Let’s start with definitions. Then we’ll look at a Safety Statement example
used throughout the user guide, and then review the Safety Statements
broken down into the system’s components.
Safety Statement
A Safety Statement is a brief statement of the system’s indications,
contraindications (when to avoid using it), relevant warnings, and precautions.
The Safety Statements are meant to keep you and the system safe while
using the system:
How, for what purposes, and under what circumstances you should use
the system. Indications let you know who should use the system and
when. Indications are the who, what, and why of the system.
Contraindications let you know when

This section provides a review of Safety Statements containing the same
elements described above (type of Safety Statement, an action, a statement
of potential harm, and consequences) but listed in a narrative, not boxed,
format. Here you’ll learn what indications and contraindications are and what
to do to keep you safe and the system in proper working order.
Safety Statements are broken down into two major categories. First, general
CGM system Warnings, which review warnings and precautions you take with
most CGM systems; and second, Hardware/Software Warnings and
Precautions, which list warnings and precautions specific to the system
components.

Why
What are the system indications? Well, in technical terms, the indications are:
The Dexcom G5 Mobile Continuous Glucose Monitoring (CGM) System is a
glucose monitoring system indicated for detecting trends and tracking patterns
in persons (age 2 years and older) with diabetes. The system is intended for
single patient use and requires a prescription.
The system is indicated for use as an adjunctive device to complement, not
replace, information obtained from standard home glucose monitoring
devices.
The system aids in the detection of episodes of hyperglycemia and
hypoglycemia, facilitating both acute and long-term therapy adjustments,
which may minimize these excursions. Interpretation of system results should
be based on the trends and patterns seen with several sequential readings
over time.
But what does that mean? Indications are the who, what, and why of the
system.
The system is a single patient use device (meaning you can’t share the
components with others) for people age 2 years and older with diabetes.
The system is a prescription-only glucose monitoring device. system tracks
your glucose patterns and detects trends. Working with your home BG meter,
the system is meant to complement, not replace, your BG meter.
The CGM system’s trend and pattern information, its glucose Alarm/Alerts,
combined with your meter’s actual BG value, can help you manage your
diabetes.
By identifying low and high glucose level periods, the system allows you to
take action when needed and create long-term management strategies with
your healthcare professional. Using trend information to see your highs and
lows helps you stay inside your target range.

yourself or damage the system. Remember, if used during certain situations,
the risk of use may clearly outweigh any potential benefit. Within the chapters,
contraindications are in purple boxes.
Do not wear the system (sensor, transmitter, and receiver) during Magnetic
Resonance Imaging (MRI), Computed Tomography (CT) scan, or highfrequency electrical heat (diathermy) treatment.
The system hasn’t been tested during MRI, CT scans, or with diathermy
treatment. Magnetic fields and heat could damage the components, stopping
sensor glucose readings or Alarm/Alert notifications. Without sensor glucose
readings or Alarm/Alert notifications, you might miss a severe low or high
glucose event.
Taking medications with acetaminophen (such as Tylenol or Excedrin® Extra
Strength) while wearing the sensor may falsely raise your sensor glucose
readings. The level of inaccuracy depends on the amount of acetaminophen
active in your body and is different for each person.

Thoroughly review the training materials included with your system before
using.
Incorrect use could lead you to misunderstand system information or might
affect its performance and you might miss a severe low or high glucose event.
The system does not replace your BG meter.
When making treatment decisions, such as the amount of insulin you need,
only use your BG value. Don’t use the system sensor glucose readings
because they can be different from your BG value. If sensor glucose readings
are used in determining treatments, it could result in you missing a severe low
or high glucose event.
If your sensor glucose readings don’t match your symptoms, measure your
BG with a fingerstick. You may miss a severe low or high glucose event.

