摘要：
The invention provides a cell phone which shows good receiving sensitivity even in a state where synchronization with a base station is not provided, such as power-on and detection of a dead space.The invention alternately switches between a plurality of antennas a predetermined number of times per fixed time predetermined in accordance with the number of perch channels in a state where synchronization with a base station is not provided, and sets an antenna whose mean value of the receiving level of each of these antennas is the highest as an antenna to be used subsequently, that is, an antenna to open a control channel.
