A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Omega Speaker Systems OS550 Series, 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 Omega Speaker Systems OS550 Series 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 Omega Speaker Systems OS550 Series. 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 Omega Speaker Systems OS550 Series should contain:
- informations concerning technical data of Omega Speaker Systems OS550 Series
- name of the manufacturer and a year of construction of the Omega Speaker Systems OS550 Series item
- rules of operation, control and maintenance of the Omega Speaker Systems OS550 Series 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 Omega Speaker Systems OS550 Series 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 Omega Speaker Systems OS550 Series, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Omega Speaker Systems 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 Omega Speaker Systems OS550 Series.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the Omega Speaker Systems OS550 Series 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.

    Thermal Radiation Heat is transferred from all objects via radiation in the form of electromagnetic waves or by conduction or convection. All objects having a temperature greater than absolute zero (-273°C, -459°F, 0 K) radiate energy. The thermal energy radiated by an object increases as the object gets hotter. Measurement of this thermal energy[...]

    In Appendix A, we showed how emissivity is an important parameter in calculating the temperature of an object via infrared means. In this section we discuss how to determine a specific emissivity value. If you know the material of the object, use Table B-1 in Appendix B to look up its approximate emissivity. Most organic materials such as plastics,[...]

    Appendix: Determining an Unknown Emissivity C C-2 Method 3 1. Use this method to measure objects at temperatures below 500°F (260°C). 2. Place a large piece of masking tape on the object (or at least a sample of the object material). Allow time for the masking tape to reach the object temperature. 3. Set the emissivity of the thermometer to 0.95.[...]

    C-3 Appendix: Determining an Unknown Emissivity C Method 4 1. Paint a sample of the object material with flat black lacquer paint. 2. Set the emissivity to 0.97 and measure and record the temperature of the painted portion of the sample material - Area “ A ” in Figure C-1. Make sure that the painted area of object material fills the FOV of the [...]
