Tandem Device Updater with ID Number

You will need an Update ID Number from Tandem Diabetes Care in order to update your pump. If you don’t yet have an Update ID Number, please go to this web page for more information.

Follow these steps to update your pump once you have your Update ID Number:

  1. Before you begin
    • Choose a convenient time to stop all insulin delivery, detach your infusion set, and remove your cartridge. This update will take approximately 15 to 30 minutes.
    • Make a note of your insulin on board (IOB). After the update your IOB and max hourly bolus will be reset to zero, so you will need to keep this in mind when making insulin therapy decisions for the next several hours.
    • Have your unique Update ID Number ready, which you should receive by email once we have received your prescription (if required) and you've completed your online training. (This number expires in 60 days from email receipt.) 
    • Make sure your pump serial number matches with the serial number provided in the email.
    • Have supplies to load a new cartridge. We recommend performing the update when you are ready for a new cartridge. Otherwise, you will need at least 80 units of insulin remaining in your existing cartridge before performing the update.
    • Start or restart a continuous glucose monitoring (CGM) sensor session after updating. You do not need to wait until your sensor session has ended.
    • Use a computer with an internet connection. A wired ethernet connection is preferred.
    • Have a backup insulin delivery option available, such as a syringe and long-acting insulin in case there are any issues updating your pump
    • Have a blood glucose meter so that you can check your blood glucose prior to starting the update
  1. Install the Tandem Device Updater

  1. Update your device 

The Tandem Device Updater should automatically start after you install it on your computer. Follow the prompts to update your t:slim X2 insulin pump. The process should take fewer than 10 minutes to complete.

When updating your t:slim X2 pump software, always follow all security precautions and instructions provided to you in the user guide for the Tandem Device Updater

You will see an error message on your computer screen if the Updater encounters a condition that will not allow you to continue. Follow the on-screen instructions to resolve the error and continue with your update.

If you have trouble connecting your pump or starting an update, consult the Troubleshooting section of the Tandem Device Updater User Guide.

  1. After a successful update
    • Your pump settings won’t be erased during the update process. Check your settings to confirm.
    • You will need to start or restart your CGM sensor session after updating. You do not need to wait until your sensor session has ended. If you had an active CGM session when you started the update process, you can start your current session again on your pump once the update is complete. The update process will not stop the session.

    • You may see a pump screen stating that your CGM Session has been stopped after your pump comes back on. Despite this message, you may restart your current sensor session once the update is complete.
    • Tap Options, My CGM, Start Sensor. When prompted to enter a Sensor Code, tap Skip. After a few minutes, your pump will reconnect to your existing sensor session and your CGM readings will appear.
    • Your IOB and max hourly bolus have been reset
    • Load a cartridge and resume insulin. If your current cartridge has more than 80 units, you can use an existing cartridge. Always disconnect tubing from the site on your body before going through the load sequence.
    • If you are using Control-IQ technology, confirm that your Control-IQ technology setting is on

Optional

    • Optionally, you can now pair or re-pair your pump to the t:connect mobile app
    • For instructions on how to pair your pump with the t:connect mobile app, please visit tandemdiabetes.com/pairing
