A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Electro-Voice CPS 4, 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?

- rules of operation, control and maintenance of the Electro-Voice CPS 4 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 Electro-Voice CPS 4 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 Electro-Voice CPS 4, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Electro-Voice 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 Electro-Voice CPS 4.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the Electro-Voice CPS 4 item, and its use of respective accessory, as well as information concerning all the functions and facilities.
