Abstract
A sound-volume display unit for use in an audio system has a key for controlling the sound volume, a display device, and a display control device. When the key is not operated, the display control device displays information other than the sound volume on the display device. When the key is operated and when the level of the sound volume corresponding to the key operation is not minimum, the display control device displays the corresponding level of the sound volume on the display device for a predetermined duration. After a lapse of the predetermined duration, the display control device causes the display device to return to the display state used before the level of the sound volume was displayed. On the other hand, when the key is operated and when the level of the sound volume corresponding to the key operation is minimum, the display control device displays the corresponding level of the sound volume on the display device and also maintains the display state even after a lapse of the predetermined duration.
