Abstract: A switch enables a first circuit and a second circuit to be connected to an antenna and a port. A first detecting unit detects whether the external apparatus is connected to the port and detect the type of the external apparatus connected to the port. A second detecting unit detects whether the first circuit or the second circuit is activated. A control section controls the switch, when the first detecting unit detects that the external apparatus is not connected to the port or when the detected type of the external apparatus is inadaptable for the circuit to be activated, the circuit to be activated is connected to the antenna and that, when the detected type of the external apparatus is adaptable for the circuit to be activated, the circuit to be activated is connected to the port.
