power indicator lights green.)

2 Change the AUTO STANDBY setting.
- LOW: Normally select this position to activate this function.
- HIGH: If this function does not operate with AUTO STANDBY switch set to LOW, select this position so that the
subwoofer detects input signals with a lower level and switches the power on automatically.
- OFF: Select this position to deactivate this function, for example, when the subwoofer switches the power on
unexpectedly by sensing noises from other appliances.
Notes:
• This function does not operate when the POWER switch is set to the OFF position, or when you manually set the
subwoofer to standby mode by pressing the STANDBY/ON button.
• Noise received from other appliances may extend the time period before the subwoofer places itself in standby mode to
more than 8 minutes.
