Why did I receive two transmitters?
You have received two Dexcom G5 Mobile transmitters to support a six month supply. Each transmitter will last three months.
Please only use ONE transmitter to get started. Do not remove the second transmitter from the box until it is ready to be used. Once you see the transmitter “Low Battery” screen, replace the transmitter as soon as possible. Your transmitter battery may drain as quickly as one week after this alert appears.
