NOTE
If you have not received any glucose readings in the past hour and have attempted
re-calibration by taking and uploading at least 3 BG fingersticks then contact DexCom
Technical Support at 1-877-DEXCOM4 (339-2664) as there may be a problem with your
Sensor.
Take another BG fingerstick and enter this information to the Receiver. After you •
do this your Seven System will take about 10-15 minutes to update calibration. e
blood drop symbol will remain in the upper right corner during the 10-15 minute
period.
After successful re-calibration your Seven System will display glucose readings, trends
•
and provide Alerts and ALARMs again.
