Sensor failures can happen when your display device doesn’t receive your
sensor’s glucose readings. While it is rare to have a sensor failure, there are
preventative steps you can take.
Help prevent sensor failures by checking:
1. Sensor hasn’t expired.
2. Transmitter is snapped securely into its holder.
3. Transmitter holder isn’t dislodged or adhesive isn’t peeling.
4. Nothing is rubbing against transmitter holder (for example, seat belts).
5. You selected a good insertion site (see Chapter 6).
6. Insertion site is clean and dry before sensor insertion.

Holder
The app and receiver are ready for a new session! However, before you can
start a new sensor session, you need to end the current sensor session, and
remove the old sensor and transmitter.
Removing Transmitter Holder and Sensor
Think of the transmitter as being part of the transmitter holder. Do not remove
the transmitter before removing the transmitter holder from your body.
To remove the transmitter holder:
1. Gently peel transmitter holder adhesive patch from skin.
a. Sensor wire comes out with transmitter holder.
2. Separate the transmitter from the transmitter holder.
3. Discard the transmitter holder following your local waste management
regulations for disposing of blood-contacting parts (sensor and
transmitter holder).
Removing Transmitter From Its Holder
Remember, your transmitter is reusable, don’t throw it away until its battery
has died. With a battery life of 90 days, use the same transmitter over a
number of sensor sessions. You’ll receive notifications as it nears the end of
its battery life.
