A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of QSC Audio 522AA, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.

What is an instruction?

The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of QSC Audio 522AA one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities. An instruction is a compilation of information about an item/a service, it is a clue.

Unfortunately, only a few customers devote their time to read an instruction of QSC Audio 522AA. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.

What should a perfect user manual contain?

First and foremost, an user manual of QSC Audio 522AA should contain:
- informations concerning technical data of QSC Audio 522AA
- name of the manufacturer and a year of construction of the QSC Audio 522AA item
- rules of operation, control and maintenance of the QSC Audio 522AA item
- safety signs and mark certificates which confirm compatibility with appropriate standards

Why don't we read the manuals?

Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of QSC Audio 522AA alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of QSC Audio 522AA, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the QSC Audio service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of QSC Audio 522AA.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the QSC Audio 522AA item, and its use of respective accessory, as well as information concerning all the functions and facilities.

After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.

    5 Introduction - Networking the RA VE 522aa The RA VE 522aa has two RJ-45 network connection ports on the r ear panel. One port is labeled "QSControl" and supports standard 10BASE-T Ethernet. The other port is labeled "CobraNet" and supports 100BASE-TX, also k nown as "Fas t Ethernet". In the followi ng sections, we de[...]

    6 Third, the RA VE 522aa and QSControl.net system are targeted at network switch deployments. The consumer costs of Ethernet switches have continued to fall over the last several years and are now comparable with repeaters on a per port basis. In addit ion, the sophistication and scalability of network switches make them i deal for new installation[...]

    7 Example #2 - CobraNet X-over mode: This is the simplest connection you can make between the RA VE 522aa and any of the other RAVE/BASI S models. Y ou use a CA T -5 crossover cable connected between the CobraNet ports of each unit. No network switch is required. This connection allo ws audio to pass between the two RA VE/BASIS units over CobraNet.[...]
