How should I respond to the G7 Signal Loss alert?
App Troubleshooting tips: (It will take up to 5 minutes for any of these to work.)
- Turn Bluetooth off. Then turn it back on and leave it on.
- Keep your display device within 6 meters of the sensor with nothing between them, including your body, walls, and water.
- Keep your display device on the same side of your body as your sensor. Bluetooth works best when the sensor and display device are in sight of each other.

- Restart your phone and the app.
To help prevent signal loss:
- Use recommended phone settings listed in the app at Profile > Phone Settings
- Keep your phone battery charged to at least 20%
- If Signal Loss continues for more than 30 minutes, contact technical support (in the app, go to Profile > Contact)
Receiver Troubleshooting tips: (It will take up to 5 minutes for any of these to work.)
- Keep the receiver within 6 meters of your sensor with nothing between them, including your body, walls, and water.
- Keep your receiver on the same side of your body as the sensor so they are in sight of each other.
- Press a receiver button to wake it up and start a new connection attempt.
If Signal Loss continues for more than 30 minutes, contact technical support.