Significant Glucose Rate Changes
are—you have to teach your system what a given BG value is by entering in a
KNOWN glucose value from your BG meter.
Warning
Calibrate at least once every 12 hours. Calibrating less often than every 12
hours might cause sensor glucose readings to be inaccurate, resulting in you
missing a severe low or high glucose event.
Precautions
Enter the exact BG value displayed on your BG meter within five minutes of a
fingerstick.
Entering the wrong BG values, or waiting more than five minutes before entry,
might affect sensor performance, resulting in you missing a severe low or high
event.
Don’t calibrate when your BG is changing at a significant rate: more than 2
mg/dL per minute.
Look for rate of change arrows on your display device screen and don’t
calibrate when you see:
• A single arrow, pointing up
o Rising 2-3 mg/dL each minute
• Two arrows pointing up
o Rising more than 3 mg/dL each minute
• Single arrow pointing down
o Falling 2-3 mg/dL each minute
• Two arrows pointing down
o Falling more than 3 mg/dL each minute

Calibrating during a significant rise/fall of your BG may affect accuracy of
sensor glucose readings, resulting in you missing a severe low or high
glucose event.
Only use fingerstick measurements from your BG meter for calibration.
Alternative site BG values from your arms, palm of your hand, etc., may be
different and less accurate than your fingerstick BG values. Using alternative
sites for calibration might affect sensor performance, resulting in you missing
a severe low or high glucose event.
After starting a new sensor session, until completing your initial calibrations
you won’t receive any sensor information such as readings, Alarm or Alerts.
Without these, you may miss a severe low or high glucose event.
Continue to take fingerstick measurements during a new sensor warmup
period.
Now that we have reviewed common CGM Safety Statements, let’s focus on
the system components.

Clean and Dry Before Using
If a sensor wire breaks under the skin with no portion of it visible, don’t remove
it. Contact your healthcare professional if you have redness, swelling, or pain
at the insertion site.
Do not insert the sensor component of the system in a site other than the
belly/abdomen (ages 2 years and older) or the upper buttocks (ages 2 to 17
years). The placement and insertion of the system sensor is not approved for
other sites.
The system has not been tested in other areas and may not work properly if
inserted in other areas.
During a sensor’s shelf life, store it between 36° F-77° F. While you don’t need
to keep your sensor in a refrigerator, you can as long as the refrigerator is
between 36° F-77° F.
Never store sensors and/or sensor packages in a freezer.
Storing the sensor incorrectly might cause the sensor glucose readings to be
incorrect, resulting in you missing a severe low or high glucose event.
Precautions
Don’t use expired sensors. Before inserting, always check the package label
for the expiration date using the YYYY-MM-DD format.
If past the expiration date, don’t use because the sensor glucose readings
might not be accurate, resulting in you missing a severe low or high glucose
event.
Don’t use sensor if its sterile package has been damaged or opened. Using a
non-sterile sensor might cause infection.

Sensor Placement
Inspect Transmitter
Choking
Reusable: Don’t Throw Away
Before opening the sensor package, wash your hands with soap and water,
then dry. If your hands are dirty while inserting the sensor, you may
contaminate the insertion site and get an infection.
Before sensor insertion, clean the skin with alcohol wipes to prevent
infections. Don’t insert the sensor until the cleaned insertion site is dry, and
free from any lotions or perfumes.
If your insertion site is not clean and completely dry, you run the risk of
infection or the sensor pod not sticking and falling off.
Change the site where you place the sensor with each new insertion. Using
the same site too often might not allow the skin to heal, causing scarring or
skin irritation.
Sensor placement is important. Choose a site:
• At least 3 inches from insulin pump infusion set or injection site
• Away from waistband, scarring, tattoos, irritation
• Unlikely to be bumped or pushed
Insertion in these areas might affect sensor performance, resulting in you
missing a severe low or high glucose event.
Transmitter Warnings and Precautions
Warnings
If your transmitter is damaged or cracked in any way, don’t use it. Damaged
components could create an electrical safety hazard or malfunction, which
might cause electrical shocks.
The transmitter is small and may pose a choking hazard. Don’t put it in your
mouth or allow children to play with it.

