Calibration Needed
This symbol means you need to enter a calibration. This prompt will show when it is
time for your 12-hour calibration update or any other time an additional calibration is
needed (see Chapter 7, Section 7.2, How to Calibrate).
Additional
Calibration Needed
This symbol means you need to enter one more blood glucose value in order to
calibrate the system and start getting sensor glucose readings.
Glucose Reading
Error
This symbol means the receiver does not understand the sensor signal but is likely
to recover. This symbol is related to the sensor only. You should wait for more
prompts and
do not enter
any blood glucose values when you see this symbol (see
Chapter 13, Section 13.4, System Glucose Error for more information).
Out of Range
This symbol means the receiver and sensor/transmitter are not communicating.
Make sure the receiver and sensor/transmitter are within 20 feet of each other
without obstruction (see Chapter 1, Section 1.4, Transmitter Overview).
Wait 15 Minutes
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.
Wait 1 Hour
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 significant 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.
Status symbols show in the upper right of your trend graph.
