PURPOSE:To detect the wear state of a battery by sending a data relating to the battery status of a wireless equipment while including a transmission code sent to a main body side and displaying the data on the main body. CONSTITUTION:In closing a switch 3 in a remote controller 1 being a wireless equipment, the power of a battery 2 operates a control section 4 to start the internal timer. The control section 4 reads the internal timer value and sends its accumulated time to a transmission section 6 together with a predetermined code and the transmission section 6 sends it to a main body 7. The main body 7 discriminates whether or not a code included in the received data is coincident with the determined code by a control section 9, and drives a load 11 depending on the contact of the code in the case of coincidence. Then whether or not the accumulated time included in the received data is within the predetermined time is discriminated and when the time is exceeded, information representing the bad state of the battery 2 is displayed on a display section 10.
