ABSTRACT:
In a cellular telephone set for monitoring a control channel, an EEPROM memorizes both a home SID number and a sub-home SID number. A radio section seeks four radio channels within a radio frequency band under control of a CPU and successively receives radio signals through the radio channels to produce a sequence of received data signals. The CPU detects an operational SID number from each of the received data signals to compare the operational SID number with the home SID number and to further compare the operational SID number with the sub-home SID number only when the operational SID number does not coincide with the home SID number. The CPU selects, as a selected channel, one of the radio channels based on a result of the comparison and makes the radio section tune the selected chancel to monitor the selected channel as the control channel.
