A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Kramer Electronics VS-1211, 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?

Why don't we read the manuals?

An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of Kramer Electronics VS-1211, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Kramer Electronics service.
