Smart Transmitter
Find out how the Eversense E3 Smart Transmitter is designed to work the way you need and to be worn the way you want.
Eversense E3 is the only CGM with a removable smart transmitter that provides on-body vibe alerts. This gives you the freedom to take the transmitter on and off* when you need a break.
You can remove the smart transmitter from the upper arm at any time, except during calibration. Remember that no glucose data are collected when the smart transmitter is not communicating with the sensor.
When the smart transmitter and mobile device are not within range of each other, any data gathered by the smart transmitter is stored and sent to the app when the mobile device and smart transmitter are back within range.
Adhesive patches are provided in both white and clear material. The white adhesives are perforated, allowing for moisture to be wicked away. The clear adhesives allow for use on occasions when you may want more discretion.
When you place the smart transmitter back on the sensor site, it can take up to 10 minutes for the sensor communication to re-start and for glucose readings to appear in the app.
If you plan to undergo an MRI procedure, the sensor can stay in place under the skin, but the smart transmitter must be removed and left outside the room. Certain conditions must be met for the MRI testing. For MRI Safety Informat...
You can submerge the smart transmitter in water that’s up to 1 meter (3.2 feet) deep for a maximum of 30 minutes. You can take showers and swim without extra protection.
In the Troubleshooting, Connection with Smart Transmitter subsection of your Eversense E3 User Guide, you will find a list of Frequently Asked Questions (FAQs) on pairing and connecting your smart transmitter to your mobile device. If your connection issues do not resolve after following these instructions, please call Customer Service at 1-844-736-7348 (844-SENSE4U).
To get a Good or Excellent signal in the Placement Guide, try slightly rotating the smart transmitter over the sensor. Wait about 1 second for the Placement Guide to refresh between each adjustment. If helpful, tap Show More Detail to display a numerical value of signal strength.
To ensure you receive continuous glucose readings and other information, wear your smart transmitter all the time, except when charging it. You can remove it anytime you want, but if you remove it during a calibration, you will be prompted to calibrate again. If you do not wear your smart transmitter for longer than 24 hours while in the 2 Daily Calibrations Phase or longer than 40 hours while in the 1 Daily Calibration Phase, you will force the system to re-enter the Initialization Phase.

The Eversense® E3 Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels for up to 180 days in persons with diabetes age 18 and older. The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are still required for calibration primarily one time a day after day 21, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense E3 CGM System is a prescription device; patients should talk to their health care provider to learn more. For safety information click here.
