12.What can be done if the UTWS3 cannot be powered on/charged with an unresponsive indicator light?
1. Try other charging cables, and use an 1-2A adapter to charge it for 1 to 2 hours.
2. Leave it aside for half of a day.
3. Clear pairing (Keep the ear hooks inside, and then long-press the multifunction button of the charging case for 12s after opening the case lid.)
4. Use alcohol wipes to clean the four charging contacts detailedly, and put UTWS3 back to the charging box when the contacts are dried. If the indicator light is not on still, please repeat 2-4 for a few times.
5. If the above measures cannot help that the UTWS3 still cannot be searched for by mobile phones, it is suggested to ask for after-sale service.
