The rules should oblige the seller to give the purchaser an operating instrucion of Delta Electronics LCP-1250, 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.

- rules of operation, control and maintenance of the Delta Electronics LCP-1250 item
- safety signs and mark certificates which confirm compatibility with appropriate standards

Why don't we read the manuals?

Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of Delta Electronics LCP-1250 alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of Delta Electronics LCP-1250, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Delta Electronics service.
