Get To Know Your Smart Transmitter

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.

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.

Being Smart About Using Your Smart Transmitter

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.
