Now let’s insert the sensor and apply the overpatch. 

Follow the insertion instructions carefully. Extra care may help you keep your sensor on for the entire sensor session. 

Before you begin wash and dry your hands. 
 
Choose a site on the back of the upper arm with enough fat to avoid muscle, and a site that is not likely to be bumped or pushed.  
 
Clean your site with an alcohol wipe and let it dry 
 
Grab your applicator and unscrew the cap. Don’t touch inside the applicator.  
 
Push the applicator against your skin until the clear ring disappears.  

Keep it pushed in and press the button.  
 
Remove the applicator.  
 
To help keep the patch on your skin, press on the sensor for 10 seconds. Then rub around the patch 3 times. 
 
Your overpatch will help you keep the sensor on and is bundled with your instructions in the box. 
 
Carefully pull off the clear liners one at a time. Don’t touch the adhesive area.

Use the tab to place the overpatch around the sensor.  
 
You may need to look in a mirror for this part.  
 
Rub around the overpatch.  
 
Use the tab to peel off the liner.  
 
Then rub around the overpatch.  
 
Your sensor and overpatch are now complete.
