13.4 SYSTEM GLUCOSE ERROR

The system may tell you that it cannot provide a sensor glucose reading.
When this happens you will see either the glucose reading error symbol
or the wait symbol in the status area. These symbols mean
the receiver does not understand the sensor signal temporarily. These
symbols are related to the sensor only.
Wait for more prompts, and do not enter any
blood glucose values when you see these
symbols. The system will not use a blood
glucose value for calibration when these
symbols show (see Chapter 8, Section 8.3,
Glucose Status Area Symbols).
Often, the system can correct the problem and
No glucose data ( )
continue providing sensor glucose readings.
If it has been at least 3 hours since your last
sensor glucose reading, contact Technical Support (see Chapter 15,
User Assistance).
If you see these system glucose error symbols often, follow these
troubleshooting tips before inserting another sensor:
• Make sure your sensor is not expired.
