Dexcom G5 Getting Started Manual page 12

The Dexcom G5's transmitter and receiver are not compatible with the Dexcom
G4 PLATINUM CGM System's transmitter and receiver. The Dexcom G5 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 System. Before using
the sensor, make sure the sensor label says "Dexcom G5 Mobile/G4
PLATINUM Sensor" or "Dexcom G4 PLATINUM Sensor."
Communication Range
Avoid separating 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, 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. Alarms 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 Alarms 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. 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.
