Troubleshooting
1. What should I do if the speaker can not pair with the Bluetooth
device and play music accordingly?
(1) Please check the specification/ the manual of the Bluetooth device
(your mobile or computer), and check if the device can support the
A2DP stereo audio transmission. If yes, please turn on the A2DP
stereo mode.
(2) Ensure the speaker at the Bluetooth status, if there are many
bluetooth devices around you, it may be hard to scan, then please
turn off other devices.
2. What should I do if the Micro SD card /USB flash disk can not
work?
(1) Ensure that the Micro SD card/USB flash disk is in good condition.
Also check that the audio files are the correct formats - MP3/WMA/
WAV/APE/FLAC.
(2) Besides the above case, the problem maybe the compatibility of
the Micro SD card/USB flash disk.
We recommend you formatting the Micro SD Card to FAT32 file
formats.
3.What should I do if the speaker get stuck and all the button can
not working?
The speaker's inner system may be wrong with some inappropriate
operation. Please try using a needle on the reset hole next to the
charging port.
