Step-by-Step Guide: How to Update t:slim X2 Software

Follow these steps to update your t:slim X2 insulin pump software seamlessly:

Step 1: Complete Preliminary Steps on Tandem Source

1. Log in to Tandem Source: Visit the Tandem Source platform on tandemdiabetes.com and log in with your account.
2. Check Eligibility: Confirm your pump is eligible for the update. Some updates, like Control-IQ, require a prescription or online training.
3. Request Update ID: Follow prompts to receive your unique Update ID number. This may take a few days if a prescription is needed.
4. Complete Training: If required (e.g., for Control-IQ), finish the online training module to ensure safe use of new features.

Step 2: Prepare Your Computer and Pump

1. Download Tandem Device Updater:
   Go to tandemdiabetes.com/support and download the TDU for your PC or Mac.
   Install the software, ensuring you have administrator rights.
2. Stop Insulin Delivery:
   Detach your infusion set and remove the cartridge from your t:slim X2 pump.
   Ensure that no insulin is being delivered during the update.
3. Connect Your Pump:
   Plug the micro USB cable into your pump and computer.

Warning: Do not disconnect the pump during the update, as this could render it inoperable.

Step 3: Run the Software Update

1. Open Tandem Device Updater:
   Launch the TDU on your computer and log in with your Tandem Source credentials.
2. Enter Update ID:
   Input the unique Update ID number provided by Tandem.
3. Follow On-Screen Prompts:
   The TDU will guide you through the update process, which typically takes 15–30 minutes, depending on your internet speed.
   If prompted, reboot your pump by tapping “YES” or the blue tick icon on the pump screen.
4. Verify Update Completion:
   Once complete, your pump will display an “Update Successful” message.
   Navigate to Options > My Pump > Pump Info to confirm the new software version.

Step 4: Post-Update Checks

1. Confirm Settings:
   Verify your profiles, date, time, and other settings. Incorrect settings can lead to over- or under-delivery of insulin.
   Consult your healthcare provider if adjustments are needed.
2. Resume CGM Session:
   If you use a CGM, restart your sensor session by tapping START SENSOR on the My CGM screen.
3. Load a New Cartridge:
   Unlock your pump, tap START, and load a fresh cartridge to resume insulin therapy.
4. Monitor Insulin on Board (IOB):
   After an update, IOB resets to zero. Wait until prior IOB is depleted (consult your doctor for timing) before relying on bolus calculations to avoid hypoglycemia.
