Communication Range; Setting Alarm/Alert Notifications; Keep Receiver Dry; No Alternative Site Testing - Dexcom G5 mobile User Manual

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:

Communication Range

Avoid separating the transmitter and receiver by more than 6 meters. The transmission
range from the transmitter to the receiver is up to 6 meters without obstruction.
Wireless communication does not work well through water so the range is much less if
you are in a pool, bathtub, or on a water bed, etc.
Types of obstruction differ and have not been tested. If your transmitter and receiver
are farther than 6 meters apart or are separated by an obstruction, they might not
communicate or the communication distance may be shorter.

Setting Alarm/Alert Notifications

When using both a receiver and a smart device with your Dexcom G5 Mobile CGM
System, you must set your settings separately in each. If you set up one device and then
use another, you might not get an Alarm or Alert.
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 Mobile CGM System. Make
sure the Display Devices are turned on; otherwise you will not 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 blood glucose site testing (blood from your palm or forearm, etc.)
for calibration. Alternative site blood glucose values may be different than those taken
from a fingerstick blood glucose value and may not represent the timeliest blood glucose
value. Use a blood glucose value taken only from a fingerstick for calibration. Alternative
site blood glucose values might affect the Dexcom G5 Mobile CGM System's accuracy.
