Abstract
An automatically switching circuit for the receiving sensitivity in a cordless telephone comprises a base unit and a portable handset in wireless communication with the base unit, which is responsive to the flow of charging current from the base unit to the portable handset for reducing the gain of an antenna or amplifying stage to a desired low level, thereby preventing erroneous ringing due to surrounding noise signals or disturbances while the portable handset rests on the base unit.
