2. Unknown Sensor Glucose Readings/???
In Status Box:
Sometimes the SEVEN PLUS may tell you
it cannot provide a glucose reading. Check
the placement of your Sensor to make sure
it is sticking well to your skin, and nothing is
rubbing on the Sensor. The system will display "---"when it is recording
glucose readings again.
3. Out of Range/Antenna in Status Box:
When you see the Out of Range Symbol
in the Status Box instead of a glucose
reading, this means the Receiver has
"missed" the last glucose reading sent by
the Transmitter. Move the Receiver closer to
make sure the Receiver and Transmitter are within 5 feet of each other.
If you have moved the Receiver closer and waited 5-10 minutes, the Out
of Range Symbol in the Status box should go away. The Antenna Symbol
should reappear in the lower right corner. If you are still having trouble,
contact DexCom Technical Support at 1-888-SEVENGO (738-3646).
4. Sensor Error 0/"Err0" in Status Box:
This screen means your Sensor cannot
calibrate. Enter at least 1 more calibration
fingerstick reading in the next 10-15
minutes. If "Err0" remains in the Status Box
after you enter 2 more fingersticks into the
Receiver, you may need to replace
the Sensor.

5. Sensor Error 1/"Err1" in Status Box:
This screen tells you that the Sensor is not
calibrating correctly. If you see this screen,
wait approximately one hour. Then you may
enter at least 1 more calibration fingerstick
reading. If "Err1" remains in the Status Box
after you enter 2 more fingersticks in the Receiver, you may need to
replace the Sensor.
ADDITIONAL ALERTS AND FEATURES
Alerts
Even though High and Low Glucose Alerts and the Low Glucose
ALARM (55mg/dL) are disabled in blinded mode, "Other Alerts" will
remain active (e.g. battery, calibration update, out of range).
Event Markers
You will still be able to enter event information (insulin, carbs, exercise,
health, etc.) while in Blinded Mode.
Please refer to your complete SEVEN PLUS User's Guide for
information on how to use and set these additional Alerts and use
these features.
SENSOR EXPIRATION NOTIFICATION
The Receiver displays screens that notify you how long you have until
the end of your CGM Session. You will be notified at 6 hours, 2 hours,
30 minutes, and at the end of your session.
Once the session completely counts down, press
the C button to clear the prompt, and remove the
Sensor. Glucose readings will stop recording and
the Status Box will be completely gray.
