There are five receiver buttons to move you through the display screens that
control setup and operation and allow you to change your receiver settings. The
screens display sensor glucose readings, trend graphs and trend arrows.
Your receiver and transmitter are wirelessly paired together to communicate
securely and only with each other.
You will need a commercially available blood glucose meter to use with your
system.
