A good user manual
The rules should oblige the seller to give the purchaser an operating instrucion of Cisco VWIC3-4MFT-T1/E1, 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.
