Calibration
Error
This symbol means the sensor is not calibrating correctly. If you see
this screen, wait a minimum of one hour and then enter one more blood
glucose value. If no readings display on the receiver after this, the
sensor needs to be removed and a new sensor needs to be inserted.
Wait
This symbol means the receiver has detected a potential signicant
problem with the sensor signal and may result in a sensor failure. You
should wait about 30 minutes for more prompts. Do not enter any blood
glucose values when you see this symbol.

Calibration
Error
This symbol means the sensor cannot calibrate right now. If you see
this screen, enter at least one more calibration blood glucose value after
about 10-15 minutes. If the sensor still cannot calibrate after that, the
sensor needs to be removed and a new sensor needs to be inserted.
