Tutorial: Starting and Ending a CGM Sensor Session >

To start a CGM session, follow the steps below.

1. From the Home Screen, tap OPTIONS.

2. Tap My CGM.

3. Tap START SENSOR.

✓ Once you start a sensor session, the START SENSOR option is replaced with STOP SENSOR.

The following prompt displays prompting you to either enter the sensor code, or to skip this step. If you choose to enter the sensor code, you will not be prompted to calibrate for the duration of the sensor session. For information about Dexcom G6 CGM sensor codes, refer to the manufacturer’s website for applicable user guides.

If you don't have a code, you can tap skip. If you don't enter a code into either the t:slim X2 or a Mobile App, you will be prompted to calibrate your sensor every 24 hours.

4. Tap YES to confirm.

✓ The “SENSOR STARTED” screen will appear to let you know your sensor startup has begun.

✓ Your t:slim X2 will return to the CGM Home Screen with the 3 hour trend graph displayed.

5. Check your t:slim X2 Pump CGM Home Screen 10 minutes after starting your sensor session to make sure your pump and transmitter are communicating. The antenna symbol should be to the right of the battery indicator and should be white.

6. If you see the out of range symbol below the insulin level indicator, and the antenna symbol is grayed out, follow these troubleshooting tips:

  1. Make sure your t:slim X2 Pump and transmitter are within 20 feet of each other without obstruction. Re-check in 10 minutes to see if the out of range symbol is still active.
  2.  
  3. If the pump and transmitter are still not communicating, check the CGM Info screen to make sure the correct transmitter ID is entered.
  4.  
  5. If the correct transmitter ID is entered and the pump and transmitter are still not communicating, contact Tandem Diabetes Care Customer Technical Support at (877) 801-6901.

Sensor startup period

As an example, the Dexcom G6 Sensor needs a 2-hour startup period to adjust to being under your skin. You will not get sensor glucose readings or alerts until the 2-hour startup period ends and you complete your first calibrations. For information about Dexcom G6 CGM sensor startup periods, refer to the manufacturer’s website for applicable user guides.

During the startup period, the CGM Home Screen on your t:slim X2 Pump shows a 2-hour countdown symbol in the upper right portion of the screen. The countdown symbol fills in over time to show that you are getting closer to the end of the startup period.

NOTE: End Current Session Before Starting a New Session

Once your sensor session has completed, you must end the current session before you can start a new session.

Examples:

For example, if you started your sensor session 20 minutes ago, you would see this countdown symbol on the CGM Home Screen.

If you started your sensor session 90 minutes ago, you would see this countdown symbol on the CGM Home Screen.

At the end of the 2-hour startup period, if you have not entered the sensor code, then you will be prompted to enter 2 calibration values. 2 blood drops will appear in the place where the countdown symbol was. If you entered a sensor code, the countdown symbol will be replaced with the current CGM reading.

If you did not enter a sensor code, then follow the instructions in the next section to calibrate your sensor. Skip the calibration instructions if you entered a sensor code.

NOTE: Once your sensor session has completed, you must end the current session before you can start a new session.
