Status Symbols (continued from page before)
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
signiî‚¿cant 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.
