Check accessories: When using accessories such as headphones, Bluetooth
speakers, or smartwatches, you may get your alerts on only one, not all. After
connecting any accessories, make sure that your smart device settings allow you to
continue receiving alerts.
Clean and dry skin: If your insertion site and hands aren't clean and dry, you run the
risk of infection and the sensor not sticking well. Clean your insertion site with alcohol
wipes to prevent infections. Before insertion and during your sensor session, don't
apply insect repellent, sunscreen, perfume, or lotion on your insertion site or sensor.
This may cause the sensor to not stick well or could damage your Dexcom G7 CGM
System.
Be accurate, be quick: If you calibrate your Dexcom G7 CGM System using your BG
meter, enter the BG value on your meter within five minutes of measuring your BG.
Use fingertips: Use a BG sample from your fingertips when calibrating as blood
glucose from other places may be less accurate and not as timely. Calibration is not
required but you can do optional BG calibration to align with your meter.
Don't start past the Use By Date: Don't start a sensor past its Use By Date
(YYYY-MM-DD) because it may give incorrect results. You can start a new sensor on or
before its Use By Date. This gives you full wear.
Check package: Don't use your Dexcom G7 CGM System if the applicator and/or
sterile cap has been damaged or opened, because it might cause an infection. Don't
remove cap until ready for insertion.
Where to insert — things to check: The Dexcom G7 CGM System insertion safety
guard is enabled until you press the Dexcom G7 CGM System applicator down against
your skin. Only do this when ready to insert.
Change your insertion site with each sensor to allow the skin to heal.

Questions and answers
Dexcom G7 continues to show readings 50 or 60 points higher than when I stick my finger and use the supplied recorder. Why?
The Dexcom G7 may show readings 50 or 60 points higher than fingerstick measurements due to several reasons:
1. Sensor's First Day: Newly inserted sensors may show larger differences, which usually decrease over the first 24 hours.
2. Pressure on Sensor: If something is pressing on the sensor (e.g., lying on it), it can affect readings. Removing the pressure can help.
3. Rapid Glucose Changes: Blood glucose changes before interstitial fluid glucose, so fast changes can cause differences between meter and sensor readings.
4. Fingerstick Issues: Inaccurate fingerstick readings can occur if hands are not washed properly or test strips are expired or used incorrectly.
These factors can cause temporary differences between Dexcom G7 and fingerstick readings.
