There are a number of reasons why you may not get rate of change arrows:
• You just started your sensor session
• No sensor glucose readings over the last few minutes

9.5 Error Messages

Sometimes the transmitter, or sensor, or display devices aren't communicating, causing you
not to get your sensor glucose readings or rate of change arrows. Each device notifies you
when there is an issue; however, the notifications look different.
Before the system can move forward, you need to address the error.
