6. Troubleshooting
If you encounter issues with your ELECDER D19 earbuds, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Earbuds not pairing with device. | Bluetooth is off on device; earbuds not in pairing mode; previously paired device interfering. | Ensure Bluetooth is enabled. Place earbuds back in case, then take them out to re-enter pairing mode. Forget "Elecder D19" from your device's Bluetooth list and re-pair. |
| Only one earbud working. | Earbuds not paired with each other; low battery on one earbud. | Place both earbuds back into the charging case, close the lid, wait a few seconds, then open and take them out again. Ensure both earbuds are charged. |
| No sound or low volume. | Device volume too low; ear tips not properly sealed; debris in earbud nozzle. | Increase volume on your device. Adjust earbud position or try different sized ear tips for a better seal. Clean earbud nozzles. |
| Charging case not charging. | Faulty cable/charger; improper placement on wireless charger. | Try a different USB cable and power adapter. Ensure the case is correctly aligned on the wireless charging pad. |
| Bluetooth connection unstable. | Interference; distance from device; low earbud battery. | Reduce distance between earbuds and device. Avoid environments with strong Wi-Fi or other Bluetooth signals. Ensure earbuds are fully charged. |
