Abstract
A mobile communication terminal in accordance with the present invention includes a first wireless communication unitcorresponding to a first wireless communication system, an interfacedetachably connecting an external apparatus, a determination unitfor determining whether or not the external apparatusconnected to the interfacecorresponds to a second wireless communication system and is a second wireless communication unitconsuming less power than the first wireless communication unit, a battery voltage detection unitfor detecting battery voltage of a power supply unitcontaining a battery and a control unitfor controlling the first wireless communication unitto be in a disabled state when the first wireless communication unitis communicating and the battery voltage detected by the battery voltage detection unitis equal to or less than the predetermined value in the case where connection of the second wireless communication unitis determined by the determination unit. Thus multimode communication depending on the battery voltage can be executed efficiently without causing unexpected circumstances to the user.
