SENSOR INSERTION

Once you have placed the applicator on your belly and removed the safety lock,
you are ready to insert the sensor. To insert your sensor follow the steps below:
1. Using one hand, you may want to pinch up on the skin, at the edge of the
white adhesive. Do not pinch up in the middle section of the plastic base. With
your other hand, place two fingers above the collar on the applicator barrel so
they are resting above the collar.
2. Place your thumb on the white plunger. Push the plunger down completely,
making sure it is flush against the applicator barrel. You should hear 2 clicks.
This action inserts the needle and sensor under your skin.
When you are pushing down on the plunger, do not pull back on the collar.
Push down the plunger – Insert the needle and sensor
3. To remove the sensor introducer needle,
keep pinching up on your skin with one hand.
With your other hand, place two fingers
under the collar. Keep your thumb lightly on
top of the white plunger and pull the collar
back towards your thumb until you hear 2
"clicks" or can not pull back any more. This
step leaves the sensor under your skin and
removes the sensor introducer needle from
your body.
