Keep your Receiver within 20 feet (6 meters) of the Sensor/Transmitter for best
communication. To check that the Receiver and Transmitter are talking, press
the
SELECT, LEFT or RIGHT TOGGLE button to see the Trend Graph.
Note the difference between the two Antenna Symbols below:
This Antenna Symbol shows that the Transmitter
and Receiver are talking.
This Out of Range Symbol shows the
Transmitter and Receiver are not talking.
If you see the Out of Range Symbol in the
upper right corner of the screen, then review the
following troubleshooting tips.
•
Is the Receiver within 20 feet (6 meters) of your Sensor/Transmitter? If the
Receiver is not close enough, then move it within 20 feet (6 meters) of the
Sensor/Transmitter. Check in 5-10 minutes to see if the Antenna Symbol
appears and the Out of Range symbol
disappears.
•
If the Receiver and Sensor/Transmitter are still not talking, then check to make
sure the correct Transmitter ID Number is entered into your Receiver (see
Chapter 2, Section 2.4).
•
If the correct Transmitter ID has been entered into your Receiver and the
Receiver and Transmitter are still not talking, then contact DexCom.
HELPFUL HINTS:
The Transmitter and Receiver may lose communication at the following
times:
• When they are near metallic objects.
• While you are lying on a water bed.
• When you are using an electric blanket.
