know what your glucose levels are—you have to teach your system what a given
BG value is by entering in a KNOWN glucose value from your BG meter.
Calibrate the Dexcom G5 Mobile at least once every 12 hours. The Dexcom G5
Mobile needs to be calibrated in order to provide accurate readings. Do not use
the Dexcom G5 Mobile for diabetes treatment decisions unless you have followed
the prompts from the device and calibrated every 12 hours after the initial
calibration.
Placement
Do not insert the sensor component of the Dexcom G5 Mobile in a site other than
the belly/abdomen (ages 2 years and older) or the upper buttocks (ages 2 to 17
years). The placement and insertion of the sensor component of the Dexcom G5
Mobile is not approved for other sites. If placed in other areas, the Dexcom G5
Mobile may not function properly.
Prior to Initial Calibration: Data/Alarm/Alert
Do not expect sensor glucose readings or Alarms/Alerts from the Dexcom G5
Mobile until after the 2-hour startup. The Dexcom G5 Mobile will NOT provide any
sensor glucose readings or Alarms/Alerts until after the 2-hour startup ends AND
you complete the startup calibration. Use fingerstick glucose values from your
blood glucose meter during the 2-hour startup.
Sensor Storage
Store the sensor at temperatures between 36°F-77°F for the length of the
sensor's shelf life. You may store the sensor in the refrigerator if it is within this
temperature range. The sensor should not be stored in the freezer.
Storing the sensor improperly might cause the sensor glucose readings to be
inaccurate.
Smart Device Settings
Your smart device's internal settings override any G5 Mobile app setting. In
addition, accessory devices (like a smart watch or other wearable smart devices)
might override your smart device's Alarm, Alert, and notification settings.
