A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Kramer Electronics SG-6, 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.

Eventually, when one still can't find the answer to his problems, he will be directed to the Kramer Electronics service.
