Abstract

PURPOSE:To easily know ON-state of a power supply, by transmitting a power supply confirmation signal from the base station after a prescribed time in case no answer is obtained. CONSTITUTION:When the control circuit 9 receives a call signal via the talking line 12, the circuit 9 transmits the selective call signal 22. In case the travelling object telephone device 1 receives the signal 22 and does not set the radio transmitter 4 under a transmission mode, the signal 23 showing no answer received is transmitted through said line 12. Then the power supply confirmation signal 24 is transmitted in a prescribed time of Tsec since a transmission of the signal 22. In response to this, whether the confirmation answer signal 25 is received or not is stored in the storage device 11. After this, in case the call signal 26 is received again within a prescribed time, the circuit 9 examines the contents of the device 11 when no answer is given to the selective call signal 27 from the device 1. Then the result of the above-mentioned examination is informed to the originator by driving automatic announcing device 10 and by the voice signal 28 through the circuit 12.
