摘要： In a radio selective call receiver, the sensitivity of a radio receiver is set to a lower sensitivity level which is lower than a normal sensitivity level of the radio receiver. In the lower sensitivity level, a plurality of predetermined channels are searched for a receiving channel while receiving a radio signal. Therefore, a receiving channel with higher signal level can be selected. When no receiving channel is found in the lower sensitivity, the channel search is performed in the normal sensitivity.

摘要： A radio selective paging receiver includes a reception unit, a control unit, and a timepiece unit. The reception unit is controlled to start transmission in synchronism with at least a standard time, receives a radio signal modulated by a selective paging signal containing time information in transmission information, and demodulates the radio signal. The control unit controls operation of the reception unit, determines call reception and time information in accordance with the demodulated signal, and processes the call reception and the time information. The timepiece unit at least temporarily holds the obtained time. In setting the time information obtained by operating the reception unit to the timepiece unit, the control unit adjusts the time with a predetermined time lag such that a carry to the minute or hour unit is not generated at a predetermined timing self data is received.

摘要： A radio apparatus judges whether the electric field intensity of a radio signal detected by a level detector is high by a comparator. The radio apparatus detects a synchronizing signal for making synchronization with the radio apparatus from the radio signal by a synchronizing signal detector. Moreover, the radio apparatus detects the bit rate of an information stop signal in a system using a POCSAG signal of a radio selective-calling receiver from the radio signal by a stop signal detector. When the electric field intensity of the radio signal is high, the synchronizing signal is not detected, and the bit rate of the information stop signal is not detected, the radio apparatus decides by a decision circuit that cross modulation occurs in the radio signal and attenuates the radio signal by turning on an attenuator.

摘要： In a radio selective call receiver, a reception channel is efficiently selected from a plurality of radio channels without unnecessary channel switch. When having lost synchronism with a first radio channel, the radio channels are scanned in a predetermined sequential order to search for a second radio channel with which synchronization is established. When the second radio channel has been found, it is again determined whether synchronization can be established with the first radio channel. When synchronization has been established with the first radio channel, the first radio channel is selected as the reception channel. When synchronization fails to be established with the first radio channel, the second radio channel is selected as the reception channel.

摘要： A pager which does not delete or rewrite received messages can be produced at such a low cost that it is viable as a disposable pager. Messages are stored sequentially as they are received, packed in memory end-to-end, so that memory efficiency is maximized. No complex memory management is required, minimizing production costs. If memory is full or near-full when a new message is received, either the message is displayed and not stored, or receipt of the new message is refused. By using removable, nonvolatile memory modules, the pager unit can be reused, while enabling old messages to be externally archived for indefinite periods of time.

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.
