Basal-IQ Software Update for tslim X2 Insulin Pump

Tandem carefully develops software updates to ensure your safety and satisfaction. Please review the instructions and take time to understand the new features before beginning your update.

What's Included

This software update will add Basal-IQ™ technology to your pump, which helps reduce the frequency and duration of low-glucose events by predicting sensor glucose levels 30 minutes ahead and suspending insulin if they are expected to drop below 4.4 mmol/L. Insulin resumes as soon as sensor glucose values begin to rise.

Update Your Pump

Here are the three simple steps to update the software on your t:slim insulin pump:

Before You Begin

Please consult the Tandem Device Updater User Guide and have the following on hand:

A backup insulin delivery option, such as a syringe and long-acting insulin, in case there are any issues updating your pump. Your blood glucose (BG) meter so that you can check your BG prior to starting the update. Supplies to change your cartridge. We recommend performing the update when you are ready for a new cartridge.
A convenient time to stop all insulin delivery, detach your infusion set, and remove your cartridge. This update will take 15 to 30 minutes.
A compatible computer with an internet connection (wired ethernet is preferred).
And remember, the t:flex® insulin pump and t:slim G4™ insulin pump are not currently compatible with the Tandem Device Updater.

Responsible Use of
Basal-IQ Technology

Systems like the t:slim X2 insulin pump with Basal-IQ technology are not substitutes for active diabetes management, as there are common scenarios in which automated systems cannot prevent hypoglycemia. The Basal-IQ feature relies on continuous CGM readings and will not be able to predict glucose levels and suspend insulin delivery if your CGM is not working properly or is unable to communicate with your pump. Be sure to always use your pump, cartridges, CGM, and infusion sets as instructed and check them regularly to make sure they are working properly. Always pay attention to your symptoms, actively monitor your glucose levels, and treat according to your healthcare provider’s recommendations.

Important Safety Information

The t:slim X2 insulin pump with Basal-IQ technology (the System) consists of the t:slim X2 insulin pump, which contains Basal-IQ technology, and a compatible continuous glucose monitor (CGM, sold separately). The t:slim X2 insulin pump is intended for the subcutaneous delivery of insulin, at set and variable rates, for the management of diabetes mellitus in people requiring insulin. The t:slim X2 insulin pump can be used solely for continuous insulin delivery and as part of the System. When used with a compatible CGM, the System can be used to suspend insulin delivery based on CGM sensor readings. The pump and the System are indicated for use in individuals six years of age and greater. The pump and the System are intended for single user use. The pump and the System are indicated for use with NovoRapid or Humalog U-100 insulin. The System is not indicated for use in pregnant women, people on dialysis, or critically ill users. Users of the pump and the System must: be willing and able to use the insulin pump, CGM, and all other system components in accordance with their respective instructions for use; test blood glucose levels as recommended by their healthcare provider; demonstrate adequate carb-counting skills; maintain sufficient diabetes self-care skills; see healthcare provider(s) regularly; and have adequate vision and/or hearing to recognize all functions of the pump, including alerts. The t:slim X2 pump and the CGM transmitter and sensor must be removed before MRI, CT, or diathermy treatment. Visit tandemdiabetes.com/safetyinfo for additional important safety information.
