References and Important Risk Information

Basal-IQ technology is not a substitute for active self-management of your diabetes. Please see back cover for more information.

* If your glucose alerts and readings do not match your symptoms or expectations perform a fingerprick to confirm your blood glucose level.

1.Additional feature updates are not currently available for the t:slim X2 Pump with Dexcom G5 Mobile CGM integration and are subject to future regulatory approvals. Charges may apply.

2.Tested up to 1 metre for 30 minutes (IPX7 rating).

*CGM-based treatment requires fingerpricks for calibration; may result in hypoglycaemia if calibration is not performed, when taking paracetamol, or if symptoms/expectations do not match CGM readings. If symptoms persist, please contact your healthcare professional.
†The Dexcom G5 Mobile CGM transmitter can only be paired with one medical device (either a Dexcom receiver or t:slim X2 Insulin Pump) and one compatible mobile device (phone or tablet) at the same time.

This application is for demonstration purposes only and is not identical to the functionality of the t:slim X2 Insulin Pump. It should not be used for therapy decisions. To see which smart devices are compatible with the t:simulator App, please refer to the app’s full listing on The App Store and Google Play.
