- Navigate to Settings > Apps > HearLink 2.
- Check the permissions to ensure it has access to necessary settings, specifically the Phone permissions. If it’s not allowed, make it "Allowed" - learn more.

4. Unpair and Repair:
- In your phone’s Bluetooth settings, unpair the hearing aids (Forget the device).
- Ensure that the hearing aids are turned off.
- Turn on both the phone and hearing aids, then initiate the pairing process again through the HearLink app or Bluetooth settings.

5. Check for Multiple Devices:
- If you have multiple Bluetooth devices paired, this might cause disconnection issues. Consider unpairing devices that you don’t use actively - learn more.

6. Update Firmware:
- Make sure that both your phone and the HearLink 2 app are updated to the latest version, as updates can often fix connectivity problems.

7. Check Battery Levels:
- Ensure that your hearing aids have sufficient battery life, as low battery can lead to connectivity issues.
