What should a perfect user manual contain?

First and foremost, an user manual of American Power Conversion MX28B200 should contain:
- informations concerning technical data of American Power Conversion MX28B200
- name of the manufacturer and a year of construction of the American Power Conversion MX28B200 item
- rules of operation, control and maintenance of the American Power Conversion MX28B200 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 American Power Conversion MX28B200 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 American Power Conversion MX28B200, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the American Power Conversion service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of American Power Conversion MX28B200.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the American Power Conversion MX28B200 item, and its use of respective accessory, as well as information concerning all the functions and facilities.
