Use a factory reset if your Polk Signa S1 or S2 behaves unusually or does not respond to the buttons. All settings on the soundbar are erased, so you will need to set them again.

1. Turn the soundbar on.
2. Press and hold the POWER, SOURCE and VOL + buttons on top of the soundbar together for at least 5 seconds.
3. The LEDs light up or blink three times to show the reset has happened.
4. Wait 6 seconds, then turn the soundbar on again.

If the subwoofer no longer plays after a reset, see "Polk Signa S1 and S2: Subwoofer won't connect".

If the problem continues, please contact the store where you bought the soundbar, or lodge a service request with us.
