The Dexcom G6 Receiver works with the Dexcom G6 sensor and transmitter to display glucose readings throughout the day and night. Before getting started, make sure the receiver is charged and that you have your sensor, applicator, and transmitter ready.
Always follow the instructions that came with your Dexcom G6 system. Dexcom also provides official setup guides and training materials for the receiver.
Charge and Turn On the Receiver
Before using the receiver for the first time, charge it using the supplied charging equipment.
Once it is charged, turn on the receiver and follow the instructions shown on the touchscreen. The receiver will guide you through the initial setup, including your alert settings and device information.
Enter the Sensor Code
Before inserting a new sensor, locate the sensor code printed on the sensor applicator.
Enter this code into the receiver when prompted. The sensor code allows the Dexcom G6 to operate without routine fingerstick calibration when the system is being used as directed.
Make sure you enter the code from the sensor you are actually going to use.
Enter the Transmitter Serial Number
The receiver also needs to be paired with your Dexcom G6 transmitter.
Find the transmitter serial number (SN) on the transmitter box or on the transmitter itself. Enter the serial number into the receiver when prompted and confirm that it is correct.
The transmitter sends glucose information from the sensor wirelessly to your receiver.
Insert the Sensor
Use the Dexcom G6 one-touch applicator to insert the sensor according to the instructions provided with your system.
The sensor contains a small flexible wire that sits just beneath the skin and measures glucose in the fluid surrounding your cells.
Follow Dexcom’s instructions for choosing and preparing the sensor site. Proper placement helps the sensor stay secure and work correctly.
Attach the Transmitter
After inserting the sensor, place the transmitter into the sensor holder as directed.
Make sure the transmitter is securely attached. Once connected, it communicates wirelessly with the receiver and sends glucose information throughout the sensor session.
Start a New Sensor Session
After the sensor and transmitter are in place, use the receiver to start the sensor session.
The Dexcom G6 requires a warm-up period before glucose readings become available. During this time, you will not receive G6 glucose readings or glucose alerts.
Follow the instructions displayed on the receiver while the sensor is warming up.
Viewing Your Glucose Reading
Once the warm-up is complete, your current glucose reading appears on the receiver’s touchscreen.
The receiver can show:
- Your current glucose value
- A trend arrow
- Recent glucose patterns
- High and low glucose alerts
- System notifications and alarms
The trend arrow can help you understand whether your glucose is rising, falling, or staying relatively steady.
Understanding Glucose Trends
One advantage of continuous glucose monitoring is that it provides more than a single glucose number.
For example, your current reading may be within your target range, but a downward trend arrow may show that glucose is falling. Looking at both the glucose value and the trend can give you a better picture of what is happening.
Follow the treatment instructions provided by your healthcare team when responding to glucose changes.
Setting High and Low Glucose Alerts
The Dexcom G6 Receiver can provide alerts for high and low glucose levels.
Depending on your settings, these alerts can warn you when your glucose is outside your chosen range or changing quickly.
Your healthcare provider can help you choose alert settings that are appropriate for your diabetes treatment plan.
Making Diabetes Treatment Decisions
The Dexcom G6 is designed to provide glucose information that may be used to help make treatment decisions when the system is being used according to its instructions.
However, always pay attention to how you feel as well as what the receiver shows.
If the Dexcom G6 reading or alert does not match your symptoms or expectations, Dexcom advises using a blood glucose meter to make treatment decisions.
For example, if the receiver shows a normal glucose level but you feel symptoms of very low blood sugar, confirm your glucose with a meter and follow your treatment plan.
Keep the Receiver Near You
Keep the receiver close enough to the transmitter to maintain communication.
Objects, distance, or other factors may sometimes interrupt the connection. If glucose readings disappear, check the receiver for any system messages and follow the troubleshooting instructions in the Dexcom G6 user guide.
Keep the Receiver Charged
Check the receiver’s battery level regularly and recharge it before the battery becomes completely drained.
A receiver without power cannot display your glucose readings or provide glucose alerts, so regular charging is an important part of using the system safely.
What If the Receiver Stops Showing Readings?
If the receiver is not displaying glucose readings, look for an error or status message on the screen.
Possible reasons may include a temporary communication problem, a sensor issue, the warm-up period, or a problem with the transmitter.
Follow the troubleshooting instructions displayed on the receiver or in the Dexcom G6 user guide. Dexcom provides dedicated troubleshooting guidance for pairing and sensor-related problems.
Important Safety Reminder
Use the Dexcom G6 Receiver, sensor, and transmitter according to the manufacturer’s instructions. Incorrect use of the system may cause you to miss an important high or low glucose event or make an inappropriate treatment decision.
If your glucose reading does not match how you feel, use a blood glucose meter and follow your healthcare provider’s instructions. Seek medical care when appropriate for severe or concerning high or low glucose symptoms.
