A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of ADTRAN 239 T1 HDSL4, 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.
