Why does my Yamaha NS-SW500 Subwoofer turn on unexpectedly?

If your Yamaha Subwoofer turns on unexpectedly, it might be due to noise from nearby appliances activating it. Try moving the subwoofer away from these appliances or repositioning the connected speaker cables. If the AUTO STANDBY switch is set to HIGH, try setting it to LOW. As another option, you can set the AUTO STANDBY switch to the OFF position.
