70 | Continuous Glucose Monitoring System

HELPFUL HINTS:

• You can set an Out of Range Alert to notify you when the Receiver and

Sensor/Transmitter are not talking (see Chapter 8, Section 8.6). You can

also set the amount of time the Transmitter can be out of range before the

Receiver alerts you.

• The Sensor/Transmitter and Receiver may lose communication during the

following circumstances: while you are lying on a waterbed, while you are

near other metallic objects, or when you are using an electric blanket.

5.4.4 OUT OF RANGE/NO ANTENNA

•

When you see the Out of Range Symbol

in the Status Area, this means the

Receiver has “missed” the last glucose reading sent by the Transmitter.

• If you see this Symbol, make sure the Receiver is

within 20 feet (6 meters) of the Sensor/Transmitter.

If not, move the Receiver closer and wait at least

5 minutes.

•

Once you have moved the Receiver closer and

waited 5-10 minutes, the Out of Range Symbol

in the Status Area should disappear. The Antenna

Symbol

should reappear in the upper left corner,

and you should receive a glucose reading.

•

If you are still having trouble receiving System readings because of this

problem, contact DexCom Technical Support.
