Using the RESET button

If the speaker cannot be turned on or cannot be operated despite it being turned on, open the cap on the rear side and push the RESET button with a pin or other pointed objects. The speaker is reset and turns off.

After pushing the RESET button, turn on the speaker. If it does not turn on, consult your nearest Sony dealer.


  • The speaker cannot be reset while the power is off.
  • Pairing information is not deleted by pushing the RESET button. This is different from the speaker initialization.
  • To reset the speaker while it is being powered by the built-in battery, push and hold the RESET button until the (power) indicator turns off.
  • After resetting, the volume, function, and EXTRA BASS settings may be different.
