ULT FIELD 1

Unable to turn on the speaker or the speaker suddenly turns off

The rechargeable built-in battery may be empty or running low. Connect the speaker to an AC outlet with a USB AC

adaptor (commercially available) for battery charging.

Depending on the type or specifications of the USB AC adaptor, if you use the speaker at a loud volume, the

remaining power of the rechargeable built-in battery may decrease or the speaker may turn off even while the

speaker is connected to an AC outlet by the USB AC adaptor. This, however, does not indicate a malfunction. If such

a case occurs, turn off the speaker and let the battery fully charge itself before you use the speaker.

The Auto Standby function may have been activated. Turn off the Auto Standby function.
