No Sync
If the Sensor is not in INIT (Initialize mode), and still working, and the Guardian RT is not synchronized,
then the screen below will be displayed. This means that the Monitor is not getting Sensor data from the
Transmitter at this point in time.
Replacing the Glucose Sensor
If the word REPLACE is displayed on the screen along with a time that is not the current time
(i.e., the time displayed is a future time), the Sensor must be changed before the next calibration is due.
The time displayed is the end of Sensor life. If REPLACE and the current time are displayed on the
screen, then the Sensor is not working and the system is no longer sending Sensor glucose values. Change
out the Sensor immediately to continue using the Guardian RT system.
