Cause: Calibration is needed. No new glucose values will be recorded until calibration is done.
Calibration value must be between 40-400 mg/dl (2.22-22.2 mmol/l). This alarm is triggered if
calibration has not been done in the last 12 hours or following a CAL ERR alarm, or if a
calibration has not been done in the last 8 hours since the first calibration.
Action: Press the SEL button and then the ACT button to clear the alarm. Take a fingerstick reading using a
meter. Press the SEL button until the METER BG screen appears. Press the ACT button, and the dashes “-
--” will blink. Press the Up or Down arrow button to scroll through the values until meter value is
displayed. Press the ACT button to confirm. Until calibration is done, this alarm will repeat hourly.
