Abstract
This selectively called receiver intermittently receives a frame signal including call information and transmitted through radio communication from a calling end on a battery saving basis and checks the presence of a call to the receiver. When the call to the receiver is detected, the receiver generates a ringing tone such as a bell sound. While a conventional selectively called receiver usually sets a reference level for proper binarization and reproduction of the frame signal and generates a ringing tone related to battery checking simultaneously, the inventive receiver performs the setting of the reference level and the generation of a ringing tone related to battery checking with different timings in order to stabilize the setting of the reference level.
