Abstract

PURPOSE:To use the unit as normal telephone set normally and to enable to inform quickly and surely the occurrence of failure in case of emergency, by poviding the emergency signal production section generating the emergency signal and the identification signal for possessor. CONSTITUTION:The reception section 10 performs reception and reproduction. Further, the carrier of the oscillator 13 is modulated at the modulator 32 at the signal from the microphone 37 and the amplifier 36, and it is transmitted from the antenna 35 via the frequency multiplication 33 and the amplifier 34. On emergency, the emergency button 44 is operated. Thus, the switch 43 is closed and the emergency signal produced at the emergency oscillator 41 and the signal of possessor's number from the possessor's identification signal generator are fed to the modulator 32. The signals are received at the base station and the occurrence of emergency in its service area is informed and it is automatically connected to the specific parts.
