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

The question marks mean that the receiver does not understand the sensor readings for the moment. You will want to wait a minimum of three (3) hours for them to clear. If they do not clear within that time frame, please contact our Technical Support team at 1-877-339-2664 for further assistance.
