The Freestyle Libre 3 Signal Loss is a great device, but like all electronics, it sometimes has its issues. If your Freestyle Libre 3 Signal Loss is not working, take a look at this troubleshooting guide.
We’ve collected answers to the most frequent reasons you’ll see Freestyle Libre 3 Signal Loss not working and explained them in plain language for easy troubleshooting.
Quick Fix
To troubleshoot a Freestyle Libre 3 signal loss, check the sensor placement and Bluetooth connection, restart your phone, move closer to the sensor, disable interference-causing devices, and reinstall the app if needed.
Understanding Signal Loss Alarms
When your FreeStyle Libre 3 system triggers a Signal Loss Alarm, it’s essential to understand what’s happening.
This alarm is triggered when the sensor is too far away from your smartphone (over 33 feet), Bluetooth is turned off, or there’s an error or problem with the sensor. The system automatically detects and reports signal loss, and the alarm will occur if the sensor and reader are out of range for 20 minutes.
The FreeStyle Libre 3 system provides continuous glucose monitoring and automatically detects signal loss, providing an alarm if the reader and sensor are out of range.
This means you’ll be alerted if there’s an issue with the connection. To restore the connection, simply move back within range (within 33 feet, unobstructed) and wait 2-4 minutes. Your system will automatically reconnect, and you’ll be able to continue monitoring your glucose levels with confidence.
Troubleshooting Common Issues
If you’re experiencing issues with your FreeStyle Libre 3 system, don’t worry – troubleshooting common problems is often a straightforward process.
- Check your distance: If you’re getting a Signal Loss Alarm, make sure you’re within 33 feet of your smartphone.
Move closer and wait 2-4 minutes to allow the system to automatically reconnect.
- Enable alarms: Verify alarms, including the low glucose alarm, are turned on in the app settings.
This will confirm you receive notifications when you need them.
- Device compatibility: Check that your smartphone is compatible with the FreeStyle Libre 3 app and operating system to avoid connectivity issues.
- Bluetooth settings: Certify Bluetooth is turned on and functioning correctly on your phone.
Try restarting your phone or toggling Bluetooth off and on to resolve connectivity issues.
- Sensor communication: If you’re experiencing issues with your FreeStyle Libre 3 sensor, try restarting the app or turning Bluetooth off then on to restore communication.
Resolving Reader and Sensor Problems
You’ve checked your distance, enabled alarms, and verified device compatibility, but you’re still experiencing issues with your FreeStyle Libre 3 system.
Now, it’s time to focus on resolving Reader and sensor problems. If your Reader’s battery is running low, charge it to prevent signal loss alarms and reading issues.
Make sure the Reader is within its operating temperature range of 10°C to 45°C to prevent power-on issues. Also, remember to turn on the Reader before applying the sensor to prevent issues with sample application.
Check the Reader’s battery level regularly and replace the batteries if necessary.
Certify the sensor is properly applied to your skin, free of dirt, oil, hair, or sweat, to prevent skin irritation and reading issues.
If you’re using mobile devices, guarantee they’re compatible with the FreeStyle Libre 3 system and running on compatible operating systems.
