In this case, if the devices are the same, a specific signal is transmitted during a call, and it can be determined whether or not the devices are the same based on the presence or absence of the signal.

If the communication partner device is the same device, that is, if it has the same function as the present device (step S12)
Yes), the CPU 13 keeps the wireless communication control unit 12
A call process is executed through (step S13). Thereafter, when the user ends the call by hanging up the telephone or the like (Yes in step S14), the CPU 13 ends the processing here.

On the other hand, if the communication partner device is not the same device, that is, if it is a normal telephone (No in step S12), the CPU 13 stores information indicating the current operation state (for example, display state) in the RAM 15 operation state. Storage area 15b
(Step S15), the display unit 17 is controlled to turn off the display, and the CPU 13 itself shifts to the suspend mode (step S16). In the suspend mode (also referred to as sleep mode), all functions including the wireless communication function including the display are stopped.

In this state, the CPU 13 executes a call process through the wireless communication control unit 12 (step S17).
Thereafter, when the user ends the telephone call by hanging up (Yes in step S20), the CPU 13 shifts to the operation mode based on the operation state information held in the operation state storage area 15b, and the operation state of the apparatus is changed. Is restored to the state before the transition to the suspend mode (step S21).
