You’ll even learn what a contraindication is! 2.2 Important User Information Each part of your system has instructions including indications, contraindications, warnings, precautions, and other important user information. Please review the instructions for each part of the system in this user guide before using the system.  This chapter is important to read. It helps you use the system safely and covers: • What is a Safety Statement? o Telling the difference between an indication and a contraindication o Explaining why warnings are so important o Defining precautions • How to read a chapter’s Safety Statement • Overview of Safety Statements
 Dexcom G5 Mobile System User Guide Risks and Benefits 21 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: 1) Indications 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. 2) Contraindications Contraindications let you know when not to use the system. If used during these situations, you may hurt yourself or the system, the risk of use clearly outweighs the benefit.  3) Warning Important hazard information: Describes serious or life- threatening circumstances to stay away from while using the system, their consequences, and how to avoid danger. 4) Precaution Special steps you need to take while using the system preventing minor or moderate injury to either you or the system.  2.3 Safety Statements This user guide presents Safety Statements two ways: 1. In this chapter’s Overview of Safety Statements o Lists all Safety Statements o Includes a section reviewing how the statements are formatted 2. Within each chapter
 Dexcom G5 Mobile System User Guide Risks and Benefits 22 o Lists only those statements applicable to that specific chapter Chapter’s Safety Statements  Each chapter will list all applicable indications, contraindications, precautions, and warnings. Some chapters will have multiple Safety Statements; others have none. Safety Statements are located toward the beginning so you can keep them in mind as you learn about that chapter’s topic. The same statement may be repeated throughout the user guide. It’s important to recognize which factors could prevent the system from working correctly, or even harm you. Within chapters, each color-coded Safety Statement is in a box, broken down into four sections: 1. Type of statement a. Bold and color-coded • INDICATION-Green • CONTRAINDICATION-Purple • WARNING-Red • PRECAUTION-Blue 2. Do’s/Don’ts a. An action you should or should not take b. Italicized 3. Why a. A statement of the potential harm 4. Consequences a. What could happen if you don’t follow the instructions
 Dexcom G5 Mobile System User Guide Risks and Benefits 23 The following is an example of a chapter’s Safety Statement and how to read it. Warning Do: Calibrate at least once every 12 hours Why: Calibrating less often than every 12 hours might cause inaccurate sensor glucose readings  Consequences: Missing severe low (hypoglycemia ) or high (hyperglycemia) Alarm or Alerts  Since this is a Warning, you know it covers important safety information. Italics are the Do/Don’t steps to follow: Calibrate at least once every 12 hours. Below the italics is a statement explaining Why you need to follow the steps: Calibrating less often than every 12 hours might cause inaccurate sensor glucose readings. And finally what happens, or the Consequences, if you don’t: Missing a severe low (hypoglycemia) or high (hyperglycemia) Alarm or Alerts. 2.4 Overview of Safety Statements 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.   Indications and Contraindications Indications
 Dexcom G5 Mobile System User Guide Risks and Benefits 24 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. In Layman’s Terms But what does that mean? Indications are the who, what, and why of the system.  Who 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. What 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. Why 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.
 Dexcom G5 Mobile System User Guide Risks and Benefits 25 The system’s trend and pattern information is based on a series of sensor glucose readings taken over a period of time. Work with your healthcare professional and create a game plan on how to best use your trend and pattern information in managing your diabetes. Contraindications Contraindications let you know when not to use the system; you may hurt 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.  MRI/CT/Diathermy   Do not wear the system (sensor, transmitter, and receiver) during Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scan, or high-frequency 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. Medications 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. 2.5 General CGM System Warnings Warnings Warnings outline important hazard information, describing any serious and/or life-threatening situations, their consequences, how to avoid danger while using the system and how to protect the system from harm.
