A good user manual
The rules should oblige the seller to give the purchaser an operating instrucion of Orange Micro 4GS, 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 Orange Micro 4GS 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 Orange Micro 4GS. 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 Orange Micro 4GS should contain:
- informations concerning technical data of Orange Micro 4GS
- name of the manufacturer and a year of construction of the Orange Micro 4GS item
- rules of operation, control and maintenance of the Orange Micro 4GS 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 Orange Micro 4GS 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 Orange Micro 4GS, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Orange Micro 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 Orange Micro 4GS.
Why one should read the manuals?
It is mostly in the manuals where we will find the details concerning construction and possibility of the Orange Micro 4GS 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.

automatically when the RamPak 4GS is properly installed in your Apple. Your computer knows to look for available memory every time you turn it on, so the RamPak's expansion benefits are immediately realized. Memory management is up to you. It is accomplished through use of the RamPak system utilities, which may be implemented at any time once [...]

3. Touch the power supply of the Apple IIGS before handling the RamPak 4GS. Static charges may damage your RAM or other delicate electronic parts. 4. If you have purchased additional RAM for the Ram Pak, this must be installed before the RamPak is installed in your Apple. Turn ahead to ‘Installing RAM Chips in the RamPak 4GS on page 5, follow the[...]

development which require large amounts of memory to load and run. For these situations, the RamPak 4GS provides expansion capability to 4Mb. Your RamPak 4GS has been specifically designed for use with 256K x 4 DRAM chips. This allows you to expand at a rate of 2 chips (or 256K) at a time, as opposed to the 8 chip minimum expansion required by othe[...]

Other times, no effort is even put forth to understand caching, since the idea of altering the way your system handles memory really doesn’t sound too “safe” anyway.
