A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of ADTRAN SLC-5 U-BR1TE III, 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 ADTRAN SLC-5 U-BR1TE III 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.

Unfortunately, only a few customers devote their time to read an instruction of ADTRAN SLC-5 U-BR1TE III. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.

What should a perfect user manual contain?

First and foremost, an user manual of ADTRAN SLC-5 U-BR1TE III should contain:
- informations concerning technical data of ADTRAN SLC-5 U-BR1TE III
- name of the manufacturer and a year of construction of the ADTRAN SLC-5 U-BR1TE III item
- rules of operation, control and maintenance of the ADTRAN SLC-5 U-BR1TE III 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 ADTRAN SLC-5 U-BR1TE III 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 ADTRAN SLC-5 U-BR1TE III, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the ADTRAN 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 ADTRAN SLC-5 U-BR1TE III.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the ADTRAN SLC-5 U-BR1TE III item, and its use of respective accessory, as well as information concerning all the functions and facilities.

After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.
