Why Yamaha NS-SW200 Subwoofer does not enter standby mode automatically?

If your Yamaha subwoofer does not enter standby mode automatically, noise from external appliances might be activating it. Move the subwoofer away from such appliances and/or reposition the connected speaker cables. Also, set the AUTO STANDBY switch to the HIGH or LOW position.