System Accuracy
When ending a session, don’t throw away the transmitter.
The transmitter is reusable and can be used in multiple sensor sessions. Keep
using it until the system notifies you the transmitter battery is about to expire.
Never share your transmitter with another person. The system is a
prescription-only medical device and is meant, or indicated, for your use only.
Your transmitter is tied to
your
readings. If used by someone else, your
reports, Alarm and Alerts, etc., would be wrong, resulting in you missing a
severe low or high glucose event.
System Precautions
Next are precautions for the receiver, transmitter, sensor, and the system.
Precautions
Different generations’ transmitters and receivers aren’t interchangeable with
each other.
The Dexcom G5 Mobile CGM System transmitter and receiver are not
compatible with the Dexcom G4
receiver. The Dexcom G5 Mobile CGM System won’t work if you mix receiver
and transmitter components from different generations, resulting in you
missing a severe low or high glucose event.
You can use a Dexcom G4
CGM System. Before using the sensor, make sure the sensor label says
“Dexcom G5 Mobile/G4 PLATINUM Sensor”, or “Dexcom G4 PLATINUM
Sensor”.
System accuracy may be affected when your glucose is changing at a
significant rate such as during exercise or after a meal.

• Rising more than 3 mg/dL each minute
• Falling 2-3 mg/dL each minute
• Falling more than 3 mg/dL each minute
Be aware of airport body scanners and baggage x-rays when you travel. Do
not place any part of the system in the baggage x-ray machine or body
scanner. Ask for visual inspection instead:
• Baggage x-ray machine: Instead of putting any part of your system
through the baggage x-ray, ask the TSA officer to visually inspect it.
• Body scanner: When you are wearing your system, request hand-
wanding or full-body pat-down and visual inspection instead of going
through the Advanced Imaging Technology (AIT) body scanner (also
called a millimeter wave scanner).
The system has not been tested in x-rays or AIT body scanners, and it is
unknown if exposure to x-rays or AIT body scanners can affect the system
performance and result in you missing a severe low or high glucose event.
It is safe to wear the system for the walk-through metal detector or handwanding. If you are unsure of whether the airport scanner is a metal detector,
an AIT body scanner, or an x-ray, ask the TSA officer or request hand-
wanding or full-body pat-down.
Receiver and Smart Device Precautions
The receiver and your smart device share some precautions.
Precautions
Do not separate the transmitter from the receiver or smart device by more
than 20 feet. The transmission range from the transmitter to receiver or smart
device is up to 20 feet without obstruction.
Types of obstruction differ and not all have been tested. Obstructions can
include water, walls, metal, etc. If your transmitter and display device(s) are

more than 20 feet from each other or are separated by an obstruction, they
might not communicate, resulting in you missing a severe low or high glucose
event.
As with any wireless device, water is often the biggest culprit in reducing
communication distance. This applies to the transmitter and display devices.
Take special care when swimming, getting into a pool, bathtub, shower, etc.
When using both a receiver and a smart device, you must set your settings
separately in each. If you set up one device and then use another, you might
not get an Alarm or Alerts, causing you to miss a severe low or high glucose
event.
Using an accessory device (like a smart watch) might override your smart
device sounds. Alarm or Alerts might vibrate or be heard on the accessory
instead of your smart device. After connecting any accessories, make sure
that the smart device settings allow you to continue receiving Alarm or Alerts
on the smart device.
If the receiver or smart device is turned off (Shut Down), it will not display
sensor data, information, Alarm or Alerts. Make sure they are turned on;
otherwise you won’t get sensor glucose readings or Alarm or Alerts, causing
you to miss a severe low or high glucose event.
Smart Device Warnings
Next are warnings for just your smart device.
Warnings
The app can’t override your smart device’s internal settings. Also, accessory
devices (like a smart watch or other wearable smart devices) might override
your smart device’s Alerts and Alarm.

Getting Started:
Risks and Benefits
When using any medical device, there are risks and benefits. In this chapter,
you’ll learn what they are, so you can better understand the pros and cons of
CGM and the G5 Mobile System.
First, let’s review some possible risks.
3.1 Risks
There are some risks with using real-time CGM.
Not Receiving Alarm/Alerts
If you aren’t getting your CGM Alarm/Alerts, you run the risk of not knowing
you are having a severe glucose low or high.
Some hardware issues preventing Alarm/Alerts:
• Alert function is turned off
• Transmitter and display device are out of range
• Display device isn’t showing sensor glucose readings
• Display device battery is dead
• Unable to hear Alarm/Alerts or feel vibration
• Speaker or vibration motor not working
• App not running in the background
• Smart device is on
See Troubleshooting (Chapter 18.3) or recommended settings in Chapter 11
for more information.

