Calibration may be denied under the following conditions:
l During the system recovery or warm-up phase.
l For factory-calibrated items, calibration is not recommended within the first 48 hours. Only calibrate if there is a significant difference between BG readings and device readings.
l Calibration is restricted during the first 24 hours after device activation.
l If the calibration value exceeds the algorithm's Coefficient of Variation (CV) limits.
