CHARGING
We recommend that you fully charge the speaker before using it for the first time to
maximize battery life. It takes approximately 2-3 hours to fully charge. An acoustic signal will
indicate a low battery. To charge the loudspeaker battery, connect the supplied micro USB
cable to the charging port (6) and connect it to any charging adapter (5V voltage and at least
1A output current) or to a USB in a PC. The charging progress is signalled by a flashing LED
below the button (1); when the battery is fully charged, the LED will stay lit. During charging,
the loudspeaker can be used for calls and music playback.