 Dexcom G5 Mobile System User Guide Risks and Benefits 26 Review Training Materials 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. Treatment Decisions 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. Don’t Ignore Low/High Symptoms 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. Who Shouldn’t Use The system was not evaluated for the following persons: • Pregnant women • Persons on dialysis Do not use the system in critically ill patients. It is not known how different conditions or medications common to the critically ill population may affect the performance of the system. Sensor glucose readings may be inaccurate in critically ill patients. The system’s accuracy hasn’t been tested in people falling into these groups and sensor glucose readings may be inaccurate, resulting in missing a severe low or high event. 2.6 Calibration Warning and Precautions Calibration is the process of making sure your sensor continues to be accurate. Your sensor doesn’t automatically know what your glucose levels
 Dexcom G5 Mobile System User Guide Risks and Benefits 27 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 on Schedule 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 Be Accurate, Be Quick 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. Significant Glucose Rate Changes 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
 Dexcom G5 Mobile System User Guide Risks and Benefits 28 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. Fingerstick Only 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. Prior to Initial Calibration: Data/Alarm/Alert 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.  2.7 System/Hardware/Software Warnings and Precautions In this section, you will learn how to safely use the system’s hardware and software. Some sections will have either Precautions or Warnings, others will have both.

Contact your healthcare professional if you have redness, swelling, or pain at the insertion site. Placement 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.  Storage 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 Expiration Date 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. Sensor Package Don’t use sensor if its sterile package has been damaged or opened. Using a non-sterile sensor might cause infection. Clean and Dry Before Using
 Dexcom G5 Mobile System User Guide Risks and Benefits 30 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.  Sensor Placement 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 Inspect Transmitter 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. Choking The transmitter is small and may pose a choking hazard. Don’t put it in your mouth or allow children to play with it.  Precaution Reusable: Don’t Throw Away
 Dexcom G5 Mobile System User Guide Risks and Benefits 31 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. Don’t Share Your Transmitter 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 Use Correct Transmitter, Receiver, and Sensor 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® PLATINUM CGM System’s transmitter and 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® PLATINUM Sensor with the Dexcom G5 Mobile 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 System accuracy may be affected when your glucose is changing at a significant rate such as during exercise or after a meal.  Significant glucose rise/fall rates: • Rising 2-3 mg/dL each minute
 Dexcom G5 Mobile System User Guide Risks and Benefits 32 • Rising more than 3 mg/dL each minute • Falling 2-3 mg/dL each minute • Falling more than 3 mg/dL each minute Airport Scanners 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 hand-wanding. 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 Communication Range 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
 Dexcom G5 Mobile System User Guide Risks and Benefits 33 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. Setting Alarm/Alert Notifications 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. Is It On? 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 Smart Device Settings 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. To receive Alarm or Alerts you must: 1. Make sure app Notifications are turned on in the Settings menu.
