发明名称 Radio selective call receiver in which message non-reception period is managed
摘要 A radio selective call receiver includes a receiving section, a recognizing section, an alarm section and a control section. The receiving section receives a radio signal. The recognizing section detects a message and a selective call number from the received radio signal, and recognizes selectively a reception time of the message as a latest reception time based on a kind of the selective call number. The alarm section generates an alarm in response to an alarm instruction. The control section compares at a comparison timing, a time difference between a current time and the latest reception time and a predetermined time period, and selectively outputs the alarm instruction to the alarm section based on the comparing result.
