Abstract
The portable radio telephone performs the channel scanning for one of the two channel systems 'A' and 'B' divided from a cellular service band to select two channels with largest RSSIs. The main processor determines which one of the two channels receives the data, so as to tune the telephone to the channel that receives the data, and stands by. The main processor stops the operation during detecting word synchronization signal, thus saving the battery power.
