sensor pod from sticking.
- You may use medical tape (such as Blenderm, Tegaderm, Smith

sensor pod, but do not place the tape over the transmitter or the
plastic parts of the sensor pod.

• Before you take a blood glucose value for calibration, wash hands,
make sure the glucose test strips have been stored properly and
are not expired and make sure that the meter is properly coded (if
required). Carefully apply the blood sample to the test strip following
the instructions that came with the meter or test strips.
• Make sure you have not taken any medications containing
