ABSTRACT:
A radio telephone system having a charger separated from a base unit and connectable to a radio telephone to provide power thereto, and a recording and reproducing circuit separated from the radio telephone and the base unit to record and reproduce a voice signal. The voice signal representing a telephone call from the subscriber line is transmitted from the base unit via the charger to the recording and reproducing circuit for the voice signal to be recorded therein. The recorded voice signal can be reproduced and played through a speaker in places detached from the base unit. The radio telephone system includes a mode selector to set the system either in an automatic answering mode or a reproduction mode. Even when the battery power of the radio telephone runs out, the recording and reproducing circuit can still reproduce the recorded voice signal where an alternating current power outlet is available for the charger to provide power to the recording and reproducing circuit.
