A good user manual
The rules should oblige the seller to give the purchaser an operating instrucion of Fine Digital AW-250, 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 Fine Digital AW-250 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.

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