Abstract: A small electronic apparatus such as an electronic organizer, electronic memo, etc. is disclosed which has a memory for storing data, and a communication unit for transmitting data stored in the memory to another electronic apparatus, and for receiving data from the other electronic apparatus. The apparatus selects, before transmitting at least one portion of said data, either of an add mode (transmitted data is added to data stored in the other electronic apparatus) and a update mode (data stored in the other electronic apparatus is replaced with the transmitted data). The apparatus has a signal unit for, when the add mode is selected, transmitting a first signal indicative that the add mode is selected to the other electronic apparatus, and for, when the update mode is selected, transmitting a second signal indicative that the update mode is selected to the other electronic apparatus. The apparatus displays data which has been transmitted when a data transmission error has occurred.

Abstract: Dial data inputted from a keyboard are registered in an internal memory. When the desired dial data are retrieved from the registered dial data and a dial key is pressed, the retrieved dial data are converted to corresponding dial tone signals and supplied to a speaker. Thus, the speaker outputs corresponding dial tones. At this time, a portable automatic dialing unit is acoustically coupled to the mouthpiece of a telephone set. Thus, the dial tones outputted from the speaker are again converted to the dial tone signals by the telephone set and transmitted to a telephone line, thereby driving a telephone switchboard. If the dial data include key code data "P", production of the dial tone signals is interrupted for a prescribed period. If the dial data include key code data "P-P", on the other hand, production of the dial tone signals is interrupted until the dial key is pressed again.
