How-To Guide

• Periodic blood glucose (BG) readings using a BG meter to calibrate the sensor.
The minimum calibration is every 12 hours. For better sensor performance, it is
recommended that you calibrate your sensor three or four times each day.
You may also receive periodic requests from your pump for BG readings
without the need for calibration.
• Use of the Auto Mode Bolus feature to deliver boluses to cover meals, and
when your pump recommends a bolus.
Note: Delivering a bolus in SmartGuard Auto Mode is similar to
delivering a bolus with the Bolus Wizard feature in Manual Mode.
A BG reading above 150 mg/dL causes Auto Mode to automatically calculate if a
correction bolus is needed to bring BG down to the 150 mg/dL BG correction
target. If needed, a correction bolus will be recommended.
Manual Mode
In this user guide, the term Manual Mode refers to system functions other than
Auto Mode. In other words, if Auto Mode is not active, the system is in Manual
Mode.
Before using SmartGuard Auto Mode
SmartGuard Auto Mode can be enabled at any time, but it does not activate until
the system completes a 48-hour warm-up period while you use the pump to
deliver insulin. This warm-up period begins the midnight after the pump starts
delivering insulin and it does not require sensor use. During the warm-up period,
your Auto Mode system collects and processes data that help enable its automatic
function.
