Before You Begin

Basal-IQ technology only works with the Dexcom G6* continuous glucose monitor (CGM). Your t:slim X2 insulin pump will no longer be compatible with Dexcom G5 Mobile CGM following this update. If you have G5 supplies you plan to use, we recommend postponing this update until you are ready to switch to the new Dexcom G6 CGM System.

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

• Your Update ID. If you cannot locate your Update ID, contact your local Customer Technical Support.
• A backup insulin delivery option, such as a syringe and fast-acting insulin, in case there are any issues updating your insulin pump. These items should be part of your Emergency Kit and should be kept with you at all times.
• 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 software update.
