Dexcom G6 User Manual page 50

Once you've set up your G6, it sends G6 readings to your display device every five
minutes for up to 10 days.
G6 and Previous Dexcom System Components
The G6 isn't compatible with previous generations such as the Dexcom G4 PLATINUM
CGM System or the Dexcom G5 Mobile system. You can't switch the transmitter or
sensor between the two systems. If you have an older receiver, it might need an
upgrade to use it with the G6.
PRECAUTION
Use Correct Transmitter, Receiver, and Sensor
G6 components are not compatible with any previous Dexcom products. Do not mix
transmitters, receivers, and sensors from different generations.
Follow G6 instructions. If you don't, you could have a severe low or high glucose event.
