A processor is configured to control a first communication module and a second communication module by executing a control program stored in a memory module such that communication at a first frequency included in a first frequency band or a second frequency included in a second frequency band is carried out using the first communication module, and such that communication at a third frequency included in a third frequency band is carried out using the second communication module. The first communication module includes an adjustment module. The adjustment module is configured to reduce interference between the first antenna and the second antenna when the communication at the third frequency is carried out.
