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-
or 24-hour calibration update or any other time an
additional calibration is needed.
Wait 15 Minute Calibration Error
This symbol in the place where sensor glucose readings
normally show means that the sensor cannot calibrate right
now. If you see this, enter at least one more calibration
blood glucose value after 15 minutes. If the sensor still
cannot calibrate after that, the sensor needs to be removed
and a new sensor needs to be inserted.
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.

Sensor Session Ended
This symbol in the place where sensor glucose readings
normally show means that your sensor session has ended.
Failed Transmitter
This symbol in the place where sensor glucose readings
normally show means that the transmitter has failed. The
transmitter needs to be replaced.
Failed Sensor
This symbol in the place where sensor glucose readings
normally show means that the sensor has failed. The sensor
needs to be removed and a new sensor needs to be
inserted.
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.
