The doorbell is powered by a rechargeable battery. When the battery level is low, the app will typically notify you. Recharge the doorbell using the provided USB cable. For optimal battery life, avoid extreme temperatures.
6.3 Software Updates
Ensure your doorbell's firmware and the companion app are kept up-to-date. Check the app regularly for available updates, which often include performance improvements and security enhancements.
7. Troubleshooting
- No Power/Not Turning On:
Ensure the doorbell is fully charged. Connect it to the charging cable and allow it to charge for several hours.
- Cannot Connect to WiFi:
Verify that your WiFi network is 2.4 GHz. The doorbell does not support 5 GHz networks. Ensure the doorbell is within range of your WiFi router. Restart your router and try the pairing process again.

Check your phone's app notification settings to ensure notifications for the doorbell app are enabled. Also, verify that the app is running in the background or has necessary permissions.

Ensure the camera lens is clean. Check your WiFi signal strength at the doorbell's location; a weak signal can affect video streaming quality. Move the router closer or consider a WiFi extender.
- Two-Way Audio Not Working:
Check the microphone and speaker settings within the app. Ensure your phone's volume is up. There might be a slight delay in audio transmission due to network conditions.
- Indoor Chime Not Ringing:
Ensure the indoor speaker is powered on and properly paired with the doorbell. Refer to the chime's specific instructions for re-pairing if necessary.
