK 65–96 and TRACK 97–128. The button that has its LED lit will indicate which group of tracks is currently selected, as will the LEDs c[...]

    6 For more information on Auto-Punch and related controls, see section 4.3. 1.2E Rehearsing This works just like a real recording, but instead lets you “audition” exactly how a punch is going to work. By pressing the REHEARSE button, you can test out and change the settings of the various recording functions to get the results you want without [...]

    7 TAPES Analog audio recorders typically move tape past the heads at anywhere from 1-7/8 to 30 inches per second. Higher speeds result in a higher bandwidth , or ability to record high-frequency signals. ADAT’s digital audio signals require much higher bandwidth than analog audio. In addition to moving the tape faster to handle the increased band[...]

    13 CHAPTER 2: HOOKUP 2.0 POWER The BRC works with any AC voltage from 90 to 250 volts, 50 to 60 Hz. This eliminates the need for transformers or voltage switches. The BRC comes with a line cord for the destination to which the BRC is shipped. The BRC’s IEC-spec AC cord (do not substitute any other AC cord) is designed to feed an outlet that inclu[...]
