Starting Your Sensor Starting Your Sensor
IMPORTANT: IMPORTANT:
• The App requires that your smartphone be set to network time. This is the
default time setting for most smartphones.
• When using the App, you should keep your smartphone well charged and be
sure you have access to a blood glucose meter.
• Make sure your smartphone's sound is set so you can hear scan sounds or
alarms if you turned those on.
• Keep in mind that the ease of scanning a Sensor may vary between devices.
Once you determine the location of the NFC (Near Field Communication)
antenna on your smartphone, you should be able to reliably scan your Sensor
by holding that area near your Sensor. You may need to adjust your scan
distance based on what clothing you are wearing. In addition to proximity and
orientation, other factors can affect NFC performance. For example, a bulky or
metallic case can interfere with the NFC signal.
1. Hold the back of your smartphone near the Sensor (this can be done over
clothing) and position the NFC antenna over the Sensor. Do not move the
smartphone until you hear the first tone and/or feel a vibration. This indicates
your smartphone and Sensor have established an NFC connection.
