Dexcom G7 User Manual page 163

Electromagnetic interference can still occur in the home health care environment as
control over the EMC environment cannot be guaranteed. An interference event can be
recognized by gaps in sensor readings or gross inaccuracies. The user is encouraged
to try to mitigate these effects by one of the following measures:
If your symptoms do not match your sensor readings, use your BG meter when
l
making treatment decisions. If sensor readings do not consistently match your
symptoms or BG meter values, then talk to your healthcare provider about how
you should be using the Dexcom G7 to help manage your diabetes. Your
healthcare provider can help you decide how you should best use this device.
If the display device doesn't get the sensor reading twice in a row, the Signal Loss
l
banner displays. To resolve, follow the instructions on the alert screen and move
away from items that emit radio waves, such as microwave ovens, Wi-Fi hotspots,
and digital assistants.
If the receiver shows the loading screen unexpectedly and does not display the
l
trend screen within 3 minutes, contact technical support or contact your local
Dexcom distributor. For more information, see instructions on the alert screen.
