Abstract
In a pager, one of a plurality of kinds of baud rates is automatically selected for each of the service areas or network providers. With this provision, the conventional operation to produce pagers for the respective transmission speeds becomes unnecessary, which resultantly improves productivity as well as operability and usability thereof. The pager includes an antenna, a radio section, a demodulating section, a low-pass filter, a comparator, a decoder, a CPU, a notifying section, a ROM, a RAM, and a switching circuit. Receiving a broadcast radio wave, the pager produces a demodulated signal therefrom. In accordance with the demodulated signal, the pager automatically sets operation of the decoder to either one of a plurality of transmission speeds of the received signal and conducts a paging operation when a paging number of the received signal matches a paging number beforehand stored therein.
