IMPORTANT: How to prevent missed alarms
•
Alarms must be kept on for you to receive them and you should
ensure that your Reader is within 20 feet of you at all times. The
Sensor itself will not issue alarms.
•
If the Sensor is not communicating with the Reader,
you will not receive glucose alarms, and you may miss
detecting low glucose or high glucose episodes. You will
see the
not communicating with the Reader. Make sure the Signal
Loss Alarm is on so you will be notified if your Sensor has not
communicated with the Reader for 20 minutes.
•
Make sure the Reader's sound and/or vibration settings are on
and your Reader is near you. The Home screen indicates the
sound/vibration setting when any alarm is on:
