Getting Started with Your Replacement Pump

Before You Begin

Make sure you have your current pump settings written down or printed from the t:connect web application (My Devices, View Settings, and then Print). If you already have a t:connect account, please be sure to use your existing login credentials and do not create a new t:connect account.

Starting Your New Pump

• Using the USB cable that came with your existing pump, connect your replacement pump to a power source. This will turn the pump on for set-up.
• Enter the settings from your existing pump into your replacement pump. For a refresher on how to do this, watch this video. Refer to the Insulin Delivery Settings chapter of your user guide for more information on what pump settings are needed.
• Fill and load a new cartridge
• Resume insulin delivery

Connecting Your Dexcom CGM

Whether you are continuing a current continuous glucose monitoring (CGM) sensor session or starting a new one, you will need to disconnect your old pump from your sensor session and connect the new one by following the steps below.

But first, put your old pump into Storage Mode. In order to disconnect the old pump from your existing sensor session, it is important that you DO NOT stop the sensor session on your old pump. You can only have one pump connected to your CGM sensor session at a time.

If using a Dexcom G6 CGM

• Enter the transmitter ID into your replacement pump
• Start the sensor on your replacement pump
  (Options > My CGM > Start G6 Sensor)
• Skip the sensor code on the replacement pump
• Your replacement pump will then join the existing sensor session. It may take a few minutes for the CGM and replacement pump to connect and for numbers to populate on your t:slim X2 insulin pump.

If using a Dexcom G7 CGM

• Start the sensor on your replacement pump
  (Options > My CGM > Start G7 Sensor)
• Enter the Pairing Code as prompted
• Your replacement pump will then join the existing sensor session. It may take a few minutes for the CGM and replacement pump to connect and for numbers to populate on your t:slim X2 insulin pump.

Linking to Your Account

After you program your replacement pump, it is important to link your new pump to your existing t:connect account so that you and your healthcare provider can continue to access and review your pump data. To link your replacement pump, watch this training video or reference our Support Page.

Pairing to the t:connect Mobile App

If you used the t:connect mobile app with your old pump, open the mobile app, go to Settings, and tap Unpair Pump. Then watch this helpful video or download the instructions to pair your new pump.

If you did not use the t:connect mobile app with your old pump, the t:connect mobile app serves as a discreet secondary display for your t:slim X2 insulin pump, so you can stay informed of your diabetes management from the convenience of your smartphone. To pair your new pump to the t:connect mobile app, watch this helpful video or download the pairing instructions.

Returning Your Previous Pump

• Ensure your new pump is up and running
• Put your old pump into Storage Mode, if you haven't already in Step 3. If the On/Quick Bolus button on your old pump is not functioning, let the battery drain before sending it back to prevent the pump from beeping during shipment.
• Place your old pump in the white box that your replacement pump arrived in
• Remove the Tandem sleeve from the outside of the box and seal the white box using the enclosed pre-paid UPS return shipping label
• Drop the package off at any UPS store or UPS drop box location
