Setting up your MiniMed Flex replacement pump

Write down your current pump settings
You'll need to confirm that your settings transferred correctly after updating your pump. To do this, you will need to have your current settings written down. Use the settings transfer form to find and write down your settings.

Sync your data to CareLink^TM Personal
It is recommended to sync your existing pump data to your CareLink^TM Personal account before completing the update. This uploads your data to the CareLink^TM cloud making sure your recent pump data and current settings are saved. Use the MiniMed^TM app and follow these steps:

1. From the MiniMed app, tap 
2. Tap Carelink.
3. Tap Upload now and let the system complete the upload before leaving your app

Unpair your existing pump
You will need to unpair your previous pump before pairing your new replacement pump. Follow these instructions to unpair your old pump. Return to this page once the pump is unpaired.

Fully charge your pump before starting the update. If charge drops below 70%, the update cannot proceed. Your pump can remain on the charger during the update.

Download the update
Downloading the software update can take up to 15 minutes. You may see your time remaining go up or down depending on your internet connection and phone use. It's important to keep the app open in the background. You can use other apps and phone functions.
