Abstract: A cordless telephone is described comprising a fixed part which includes a reception section for receiving exact reception channel frequencies lying in a predetermined frequency range at equal intervals apart and a transmission section for transmitting exact transmission channel frequencies lying at a predetermined duplex interval from the reception channel frequencies. The cordless telephone further comprises a mobile part which includes a reception section for receiving frequencies lying in the range of the transmission channel frequencies of the fixed part and a transmission part for transmitting frequencies lying in the range of the reception channel frequencies of the fixed part. The mobile part includes a frequency control loop which using the transmission channel frequency transmitted by the fixed part as reference frequency holds its reception section fixedly tuned to the received transmission channel frequency.
