Troubleshooting
If the TX-139 fails to link to your mobile device or if it fails to play
music after being connected, the user shall check if your mobile
device supports A2DP. If you cannot connect the TX-139 to your
phone, do as follows:
● Ensure that the speaker is in on-state. Ensure that the
Bluetooth feature is activated on your phone. ● Check that the
speaker is within 10m of your phone and that there are no
obstructions between the speaker and the phone, such as walls
or other electronic devices. ● The TX-139 powers off or does not
turn on again could be a problem with the power supply. ● If the
speaker has problems to play sound files from USB, please
check the correct formatting of the sources. They should be
formatted in exFAT / NTFS. ● The maximum supported data
storage is 64GB. The USB port doesn’t support any external hard
disk drive (HDD).
