This screen means your receiver and transmitter
are not communicating and you are not getting
sensor glucose readings.
Your receiver and transmitter only
communicate when you are in an active
sensor session.
Each time you start a new sensor session,
wait 10 minutes for your receiver and
transmitter to start communicating.
You may sometimes experience loss of communication for 10
minutes at a time. This is normal.
If you see the out of range symbol in the status area for more than
10 minutes, move your receiver and transmitter within 20 feet of
each other without obstruction. Wait 10 minutes and communication
should be restored.
You must enter your transmitter ID correctly into your receiver to
receive sensor glucose readings (see Chapter 5, Section 5.2, The
Settings Menu). Make sure you have removed your sensor and
stopped your sensor session before checking or changing your
transmitter ID. “Transmitter ID” will not appear as an option on the
Settings menu during a sensor session.
If you are still having trouble getting system readings, contact Dexcom
Technical Support (see Chapter 15, User Assistance).
