What do the Question Marks (???) mean?

The question marks mean that the transmitter does not understand the sensor readings for the moment. You will want to wait a minimum of 3 hours for them to clear. If they do not clear within that time frame, please contact Dexcom Technical Support at 1-844-832-1810 (Option 3).
