Signal Loss
System alert: When you have a system alert (such as Signal Loss,
shown here) you won't get a sensor reading or arrow. Use your BG
meter to treat.
Symptoms don't match sensor readings
When how you feel doesn't match your sensor reading, use your BG meter to treat even if you
have a number and arrow. In other words, when in doubt, get your BG meter out.
For example, you don't feel good, but your sensor readings show you're in range. Wash your
hands thoroughly and use your BG meter. If the BG meter value matches your symptoms, use
the BG meter value to treat.
