25Indications for Use and Safety Statement
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:
The Dexcom G5 Mobile will not work if you mix the transmitter and receiver from
different generations.
You can use a Dexcom G4 PLATINUM sensor with the Dexcom G5 Mobile System.
Before using the sensor, make sure the sensor label says “Dexcom G5 Mobile/G4
PLATINUM Sensor” or “Dexcom G4 PLATINUM Sensor.”
Communication Range
Do not separate the transmitter and receiver by more than 20 feet. The
transmission range from the transmitter to the receiver is up to 20 feet without
obstruction. Wireless communication does not work well through water so the
range is much less if you are in a pool, shower, etc.
Types of obstruction differ and have not been tested. If your transmitter and
receiver are farther than 20 feet 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, 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.
Using an accessory device (like a smart watch) might override your smart device
sounds. Alarm or Alerts might vibrate or be heard on the accessory instead of your
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.
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. Make sure
the display devices are turned on; otherwise you won’t get sensor glucose readings
or Alarm or Alerts.
