plugged in, the LED will flash blue. It will turn off
once the internal battery is fully charged.
Charging Another Device (Power Bank)
Open the watertight sealed door, and simply
plug in your own USB cable into the full size
USB port. The charging LEDs on the front will
display the battery remaining level of the internal
battery. Once power from the internal battery is
depleted, it will stop charging your external
device and the charging LEDs will turn off.
NOTE: As not to rapidly decrease the battery
level of your CBT20, it is best to use the Power
Bank function when you are not actively playing
any music from your speaker.
Factory Reset
If you are experiencing connectivity issues, you
may need to perform a hard reset on your
CBT20. To do so, power your speaker off then
on. Once powered on, press and hold the
play/pause button for 6 seconds and it will reset
the Bluetooth connection. Once reset
successfully, the LED indicator will flash red and
blue for a new pairing.
Preserving the Waterproof Seal
Ensure that the side compartment door is fully
pushed in. This will prevent any dust and
moisture from entering the USB and AUX ports.
