LOW TRANSMITTER BATTERY
This screen will appear once the transmitter nears
the end of its battery life (see Chapter 1, Section 1.2,
Transmitter Overview). When the transmitter battery
is drained low enough the transmitter and receiver will
stop communicating. Contact your local distributor to
order a new transmitter.
Your transmitter battery may drain as quickly as one
week after this alert appears.

If you get this alert during a sensor session, your

OUT OF RANGE/NO ANTENNA
This screen means your receiver and transmitter are
not communicating and you are not receiving sensor
glucose readings.
• Your receiver and transmitter will only communicate
when you are in an active sensor session.
• Each time you start a new sensor session allow 10
minutes for your receiver and transmitter to start
communicating.
• You may occasionally experience loss of communication for 10 minutes at a
time. This is normal.
• If you see the out of range symbol
minutes, move your receiver and transmitter within 6 meters of each other. Wait
10 minutes and communication should be restored.

Questions and answers
The mom set a high ceiling of 300. How do I get to an actual number and not a "high" reading
You can adjust the high glucose alert value on the Dexcom G4 by following these steps:
1. Press the button to select “High Alert.”
2. Press the UP or DOWN button to highlight “On/Off” and press the SELECT button to set this option.
3. Press the LEFT button to return to the previous screen.
4. Press the DOWN button to highlight “Level.”
5. Press the SELECT button and then use the UP or DOWN button to adjust the high glucose alert value.
6. The high glucose alert value can be set between 6.7 and 22.2 mmol/L in 0.1 mmol/L increments.

This adjustment allows you to set a specific threshold instead of receiving a general "high" reading.
