In a cellular telephone, a music data transfer control unit and a remote
control unit control a close-range radio communications unit to establish
a remote control session and a data transfer session, between the music
data transfer control unit, remote control unit and an audio device, and
transfer audio data to the audio device. If the data transfer session is
not established during predetermined periods (W1+W2) after the
establishment of the remote control session, a control unit disconnects
the remote control session.
