Abstract: A synthesizer varies the receive frequency band so that a receiver can receive signals in the receive frequency band of the uplink incoming call channel of a portable telephone. A receiver demodulates, from a receive signal entered via an antenna, the incoming call response signal of a portable telephone connected by radio to a base station. A comparator detects, from the incoming call response signal, the portable telephone's own ID number or telephone number stored in a memory. The memory consists of an EEPROM. An alerting section, in response to the detection of the portable telephone's own ID number or telephone number, performs call operation. The alerting section is provided with a loudspeaker for emitting an alerting sound, an LED for intermittently emitting light and a vibrator for generating vibration. A call operation select button selects the setting or resetting of the loudspeaker, the LED and the vibrator. The call operation stop button stops call operation.
