摘要
In a selectively called radio receiver operable with battery saving and including a memory (21) for predetermined bit rates and predetermined formats (synchronizing signals, each accompanied by at least one identification code specific to the receiver) in correspondence to the bit rates a received radio signal of a good received state is demodulated into a demodulated signal including at least one selective call signal and having an input bit rate, which is judged as an adjudged bit rate if identical with one of the predetermined bit rates with an error allowed. Provided that the demodulated signal has at least one of the predetermined formats that corresponds to the adjudged bit rate and provided that the selective call signal includes the identification code according to the at least one of predetermined formats, a message signal is produced from the demodulated signal. Preferably, the receiver includes a control unit (17) comprising an information processing unit (19) controlling a bit rate judging circuit (23), a synchronizing signal detector (25), an identification code detector (27), and a message memory (29), all supplied with the demodulated signal.
