Abstract

According to one embodiment, an electronic device includes wireless communication modules, a storage module, a communication module, a frequency specifying module, and a controller. The wireless communication modules use different communication frequency bands. The storage module stores operation frequencies to control display of a display module and setting information. Each of the operation frequencies is associated with a piece of the setting information to control the display of the display module based on the operation frequency. The communication module specifying module specifies a wireless communication module that is performing communication. The frequency specifying module specifies, from the operation frequencies stored in the storage module, an operation frequency no integer multiple of which is included in the communication frequency band of the specified wireless communication module. The controller controls the display of the display module based on a piece of the setting information associated with the specified operation frequency.

Claims

1. An electronic device comprising:

a plurality of wireless communication modules configured to use different communication frequency bands;
