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.
Le radiotéléphone portatif réalise le balayage des canaux pour un des deux systèmes de canaux "A" ou "B" découlant de la division d'une bande de service cellulaire pour obtenir deux canaux ayant le plus grand RSSI. Le processeur principal détermine lequel des deux canaux reçoit les données, afin de syntoniser le téléphone sur le canal qui reçoit les données et se mettre en veille. Le processeur principal arrête le fonctionnement durant la détection du signal de synchronisation de mot, économisant de ce fait l'énergie de la pile.
