The video / audio equipment according to this embodiment has an on-timer function and an off-timer function. The microcomputer 10 has a flash memory 13. In the areas E1, E2, and E3 of the flash memory 13, a volume set value for an on-timer, a volume set value for an off-timer, and a volume set value for normal power-on are stored, respectively.
[0013]
The initial values of these volume setting values are set, for example, as follows.
[0014]
Volume setting value for on-timer = 10
Volume setting value for off timer = 2
Volume setting value for normal power-on = 6
[0015]
The volume setting value indicates that the larger the number, the higher the volume.
[0016]
When the power of the video / audio device is turned on by the on-timer function, the microcomputer 10 adjusts the volume at power-on to a volume corresponding to the volume set value for the on-timer stored in the area E1 of the flash memory 13. I do. When the off-timer setting is performed, the microcomputer 10 adjusts the volume immediately after the off-timer setting to a volume corresponding to the off-timer volume setting value stored in the area E2 of the flash memory 13. Further, when the power of the video / audio device is turned on by means other than the on-timer function, the microcomputer 10 sets the volume at power-on to the volume set value for normal power-on stored in the area E3 of the flash memory 13.
