Unable to turn on the speaker or charge the built-in battery
- Fully charge the built-in battery.
- Make sure the USB AC adaptor is connected to the speaker and the AC outlet firmly.
- Push the RESET button on the bottom of the speaker with a pointed object, such as a pin.
To turn on the speaker after resetting, press and hold the (power)/ PAIRING button for three seconds, or connect the speaker to an AC outlet with the supplied micro-USB cable and USB AC adaptor. After about two seconds, the speaker is turned on automatically, and enters in the start-up mode. If the speaker does not enter the start-up mode, consult your nearest Sony dealer.
