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).