 Dexcom G5 Mobile System User Guide Risks and Benefits 34 2. Verify app hasn’t been shut down. 3. Turn on Bluetooth. 4. Turn off Do Not Disturb (if available on your smart device). 5. Restart app after device is restarted. 6. Set Volume at a level you can hear. 7. Do not close app; always run app in the background. 8. Make sure accessory devices do not override your smart device settings. If your settings are incorrect, you might miss a severe low or high glucose event. App Alarm/Alert vibrations aren’t any different from other vibrating apps on your smart device. Medical device apps, like this app, don’t have any special priorities over your smart device’s features. App notifications or Alerts may sound or feel the same as notifications from another app. The only way to know is to look at the screen. Did You Miss an Alarm or Alert? An Alarm or Alert can’t be heard through your smart device’s speakers if headphones are connected.  Make sure you disconnect your headphones when you are done using them, otherwise you might not hear an Alarm or Alert, causing you to miss a severe low or high glucose event. Receiver Warning and Precautions Warning Don’t Use Damaged Goods If your receiver is damaged or cracked, don’t use it. This could create an electrical safety hazard or malfunction, causing possible electrical shocks.  Avoid Strangulation
 Dexcom G5 Mobile System User Guide Risks and Benefits 35 Use USB cable only as directed and store safely. Misuse of the USB cable can present a strangulation risk. Precautions Test Receiver Shortly after the receiver is powered on or plugged in to charge, it should briefly vibrate and beep. If this doesn’t happen, it may mean the vibration motor and/or speaker are not functioning properly. Please retry. If it still doesn’t vibrate and beep, contact Technical Support.  If your receiver gets wet or dropped, make sure the speaker and vibrations still work. To check, either plug it in, turn it on, or go to the Sounds menu and select Try It. If it doesn’t vibrate and beep, contact Technical Support.  If the vibration motor and/or speaker on your receiver is not functioning properly you may miss a severe low or high Alarm/Alert. Use the app on your smart device until this issue is resolved.  Keep Receiver Clean and Dry Do not get dirt or water in the USB port and do not submerge in water. If dirt or water gets into the USB port, the receiver could become damaged and stop displaying readings or providing Alerts; you might miss a severe low or high glucose event. Caution U.S. law restricts the sale of the system to sale by or on order of a physician. Summary Now You Can: • Define a Safety Statement • Explain the difference between an indication and a contraindication Describe what a precaution is • Describe the importance of warnings Correctly read a chapter’s Safety Statement
 Dexcom G5 Mobile System User Guide Risks and Benefits 36 • Provide an overview of Safety Statements by category What’s Next? In our next chapter, you will learn about the risks and benefits of using the system.
 Dexcom G5 Mobile System User Guide Risks and Benefits 37 Chapter 3 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 Do Not Disturb or Silent Mode See Troubleshooting (Chapter 18.3) or recommended settings in Chapter 11 for more information.  Different Devices May Give Different Numbers The sensor glucose reading can be different from your meter’s BG value.
 Dexcom G5 Mobile System User Guide Risks and Benefits 38 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, 24/7, at 1.888.738.3646 or toll at 1.858.200.0200 within 24 hours.  Those are the risks, let’s now review the benefits! 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
 Dexcom G5 Mobile System User Guide Risks and Benefits 39 where your glucose is now, where it has been, where it’s heading, and how fast it’s changing. Understanding your trends allows you to take proactive action, helping you 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).

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.
 Dexcom G5 Mobile System User Guide What Is the Dexcom G5 Mobile CGM System? 45 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: dexcom.com/compatibility. 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.
 Dexcom G5 Mobile System User Guide What Is the Dexcom G5 Mobile CGM System? 46 There are a number of Alerts, but only one Alarm: when your glucose level dips below 55 mg/dL. Some customization options are available and are part of the setup process for the receiver and smart device. In Chapter 11, you can learn more about the Alarm and Alerts feature. Viewing Your Glucose Values The G5 Mobile allows you to see your last 1-3-6-12-24 hours of your sensor glucose readings. On the receiver, from the home screen, tap graph to view. On a smart device, hold upright in portrait mode to see the most recent three hours; turn sideways to landscape mode to view your glucose levels over the last 1-3-6-12-24 hours.

Now that you are familiar with the sensor and transmitter, let’s review the receiver. 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 and can get damaged if 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.