1.888.738.3646
1.858.200.0200
If the sensor’s glucose reading is higher than your meter’s BG value, you may
miss a Low Alert. As an example, your last sensor glucose reading was 82
mg/dL, whereas your BG value shows 78 mg/dL. If your Low Alert is set at 80
mg/dL, you won’t receive an Alert because the sensor glucose reading is 82
mg/dL.
If you’re not receiving an Alarm/Alert, and not taking fingerstick
measurements, you may be unaware of low or high glucose levels.
Sensor Insertion Risks
Inserting the sensor and wearing the adhesive patch might cause infection,
bleeding, pain, or skin irritations (for example, redness, swelling, bruising,
itching, scarring, or skin discoloration). The chance of this happening is low.
The G5 Mobile uses the same sensor as the previous CGM system—the
Dexcom G4 PLATINUM. The Dexcom G4 PLATINUM System clinical studies
and compliance data showed slight redness and swelling occurring only in a
few patients.
During Dexcom’s G4 PLATINUM System’s clinical study, no sensor wires
broke; however, there is a remote chance a sensor wire could break or detach
and remain under your skin. Sterile broken sensor wires don’t pose a
significant medical risk.
If a sensor wire breaks off or detaches and remains under your skin, contact
your healthcare professional and call Dexcom’s Technical Support toll free,

within 24 hours.
3.2 Benefits
Daily habits impact your BG levels. With the G5 Mobile, you can track how
your exercise, carbs, stress levels, medication, or illness influence your
glucose levels.
Knowing Your Trends
Providing sensor glucose readings every five minutes, for up to seven days,
the G5 Mobile helps you detect trends and patterns. Trend information reveals

avoid dangerously low or high glucose values.
Using Dexcom
Share
(see Part 5) allows friends and family, your Followers, to
monitor your glucose activity, adding another layer of support and peace of
mind.
Helping Your Diabetes Management
Wearing the G5 Mobile on a consistent and ongoing basis helps you manage
your diabetes. The Alarm/Alerts features (see Chapter 11) keep you aware of
your glucose levels. Alerts notify you when your glucose goes outside your
target range or is rapidly falling or rising, letting you take action before you get
too low or too high. The Urgent Low Glucose Alarm lets you know when you
are dangerously or urgently low, going below 55 mg/dL. By taking corrective
measures, you reduce the time spent in your low/high range, while increasing
time in your target range (Garg, S. Z., 2006) (Battelino, T., 2011).
Real-time CGM can help improve your A1C as well as improve the quality of
your glucose control. If you are at or below 7%, using a CGM such as the G5
Mobile System helps reduce hypoglycemia (Juvenile Diabetes Research
Foundation Continuous Glucose Monitoring Study Group et al, 2008).
Lowering your A1C, increasing your time in your target range while
decreasing time in low/high BG range is believed to reduce your risk of
diabetes-related complications (Ohkubo, Y., 1995).
In some cases, patients perceived an increase in their quality of life and peace
of mind when using real-time CGM (Juvenile Diabetes Research Foundation
Continuous Glucose Monitoring Study Group, 2010).

4.3 The G5 Mobile
The G5 Mobile is a medical device you use on yourself. It allows you to
continually see your sensor glucose readings, updated every five minutes for
up to 7 days, without the bother of taking constant fingerstick measurements.
Your sensor glucose readings are measured by a single use sensor inserted
under your skin. A reusable transmitter sends your data to your display
device.
The G5 Mobile provides personalized trend Alerts, prompting you to
proactively react when your glucose levels are getting too low or too high.
Dexcom provides web-based reports reflecting your glucose trends and
patterns. Share the reports with your healthcare professional when developing
your diabetes management treatment plans.
Some users of the G5 Mobile System may need a caregiver involved in their
care. Please consult your physician for guidance.
Options to View Your Trends
The G5 Mobile transmitter works with a number of display devices, giving you
flexibility to use what’s best for you, your situation, or your lifestyle.
1. Receiver
2. G5 Mobile app on your smart device
While the system works with different smart devices, they’re not
interchangeable during a sensor session, so before starting one, select which
smart device you want to use and stick with it throughout your session. You
can’t use multiple smart devices at the same time, but you can combine the
receiver with a smart device during a session.

