Icons on the pump screen indicate when insulin dosing is increasing, decreasing, or being stopped by the system.

Is the Tandem t:slim insulin pump waterproof?

Tandem pumps are watertight, tested to a depth of three feet for up to 30 minutes. In the event of accidental submersion, your pump is safe. It is not recommend to shower, bathe, or swim with your Tandem pump.

*Dexcom CGM sold separately. Transmitter can only be paired with one medical device (either a Dexcom receiver or t:slim X2 insulin pump) and one consumer device (phone or tablet) at the same time.

* You cannot dismiss alerts and alarms from the app and must do so on the pump itself, but once an alert or alarm has been dismissed on the pump it will also disappear from the mobile app.

*The information on the t:connect mobile app display may not be identical to the current status of your pump. Wireless uploads from the t:connect mobile app to the cloud-based t:connect web application require a compatible phone and an internet or wireless data connection. Uploads to the t:connect web application do not take place in real time and should not be relied upon by healthcare providers or caregivers for remote patient monitoring. Standard carrier data rates may apply.

* CGM sold separately.

† If glucose values are predicted to be above 180 mg/dL, Control-IQ technology calculates a correction bolus using the Personal Profile settings and a target of 110 mg/dL and delivers 60% of that value.

‡ Bolus delivery from the t:connect mobile app requires a compatible smartphone model and operating system, an app update, a remote software update on the t:slim X2 insulin pump and additional training. Only available to customers who reside in the United States.
