Abstract

PROBLEM TO BE SOLVED: To provide a mobile telephone set in which current consumption is reduced by lighting only the back lights of a specific key part and an LCD part being a block consisting of mainly used keys when using the Internet connection service using a radio terminal. SOLUTION: In the mobile telephone set which controls lighting and extinguishing the back lights of respective parts based on key input, a part where the back light is lighted is divided into an LCD part 101, a specific key part 102 and a speech key part 103 to be separately controlled. When the specific key 102 is depressed, only the LCD part 101 and the specific key 102 are lighted. When the speech key part 103 is depressed, all of the LCD part 101, the specific key 102 and the speech key 103 are lighted.