The G5 Mobile is the first CGM system where a smart device acts as a
receiver. For a list of current devices and operating systems go to:
Chapter 5 covers how to set up your smart device with the G5 Mobile app.
The primary difference between the receiver and app is not the information
they give you, but how that information is presented. The following are some
of the shared CGM data and system information features.
.
Tracking Real-Time CGM Data
The receiver and app give you the ability to track your glucose trends in a
number of different ways. Each device’s home screen opens to your glucose
trend screen.
View Glucose Levels
The receiver and app share many of the same glucose-monitoring features.
Your glucose values are color-coded to highlight what zone you are in,
allowing you, at a glance, to see what your levels are.
Color-coded glucose levels:
• Red - Low
• Gray - Within your target range
• Yellow – High
Trend Arrows
Glucose levels are not just about the numbers. The G5 Mobile includes trend
arrows so you know the speed and direction of your glucose, allowing you to
proactively react before your glucose gets too high or too low.
Alarm/Alerts
Being warned when your glucose value is too high or too low, falling or rising
too quickly, or trending toward a severe low or high is very important.
Warnings in the form of Alerts or an Alarm help you avoid getting too low or
high. Alarm and Alert notifications help keep you aware of your glucose trends
and are made up of a combination of sounds, vibrations, and screens.

4.5 System Information
The receiver and app also keep you informed on the system’s status.
Technical notifications provide information about your sensor session and
about the system’s hardware. Each chapter provides a table of the prompts,
system, and error messages applicable to its subject. As an example, the
Calibration chapter will review all calibration messages you may see.
Now that you know what the G5 Mobile does and what’s new, let’s open your
G5 Mobile packages, see what’s inside, and review each item.

Overview of System Components
This section is meant as a quick overview of each part; specifics for each are
found in following chapters. For detailed product specifications and technical
information, please go to Chapter 17.

Sensor Overview
For your safety, the sensor is packaged in a sterile sealed pack. When you
first open the pack, your sensor looks like one item; however, it’s actually
three: sensor applicator, sensor pod, and sensor wire.
The applicator helps you insert the sensor wire inside the sensor pod under
your skin. After inserting the sensor wire, remove the applicator. The sensor
wire stays in the sensor pod with the pod attached to your skin by adhesive.
The sensor wire is made of silver and platinum with polymer membranes.
Once inserted, the thin and flexible wire measures your glucose levels in the
fluid between your cells (interstitial fluid) for up to seven days.
This section is meant as a quick overview. More information on using and
inserting the applicator, sensor, and sensor wire can be found in Chapter 6.

Receiver
The receiver is a small hand-held device. Your receiver, as well as your smart
device, shows your sensor glucose readings, trend graphs, and trend arrows
and alerts you when your glucose is too high or too low or if there is
something you should be aware of or need to do.
The receiver is neither water resistant nor waterproof
moisture gets inside, so keep it away from any liquids and very high humidity
as well as dirt and dust. If your receiver does get wet or dirty, test it to make
sure the speaker and vibrations still work (see Chapter 12).
The small hole on the back of the receiver is not to be used to reset the
receiver. Do not push anything through the hole.
If your receiver isn’t charged, see Chapter 14 for charging your receiver’s
battery.
You can change the protective case. Just take off the black one and put on
one of the colored ones. Be sure to line up the cover’s speaker holes with the
receiver speaker.
If you want to use the receiver along with a smart device, you need to set
them up separately.
Remember, you can’t use a combination of smart devices during a sensor
session; select just one.

