A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Rogue Audio Hera, 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?

Eventually, when one still can't find the answer to his problems, he will be directed to the Rogue Audio service. Lately animated manuals and instructional videos are quite popular among customers.
