Adjusting the volume
When the button is pressed, the status LED lights up to match the current volume.
Each time a volume button is pressed, the status LEDs blink and the number of LEDs that are blinking increases or decreases according to the volume that is set.
The status LEDs blink three times when the maximum or minimum volume is reached.
When the power is turned on, the unit starts with the volume level that was set before being placed on standby. However, if the volume was previously set to high, it starts with the volume setting lowered to a certain level.
