5. Maintenance
5.1 Cleaning
To maintain optimal performance and hygiene:
- Regularly wipe the earbuds and charging case with a soft, dry, lint-free cloth.
- Do not use abrasive cleaners, alcohol, or chemical solvents.
- Gently clean the earbud mesh and charging contacts with a dry cotton swab if necessary.
5.2 Storage
When not in use, always store the earbuds in their charging case. This protects them from dust, scratches, and potential damage, and keeps them charged for your next use.
6. Troubleshooting
If you encounter any issues with your Celly ZED1WH Zed1 earbuds, please refer to the following common solutions:
- Earbuds not charging: Ensure the charging cable is securely connected to both the case and the power source. Verify the charging contacts on the earbuds and inside the case are clean and free of debris.
- Earbuds not pairing: Make sure Bluetooth is enabled on your device. Place the earbuds back into the case, close it, then open it again and remove them to re-enter pairing mode. If issues persist, try forgetting "ZED1WH" from your device's Bluetooth list and re-pairing.
- Only one earbud working: Place both earbuds back into the charging case, close the lid for a few seconds, then open it and remove them simultaneously. This often re-syncs them. Ensure both earbuds are sufficiently charged.
- Poor sound quality or disconnections: Ensure your device is within the 10-meter Bluetooth range and there are no significant obstacles between the earbuds and your device. Avoid environments with strong electromagnetic interference.
- Controls not responding: Ensure the earbuds are charged and connected. Try restarting your connected device.
If these steps do not resolve the issue, please contact Celly customer support for further assistance.