Use your smart device! Battery died on your smart device? Smart device memory full? Your receiver has you covered! With the exception of Dexcom Share, the primary difference between the two monitoring systems is not the data itself, but how it’s presented. The next section walks you through the initial setup for the app. To set up the receiver, go to Chapter 5.5. If you want to use both the G5 Mobile app and the receiver, you need to set up each individually. Once you have completed the initial setup, you’re one step closer to beginning your sensor session! 5.4 G5 Mobile App Before starting your first sensor session, pick the smart device you want to use. As mentioned in the previous chapter, you can use the receiver with one smart device during a session; however, you can’t use multiple smart devices during the same session.  While your smart device can have the app installed, part of your initial setup is entering the transmitter’s serial number (SN). If by accident you enter the SN
 Dexcom G5 Mobile System User Guide Set up Your Display Devices 59 into more than one smart device, the system warns you and you won’t be able to complete the setup process. Suggested Smart Device Settings Bluetooth is designed for wireless communication between devices (unlike Wi-Fi®, which wirelessly connects devices to the Internet). Your transmitter communicates to your app via Bluetooth® Smart! Before beginning, make sure your smart device’s Bluetooth is available and turned on. Refer to your smart device’s user guide if you have questions on how to change your smart device settings. • While checking your Bluetooth settings, check to see Silent and Do Not Disturb are off. Your app does not override these settings; if you have them on, you will miss Alarm/Alerts • After verifying all your settings are correct, there is one more thing to check. Make sure your smart device’s Volume is loud enough for you to hear any Alarm/Alerts • Make sure your smart device settings allow your Alarm/Alerts to always show on your lock screen • For information on how to set the above settings, see your smart device’s user guide. Once you have verified your smart device’s settings are right, the next step is installing the G5 Mobile app • The app needs to be open and running in the background. This may drain your smart device’s battery; make sure you check its battery is charged • Don’t change your smart device’s time because it can make the time on the trend screen wrong and the app may stop displaying data If your smart device is broken or lost, use receiver until it’s fixed or replaced.

Now that you have completed setting up your app and/or the receiver, your next step is starting a sensor session.  No matter what monitoring method you choose, starting a sensor session is the same:
 Dexcom G5 Mobile System User Guide Set up Your Display Devices 77 1. Inserting the sensor. 2. Attaching the transmitter. 3. Pairing the transmitter to your device. 4. Two-hour sensor warmup. 5. Initial calibrations.
 Dexcom G5 Mobile System User Guide Calibration 78 Chapter 6 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: click Support 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 Bluetooth needs to pair with the transmitter, 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. After this chapter you will be able to: • Identify sensor applicator features
 Dexcom G5 Mobile System User Guide Calibration 79 • Properly prepare for sensor insertion  • Choose the best location to insert your sensor • Correctly insert your sensor • Prepare transmitter for placement  • Correctly attach transmitter to sensor • Outline what happens during the sensor warmup • Identify countdown icon 6.2 Safety Statements Following are some important Warnings and Precautions to review; we want to make sure you and the system are safe before starting a sensor session.  Warning Don’t: If a sensor breaks under the skin with no portion visible above the skin, don’t remove it. Do: Seek professional medical help if you have symptoms of infection or inflammation (for example,, redness, swelling or pain) at the insertion site. If your sensor breaks under your skin, report it to Technical Support (available 24/7) as soon as possible: Email: TechSupport@dexcom.com Toll free: 1.888.738.3646 Toll call: 1.858.200.0200 Why: Sensors may fracture on rare occasions. MRI with broken wire For patients undergoing an MRI with a retained wire broken off from a G5 sensor, in vitro MRI testing did not detect any safety hazards. There was no significant migration or heating of the wire, and imaging artifacts were limited to the area around the wire.
 Dexcom G5 Mobile System User Guide Calibration 80  Warning Don’t: Insert the sensor component of the G5 Mobile in a site other than the belly/abdomen (ages 2 years and older) or the upper buttocks (ages 2 to 17 years).  Why: The placement and insertion of the G5 Mobile sensor is not approved for other sites. Consequences: The system has not been tested in other areas and may not work properly if inserted in other areas.  Warning Do: Store sensor between 36° F-77° F during its shelf life. Why: Storing the sensor incorrectly might cause the sensor glucose readings to be inaccurate. Never store sensors in the freezer. Consequences: If stored outside of 36° F-77° F, your sensor glucose readings may not be accurate, resulting in you missing a severe low or high glucose event.  Warning Don’t: Never use the G5 Mobile sensor glucose readings for treatment decisions. Do: Only use BG values from your BG meter for treatment decisions (for example, how much insulin to take). Why: Since they measure your glucose from different body fluids, sensor glucose readings can be different from your meter’s BG values. Consequences: Using sensor glucose readings for treatment decisions could result in you missing a severe low or high event.
