How do I Update the Software on my Dexcom CGM system?

Before you begin

  1. Install the Dexcom Update Tool
  2. For a successful update, you need the following:
    • Your Receiver
    • A Dexcom supplied USB cable
    • A personal computer with Windows or Macintosh operating system with internet access
    • Authorization code(s) (if needed; see page 17 of the User Guide for more details)
  3. Make sure your receiver is charged.
  4. If you use Dexcom’s diabetes management software, use it to download your receiver data before using the update tool.
    Precaution: If you use Dexcom’s diabetes management software to view your data, use it to download your receiver data before using the update tool. Updating your receiver software using this tool will permanently erase all stored data from the receiver.
  5. Close all Dexcom computer applications (e.g. Dexcom diabetes management software).

 

Step-by-Step Instructions

  1. Launch the update tool from your desktop.
  2. Read and accept the software license agreement by clicking “YES,” then “OK”. (If the software license agreement does not appear, go to Step 3):
  3. The update tool will connect to the Dexcom servers. This happens quickly.
  4. Attach your receiver to your computer using the Dexcom-supplied USB cable. If your receiver is off, press and hold the “Select” button until it turns on
  5. Once your receiver is attached, the update tool will check for updates:
    Note: Some versions of the Dexcom receiver cannot be upgraded when connected to a USB 3.0 port. If your receiver is not compatible with USB 3.0 ports, you will be notified before beginning your receiver update.
  6. If an update is available, you will see a description. You can click “More info” for details, or simply “Select” the update:
    If no updates are available, you will see this screen and you can check back later for updates:
  7. Some updates may require an authorization code. Authorization codes are 12 character letter and number codes that can only be used once. If needed, you will receive an authorization code directly from Dexcom.
    If an update requires an authorization code, this screen will appear. Enter the code and click “OK”:
  8. The update tool will then download files.
  9. Select “Read Consent”
  10. Read and check each statement. Then click “Start Update”. Your software update will start.
  11. The update will be verified
  12. When the update is complete, the “All Done, Congratulations” screen appears. Once you see this screen, you can detach your receiver

 

After the Software Update

Your receiver will display the “Setup Wizard.” Use the receiver Setup Wizard to pair your receiver with your transmitter and to set your alerts.
