Claims

[Scope of utility model registration request]

a display element that displays the operation of the radio receiver; and a determination circuit that determines whether the radio receiver is in an operating state;
The invention is characterized by comprising a control circuit that switches the brightness level of the display element based on the output of the discrimination circuit, so that when the radio receiver is in an inactive state, the display element emits light at a lower brightness than when it is in operation. display device.
