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 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.
