smart device. After connecting any accessories, make sure that the smart device
settings allow you to continue receiving Alarm or Alerts on the smart device.
Precautions (continued)
The following precautions may result in the consequence of missing severe hypoglycemia
(low blood glucose) or hyperglycemia (high blood glucose) or making a treatment decision that
results in injury:
Is It On?
If the receiver or smart device is turned off (Shut Down), it will not display sensor
data, information, Alarm or Alerts generated by the Dexcom G5. Make sure the
display devices are turned on; otherwise you won't get sensor glucose readings or
Alarm or Alerts.
Keep Receiver Dry
Keep the USB port cover on the receiver closed whenever the USB cable is not
attached. Do not submerge the receiver in water.
If water gets into the USB port, the receiver could become damaged and stop
displaying readings or providing alerts.
No Alternative Site Testing
Do not use alternative site blood glucose testing (blood from your palm or forearm,
etc.) for calibration. Alternative site blood glucose values may be different from
those taken from a fingerstick blood glucose test and may not represent the
timeliest blood glucose value. Use a blood glucose value taken only from a
fingerstick for calibration. Using alternative site blood glucose values for calibration
might affect Dexcom G5 accuracy.
When Not to Calibrate
Do not calibrate if your blood glucose is changing at a significant rate, typically
more than 2 mg/dL per minute. Do not calibrate when your receiver screen is
showing the rising or falling single arrow or double arrow, which indicates that your
blood glucose is rapidly rising or falling. Calibrating during rapid rise or fall of blood
glucose may affect sensor accuracy.
