1 • Welcome
Thanks for choosing the Dexcom G7 Continuous Glucose Monitoring (CGM) System (G7)! Using
this medical device, you'll see your glucose readings on your display device just by wearing a
tiny sensor!
Here are some of the benefits of using G7 to manage your glucose:
lNo more fingersticks: G7 allows you to make treatment decisions without fingersticks. (If
your glucose alerts and readings from the G7 do not match symptoms or expectations, use
a blood glucose meter to make diabetes treatment decisions.)
lPredict and prevent highs and lows: With G7, you have the information needed to keep
your glucose in range, you can customize your alert schedule, and you get a 20-minute
warning when your glucose is quickly heading towards 55mg/dL.
1 • Welcome | Dexcom G7 Using Your Receiver 1

lStay informed: See the results of your actions in the summary reports and keep
improving.
So let's get started!
Get started
To set up your G7, use the instructions in your Receiver: Start Here
guide.

To insert your sensor, use the Inserting Sensor instructions at the
bottom of Start Here in the sensor box.
This G7 Using Your Receiver Guide introduces you to the display device screens, leads you
through making treatment decisions, and shows you how to move to your next sensor session.

2 • Safety Information for the Dexcom
Receiver
Important user information
Read the indications, warnings, precautions, and instructions for your Dexcom G7 CGM System.
If you don't, you may have inaccurate sensor readings, missed alerts, and might miss a severe
low or high glucose event.
Warnings
Read product instructions before you use your Dexcom G7 CGM System: For safety
information for other Dexcom G7 CGM System components and the complete Dexcom G7 CGM
System, go to the safety information provided with each sensor.
2 • Safety Information for the Dexcom Receiver | Dexcom G7 Using Your Receiver 5

Inspect: Don't use any damaged or cracked Dexcom G7 CGM System component because it
may not work correctly and could cause injuries from electrical shocks.
Use electrical equipment as directed:
Use of accessories, cables, adapters, and chargers other than those specified or
provided by the manufacturer of this equipment could result in increased
electromagnetic emissions or decreased electromagnetic immunity of this equipment
and result in improper operation.
Portable radio frequency communications equipment (including peripherals such as antenna
cables and external antennas) should be used no closer than 12 inches to any part of the
Dexcom G7 CGM System including cables specified by the manufacturer. Otherwise,
degradation of the performance of this equipment could result.
Use of this equipment adjacent to, or stacked with, other equipment should be avoided because
it could result in improper operation.
6

Not using supplied USB charger and cable may cause the receiver battery to not charge. Don't
use if the supplied USB charger or cable is damaged. Store supplied USB charger and cable
safely. Misuse of the USB cable can be a strangulation risk.
Do not Modify: No modifications to the Dexcom G7 CGM System are allowed.
Precautions
Get alerts on display device you use: To get your alerts, set them on the display device you
use. Your receiver won't get the alerts you set in your app. Likewise, your app won't get the
alerts you set on your receiver.
Test speaker and vibrations: Test your receiver speaker and vibrations regularly.
To make sure the speaker and vibrations work, plug in the receiver to charge. The Speaker Test
screen appears for a few seconds. Follow the directions on the screen to test the speaker and
vibrations. If it doesn't beep and vibrate, contact technical support (in the app, go to Profile >
Contact) and use your app or BG meter until the receiver is fixed.
2 • Safety Information for the Dexcom Receiver | Dexcom G7 Using Your Receiver 7

Keep receiver clean and dry: Don't submerge your receiver in water and don't get dirt or
water in the USB port. That could damage it.
Display device is on: Make sure your display device is turned on or you won't receive sensor
readings or alerts.
Use correct components: Dexcom G7 CGM System components aren't compatible with any
previous Dexcom products. Don't mix with different generations.
Tip
Use G7 receiver: If you use the Dexcom receiver, be sure to use the one that comes with your
Dexcom G7 CGM System. Receivers from previous generations won't work with the Dexcom G7
CGM System.

Glossary
A1C Blood test used to diagnose type 1 or type 2 diabetes and to gauge
how well you're managing your diabetes. A1C reflects your average
blood glucose level for the past 2 to 3months.
Alternative Site
Testing
Testing a blood sample from non-fingertip (alternate) sites for BG
meter values. Only use fingertip tests to calibrate G7.
Blood Glucose (BG)
Meter
A medical device used to measure how much glucose is in the blood.
Blood Glucose (BG)
Meter Value
The amount of glucose in the blood measured by a BG meter.
2 • Safety Information for the Dexcom Receiver | Dexcom G7 Using Your Receiver 9

Calibration When you calibrate your G7 using your BG meter, you take a fingerstick
measurement from your BG meter then enter the value into your
receiver or smart device.
Calibrating your G7 using your BG meter is optional. Calibration with
your BG meter may align your sensor readings with your BG meter
values.
Continuous
Glucose
Monitoring (CGM)
A sensor inserted under the skin checks glucose levels in interstitial
fluid and sends sensor readings to a display device.
Contraindication A situation where G7 shouldn't be used because it may be harmful to
you. The risk of use outweighs the benefit.
10

Default A manufacturer’s preset option for a device setting.
Display Device A device with a screen used for monitoring your glucose information
and alerts, for example, a smartphone app or the Dexcom receiver.
Glucose Alerts Alerts related to your glucose, including: Falling Fast, High Glucose,
Low Glucose, Rising Fast, Urgent Low, Urgent Low Soon

GMI (Glucose
Management
Indicator)
Glucose Management Indicator (GMI) is calculated using your average
sensor glucose data. GMI can be an indicator of how well you are
managing your glucose levels. Your GMI will likely differ from your
A1C.
Reference: Bergenstal, Richard M. et al. "Glucose Management
Indicator (GMI): A New Term for Estimating A1C From Continuous
Glucose Monitoring." Diabetes Care, ADA, November 2018.
Grace Period An extra 12-hour period after the sensor session that gives you more
time to replace your sensor. Your system works exactly as it did during
your sensor session.
