A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Juniper Juniper MX-series MX960, 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 Juniper Juniper MX-series MX960 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.

- rules of operation, control and maintenance of the Juniper Juniper MX-series MX960 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 Juniper Juniper MX-series MX960 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 Juniper Juniper MX-series MX960, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Juniper service. Lately animated manuals and instructional videos are quite popular among customers.
