A "Signal Loss" alert from the BUZUD CGM system means that your display device* has temporarily stopped receiving glucose readings from the sensor due to a connection issue.

The Signal Loss alert appears on both the BUZUD CGM app and receiver as follows:

• Signal Loss alert in the app
• Signal Loss alert on the receiver

Common Causes of Signal Loss:

• The distance between the display device and the BUZUD CGM transmitter is too far
• Phone settings may be preventing the app from running properly in the background or maintaining Bluetooth connection

Troubleshooting Steps:

1. Ensure your smart device or receiver* is within 6 meters (20 feet) of the BUZUD CGM transmitter with no major obstacles in between.
2. Make sure you are using a phone listed on BUZUD’s compatible devices list.
3. Verify that your phone settings follow the recommended BUZUD iPhone or Android settings.
4. Have the following information ready:
   • Your BUZUD CGM app login credentials
   • The Transmitter ID currently in use

How to Re-Pair the Transmitter:

1. Open the BUZUD CGM app and remove the currently paired CGM device.
2. Go to your phone’s Bluetooth settings, locate the BUZUD CGM device, and select Unpair.

These steps should help resolve most signal loss issues.

If the Problem Persists:

• Contact BUZUD Technical Support for further assistance.
• Use your Blood Glucose Meter (BGM) to make treatment decisions during this period.
• Refer to the BUZUD CGM User Guide for more details on the Signal Loss alert, other notifications, and recommended device settings.

* Display devices are sold separately. For a list of compatible smart devices, please visit the BUZUD official website. The optional receiver can be purchased through authorized BUZUD channels.
