Each part comes in its own package. Keep the packaging until you're no longer using its contents.
Sensor Overview
For your safety, the single-use sensor is packaged in a sterile sealed pouch. When you open the package,
your sensor looks like one item, but it's actually three: sensor applicator, transmitter holder, and sensor wire.
The applicator helps you insert the sensor wire under your skin. After inserting the sensor wire, you can throw
away the applicator. You'll see the transmitter holder held onto your body with the adhesive patch. The
sensor wire is attached to the other side of the holder.
Once inserted, the sensor's thin, flexible wire measures your glucose levels in the fluid between your cells
(interstitial fluid) for up to 10 days.

Transmitter Overview
The front and back of the transmitter look like this:
The transmitter snaps into the transmitter holder and wirelessly sends your glucose information to your
display device(s).
The transmitter is reuseable. If you have a new transmitter, open the package when you're ready to use it.
