sensor pod from sticking.
- You may use medical tape (such as Blenderm, Tegaderm, IV 3000,
3M tape) over the white adhesive patch of the sensor pod, but do
not place the tape over the transmitter or the plastic parts of the
sensor pod.
13.2 CALIBRATION TROUBLESHOOTING
Calibration prompts may show during your sensor session. Review the
following troubleshooting tips for calibration.
Do not calibrate if the out of range symbol shows in the
status area.
Do not calibrate if the glucose reading error symbol shows in
the status area.
Do not calibrate if your blood glucose value is below 40 or above
400 mg/dL.
Before you take a blood glucose value for calibration, wash your
hands, make sure your glucose test strips have been stored properly
and are not expired and make sure that your meter is properly
coded (if required). Carefully apply the blood sample to the test strip
following the instructions that came with your meter or test strips.
Make sure you have not taken any medications containing
acetaminophen (such as Tylenol).
