Tandem Device Updater

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.  

t:slim Pump update

This update, available for t:slim Pumps purchased before April 2015, includes an expansion of the reverse correction functionality, the ability to enter a manual bolus directly in the suggested bolus window, off-pump cartridge filling, and other features that enhance convenience and flexibility. Pumps purchased after April 2015 already include these updates.

Get ready

Before you begin, please consult the Tandem Device Updater User Guide and make sure you have the following on hand:

  • Your unique Update ID Number, sent to you in an email. If you did not receive an email from us, give our Customer Support Team a call at (877) 801-6901. The Software Support Team is available between 6:00 AM to 6:00 PM Pacific Time.
  • A backup insulin delivery option, such as a syringe and fast-acting insulin, in case there are any issues updating your pump.
  • Your blood glucose meter so that you can check your BG prior to starting the update.
  • A convenient time to stop all insulin delivery, detach your infusion set, and remove your cartridge. We recommend performing the update when you are ready to change your cartridge.
  • A computer with an internet connection. If you are using a laptop, make sure that it remains plugged in to a wall outlet during the half hour it will take to complete the update.
  • And remember, the t:flex and t:slim G4 pumps are not currently compatible with the Tandem Device Updater.
