PROBLEM TO BE SOLVED: To provide a radio communication device including a two-dimensional display device, such as a touch panel liquid crystal display device, and enables rough and fine tuning of an operation frequency with a simple predetermined operation, such as touching a screen of the device with a finger.SOLUTION: A radio communication device specifies the position in a first direction (lateral direction) and the position in a second direction (vertical direction) and the direction and amount of movement of a predetermined operation on a screen of a two-dimensional display device, determines a direction to change an operation frequency according to the direction of movement of the predetermined operation in the first direction, determines the number of tuning steps to change the operation frequency according to the position of the predetermined operation in the second direction, and determines the amount of change of the operation frequency on the basis of the amount of movement of the predetermined operation in the first direction and the number of tuning steps.SELECTED DRAWING: Figure 10 |
