Startup Calibration Needed
This symbol in the place where sensor glucose readings normally show means that you need to enter
startup calibrations. It remains on the screen until you calibrate with BG values.
Additional Calibration Required
This symbol in the place where sensor glucose readings normally show means that you need to enter
another startup calibration. It remains on the screen until you calibrate with a BG value.
Calibration Needed
This symbol to the right of the antenna means that you need to enter a calibration. It shows when it is
time for your 12-hour calibration update or any other time an additional calibration is needed.
Out of Range
This symbol in the place where sensor glucose readings normally show means that your transmitter and
pump are not communicating. The trend graph will not display sensor glucose readings. Make sure the
transmitter and pump are within 20 feet of each other without obstruction.
Glucose Reading Error
This symbol in the place where sensor glucose readings normally show means that the pump does not
understand the sensor signal but it likely to recover. This symbol relates to the sensor only. You should
wait for more prompts and do not enter any calibrations when you see this symbol.
