another speaker, and then test whether this channel still
does not work;
• If only Bluetooth, U-Disk, or AUX mode does not work,
change the audio source, change the audio cable and test
again, and make sure that all the cables are completely
pushed into the device.
6. U-Disk cannot be played?
• Please try other different U-Disk playback tests.
• Make sure that the U-Disk capacity does not exceed 32GB
and can work normally.
• Make sure that the BL20A is in the U-Disk play mode.
7. U-Disk play rustling?
• Song format problem. WAV contains DTS multi-channel, the
BL20A supports stereo but does not support multi-channel,
you can convert DTS to stereo. Download the Foobar2000
software on the computer to convert the audio channel.
8. Can’t power on?
• Long press the power switch button to power on/off.
• Make sure that the LED light on the power adapter stays on.
• If it does not light up: Unplug the power adapter from the
BL20A, plug the power adapter directly into the AC power
source, and see if the LED will light up. If it still does not light
up, it may be a problem with the power adapter. Please
contact us to replace the power adapter.
• You can use the DC12-24V power adapter of the camera or
router to connect the BL20A to test whether the BL20A can
be turned on.
