Hitherto, a demonstration for the purpose of making a product noticeable has sometimes been performed at a shop or the like for the purpose of sales promotion or the like.
Conventionally, in order to make a product perform a demonstration not performed in an ordinary use such as a specific display, a specific audio output or the like, an ON/OFF operation of the demonstration was switched by operating patterns thereof according to a specific operation or being connected to a specific component used for the demonstration.
However, in a case of selecting whether or not the demonstration is started, since the specific operation or the specific component was required, there occurred the following problem: it was required to memorize an operation method of the specific operation, and the work of performing the operation was difficult.
SUMMARY OF THE INVENTION
An object of the present invention is to improve a data communication apparatus in order to provide a data communication apparatus capable of eliminating the above-mentioned problems.
Another object of the present invention is to provide a data communication apparatus which can automatically start a demonstration operation.
Still another object of the present invention is to make a data communication apparatus which is used by connecting to a telephone line perform a demonstration easily without a complex operation and not perform the demonstration when it is not required.
