SOLUTION : When a received radio wave of a portable telephone is demodulated by an RF module 6, a portable telephone number contained in a demodulated signal is determined identical to a number preset in a flash ROM 9, the received radio wave is determined to have been received for a predetermined period, and determined to be in a reproduced state, a voice mute circuit 16 performs a mute operation, and the muting of an output voice is executed.
