### 2\. Apply your Dexcom CGM

**💡 Pro Tip:** Applying your sensor can be intimidating, but there are ways to optimize your experience and ensure the sensor stays put! First, be sure to read this article on **[Tips for Placing Your Sensor](https://nutrisense.kustomer.help/en_us/rJsUy90kee).**

*   **Pick a spot to apply your CGM**: The Dexcom G7 CGM is applied to your upper arm. A few best practices:
    *   Choose the portion of the back of your upper arm with the most fat. Try to avoid the muscle.
    *   Avoid areas where there is scarring, tattoos, or skin irritation.
    *   Avoid areas that get bumped, pushed, or you lie on while sleeping.

![Upper arm placement guide](https://cdn.kustomerhostedcontent.com/media/67f4529145eb45782e3bdf8f/4ba6eb4eba8b0a65f3c12a2d58a89497.PNG)

*   Clean your hands with soap and water, and dry them.
*   **Clean the area on your arm**with the alcohol wipes provided, and allow it to air dry.
    *   _Skipping this step can prevent your sensor from sticking strongly to your skin._

![Skin cleaning process](https://cdn.kustomerhostedcontent.com/media/67f4529145eb45782e3bdf8f/85ff287a18f530275cd3577668eb3152.PNG)

*   Unscrew the cap of your CGM applicator. **Do not touch inside the applicator.**
*   **Use the applicator to insert your sensor**
    *   Relax your arm muscles
    *   Press and hold the applicator firmly against your skin until the clear safety guard is pushed in. Then push the button on the side of the applicator.

*   Rub around over patch
*   Use the tab to peel off the colored liner

![Liner removal](https://cdn.kustomerhostedcontent.com/media/67f4529145eb45782e3bdf8f/9e0267558476b4429b4ab96847e1f777.PNG)

*   Rub around the over patch one more time

![Final patch rubbing](https://cdn.kustomerhostedcontent.com/media/67f4529145eb45782e3bdf8f/df63e99d65f12d18c5029fbf4a031c70.PNG)

**⚠️ First 12 Hours Care:**

*   During the first 12 hours, keep your skin dry and sweat-free to improve adhesion for the full 10 days of the sensor.
*   When your patch gets wet, gently pat it dry as soon as you can.
*   If the patch peels off of your skin, trim the peeled parts and put on medical tape.

Upon initial application of the CGM, it is common to experience slight bleeding or sensations while acclimating to the device. For further information, please refer to: **[Is Wearing a CGM Painful?](https://nutrisense.kustomer.help/en_us/HkC8JqAkeg)**

### 3\. Pair and Start your Sensor

Continue following the steps provided in the Dexcom app, as follows:

*   **Enter your Pairing Code**
    *   Find and enter the 4-digit pairing code on the applicator you used to insert the sensor. You can type it in manually or take a photo.

**⚠️ We recommend taking a photo of the 4-digit code because you might need it in the future.**

![Pairing code entry](https://cdn.kustomerhostedcontent.com/media/67f4529145eb45782e3bdf8f/6f2881e1fd973a49e55792494699efa8.PNG)

*   You will see a Pairing screen with a pairing code.
    *   Accept the Bluetooth Pairing Request from DXCMUd
*   You will see a pairing completed success screen.
*   Then, your sensor will enter a warm-up period of approximately 30 minutes, as shown in the Dexcom app.
    *   During this time, keep your phone within 20 feet of your sensor without any obstructions.

![Sensor warmup screen](https://cdn.kustomerhostedcontent.com/media/67f4529145eb45782e3bdf8f/acaed0dfe86280f9fbf15a394ef9b9f2.PNG)

**When sensor warmup is complete, you will see this screen on your Dexcom App.**

![Warmup complete screen](https://cdn.kustomerhostedcontent.com/media/67f4529145eb45782e3bdf8f/60718e2570949161044b11f05a39d9eb.PNG)

#### ⚠️ Additional Precautions

**Keep Your Phone Close to Your Sensor**

*   Keep your phone within 20 feet with no obstacles (like walls or metal) between the phone and your sensor. Otherwise, they might not be able to communicate.
*   If water is between your sensor and the display device – for example, if you're showering – keep them closer to each other. The range is reduced because Bluetooth doesn't work as well through water.
*   After a disconnection, as when swimming or other activities that require separation of greater than 20 feet, reconnection may take up to 30 minutes.

### Have issues with setup?

Refer to these troubleshooting articles or **[message Customer support](https://nutrisense.kustomer.help/en_us/B1ZLy5Ayeg)** in the app for help.

*   In the event of a Failed Sensor notification during the 30-minute warm-up period, refer to the article "**[What should I do if my Dexcom CGM fails during the 30-minute warmup period?](https://nutrisense.kustomer.help/en_us/rydL1cRyxx)**" for further instructions.

**While you wait for your sensor to warm up, proceed to the next steps:**

*   Step 5: Apply the **[Nutrisense Protective Patch](https://nutrisense.kustomer.help/en_us/rJW7k9Akxx)**