Let’s G5! The Basics:
Starting a Sensor Session: Inserting Sensor, AttachingTransmitter, and Starting Your Session
6.1 Introduction
Now that your display devices are set up, you’re ready to begin a sensor
session. If this is your first time inserting a sensor, you may want to watch the
sensor insertion video to get a better understanding of the process.
There are three ways to get the sensor insertion video:
1. Through the app
2. On the USB card in your receiver package
3. Online at dexcom.com:
After inserting the sensor, start the sensor warmup on your smart device and
receiver. The sensor warmup takes approximately two hours; during this time
your body is getting used to the new sensor, allowing for more accurate
sensor glucose readings. Once the two-hour sensor warmup has passed, you
enter two back-to-back fingerstick measurements to calibrate the sensor’s
glucose readings with your fingerstick measurements (Calibration is covered
in the next chapter).
Make sure you give yourself enough time to finish the startup session.
Remember your smart device’s
adding up to 30 minutes to your wait time. Good news is you don’t need to sit
around waiting: as long as you have your display device near, you can go
about your day running errands, gardening, personalizing the G5 Mobile
settings, whatever you choose during that time frame.
Keep your display device(s) handy during the warmup period—it shows how
much time has passed, notifying you with beeps and an icon when your
sensor session is ready for its initial calibrations.

If dirt or water gets into the USB port, the receiver could become
damaged and stop displaying readings or providing Alerts.

Insertion Sites
Do:
Choose a place on your belly (or if user is between the ages of 2 and 17,
upper buttocks) to insert the sensor; the site should be either above or below
your belt line. The best areas are usually flat, “pinchable,” and free from where
rubbing can occur (along the waist band, seat belt strap or where you lie when
sleeping).
For more help on ideal sensor insertion sites, contact your healthcare
professional.

What you do
• If needed, shave the area so adhesive patch sticks securely
• Make sure area is clean and free of lotions, perfumes, medications
• Never use same site repeatedly for sensor insertion
• Never use same site for 2 sensor sessions in a row
If you have concerns about the sensor pod not sticking, before inserting your
sensor, you can make the sensor site stickier to help ensure the sensor pod
does not peel.
Optional Site Preparation
Use optional skin adhesives (Mastisol™, SkinTac™) as part of your insertion
site preparation to help keep your sensor pod attached. Apply the skin
adhesive after you selected and cleaned your insertion site. Create an empty
sideways oval, making sure you don’t get any skin adhesive inside the oval.
Let the oval dry based on skin adhesive manufacturer’s instructions. Once
dry, your skin may feel slightly sticky.

The next step is attaching your transmitter to the sensor pod.
6.6 Attaching Your Transmitter
Now that you have inserted your sensor, you need to attach your transmitter.
Since the transmitter is reusable, you don’t need a new one every time you
start a sensor session. Keep your current session’s transmitter box. The
bottom label has important information you may need after you’ve attached
the transmitter. Once the transmitter has been attached, you can’t remove it
until your session is over. Chapter 8 reviews when and how to remove your
transmitter.
Before attaching your transmitter, check you’ve entered the correct transmitter
SN into your display device. Chapter 5 covers entering transmitter’s SN
number during initial setup. See Chapter 8 for pairing your transmitter after the
startup wizard

You’re almost done starting your sensor session!
Inserting the sensor, attaching the transmitter, and the two-hour sensor
warmup are the same regardless of whether you use the receiver or app.
No matter which display device you use, you’ll insert the sensor and attach
the transmitter only once during your seven-day sensor session.
The remaining steps vary from app to receiver:
1. Letting your device know you need to start the sensor warmup.
2. Following your warmup countdown.
Make sure none of the transmitter’s sides

• Don’t tape over the transmitter or any plastic parts of the sensor pod
• Don’t tape under sensor pod
• Don’t leave any substance on the skin where you insert the sensor
Figure 4. The Right Way to Use Tape for Extra Support
6.8 Starting Your Sensor Session
If you choose to use both the receiver and the app, each system requires
individual setups (see Chapter 5).
After pairing the transmitter to your display device(s), inserting your sensor,
and attaching the transmitter to the sensor pod, your next step is telling your
device(s) you want to start a sensor session. Transmitters are reusable;
pairing is required only when using a new transmitter.
During the warmup period, neither device will provide any sensor glucose
readings. Your sensor glucose readings begin after the two-hour sensor
warmup has passed and you entered the initial two calibration BG values into
either the smart device or the receiver.
We’ll first review starting the sensor session for the app.
