CHARGING
Charge the battery before first use and at least once every two

recommend that you charge the speaker for about 10 minutes
prior to use, if it has been unused for at least 7 days.
1. Plug one end of the included Micro USB Charging Cable
into the Micro USB Charging Port on the speaker, then
plug the other end into a USB power source, such as a
wall charger, power bank, computer, etc. (available
separately). The LED Indicator will illuminate solid red,
indicating that charging is in progress.
2. When charging is complete, the LED Indicator will turn
off.

Bluetooth pairing mode.
If the speaker is already paired to a device and that
device is powered on and within range, the speaker will
attempt to reconnect to the paired device. If it cannot
automatically reconnect to the paired device, you can
either double press the Power Button to reconnect the
device or proceed with pairing a different device.
