B. Daily Calibration Phases
There are two daily calibration phases.
The 2 Daily Calibrations Phase requires a blood glucose meter test every 12 hours. Daily Calibration Phase begins after
successful completion of the Initialisation Phase.
• 12 hours after your last successful calibration, the system prompts you to calibrate.
• You may optionally enter calibrations more frequently. Daily calibration entries must be spaced at least one hour
apart.
• If you do not calibrate within 16 hours, you will receive a Calibration Past Due Alert and no glucose values will be
displayed until a calibration value is entered. After 24 hours without a calibration value entered, you will receive
a Calibration Expired Alert and the system returns to Initialisation Phase.
The 1 Daily Calibration Phase requires a blood glucose fingerstick test every 24 hours.
• 24 hours after your last successful calibration, the system prompts you to calibrate.
• You may optionally enter calibrations more frequently. Daily calibration entries must be spaced at least one hour
apart.
• If you do not calibrate within 28 hours, you will receive a Calibration Past Due Alert and no glucose values will be
displayed until a calibration value is entered. After 40 hours without a calibration value entered, you will receive
a Calibration Expired Alert and the system returns to Initialisation Phase.
