Precaution
Don’t: Never mix the Dexcom G5 transmitter or Dexcom G5 receiver with the Dexcom
G4 PLATINUM transmitter or receiver.
Why: The Dexcom G5 transmitter and receiver are not compatible with the Dexcom
G4 PLATINUM transmitter and receiver. The Dexcom G5 won't work if you mix receiver
and transmitter components from different generations.
Consequences: Missing a severe low or high blood glucose event or making a
treatment decision that results in injury.
5.3 Why Different Monitoring Methods?
Your convenience!
By offering two separate monitoring systems, the app or receiver, you can choose to monitor
your glucose levels in the handiest method at that moment. Forgot your receiver at home?
Use your smart device! Battery died on your smart device? Smart device memory full or out
of storage space? Your receiver has you covered!
With the exception of Dexcom Share, the primary difference between the two monitoring
systems is not the data itself, but how it’s presented.
The next section walks you through the initial setup for the app. To set up the receiver, go to
Section 5.5. If you want to use both the G5 Mobile app and the receiver, you need to set up
each individually.
Once you have completed the initial setup, you’re one step closer to beginning your sensor
session!
5.4 G5 Mobile App
Before starting your first sensor session, pick which smart device you want to use. As
mentioned in the previous chapter, you can use the receiver with one smart device during a
session; however, you can’t use multiple smart devices during the same session.
While your smart device can have the app installed, part of your initial setup is entering the
transmitter’s serial number (SN). If by accident you enter the SN into more than one smart
device, the system warns you and you won’t be able to complete the setup process.