 Dexcom G5 Mobile System User Guide Calibration 81  Precaution Do: Select sensor insertion site with care. 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 Why: Insertion in these areas might affect sensor performance.  Consequences: Inaccurate sensor glucose readings may result in you missing a severe low or high event.   Precaution Do: Check sensor package before opening. Why: Make sure the sterile sensor pack has not been damaged or previously opened. If opened or damaged, sensor may be unsterile.  Consequences: Using an unsterile sensor may cause an infection.  Precaution Don’t: Never get dirt or water in the receiver’s USB port or submerge in water. Why: If dirt or water gets into the USB port, the receiver could become damaged and stop displaying readings or providing Alerts.  Consequences: You might miss a severe low or high glucose event. 6.3 Prepping for Sensor Insertion Before inserting a sensor, make sure you have everything you need. Some items are included in the G5 Mobile’s packages, others are not.
 Dexcom G5 Mobile System User Guide Calibration 82 Included in Your G5 Mobile Packages For sensor insertion, you need the sensor and transmitter.

Your test strips Before starting, check your BG meter; make sure it’s in good working order following manufacturer’s directions and the meter’s date and time match your display device’s date and time. Make sure test strips haven’t expired and work with your meter.  Before removing the sensor applicator out of its sterile pack, determine the best place to insert your sensor. 6.4 Choosing Your Insertion Site
 Dexcom G5 Mobile System User Guide Calibration 85 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. Insertion Sites   Location Where it is  Front of body (belly area) for ages 2 years and above.  If user is between the ages of 2 years and 17: Back of body (Upper buttocks) Do: • Remove the sensor and applicator from its sterile pack only at time of use • Place at least 3 inches from your insulin pump infusion set or injection site
 Dexcom G5 Mobile System User Guide Calibration 86 • If needed, shave the area so adhesive patch sticks securely  • Make sure area is clean and free of lotions, perfumes, medications Don’t: • 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. See Step 3 in the next table for directions. NOTE: Contact your healthcare professional for specific questions regarding the use of medical tape, barrier wipes, and/or other adhesives as it relates to your use of Dexcom CGM. 6.5 Inserting Your Sensor You’ve collected all of the needed items to begin a sensor session, viewed the tutorials, reviewed the sensor applicator, and prepped the sensor pod site.

If not completely snapped in, you may have a bad connection and it won’t be water tight. 6   Hold sensor pod sides with one hand. Twist latch away from your body with other hand. Remove latch. Don’t remove transmitter while sensor pod is attached to skin. 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. 6.7 Loose Sensor Pod The sensor pod should stay on your skin using its own adhesive.  If the patch peels up, use medical tape (such as Blenderm™, Tegaderm™, Smith & Nephew IV3000®, 3M™ tape) for extra support.  • Tape over white adhesive patch on all sides for even support
 Dexcom G5 Mobile System User Guide Calibration 94 • 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. Dexcom App: Starting a Session Step What you see What you do

 Dexcom G5 Mobile System User Guide Calibration 101 Chapter 7 Let’s G5! The Basics: Calibration 7.1 Introduction In the previous chapter, you learned how to insert your sensor, attach your transmitter, and start a new sensor session. You’re now ready to begin your last step before getting your sensor glucose readings: Calibration. This chapter reviews not just your initial calibration, but also update calibrations required throughout your sensor session.  After this chapter, you will be able to: • Calibration overview o Define calibration o Explain the importance of calibration o Identify steps to ensure a successful calibration  • Recognize steps in taking accurate BG measurement o Identify the correct BG site for calibrations o Prepare finger for fingerstick measurement • Determine if you should/should not calibrate o Recognize when you can enter a fingerstick measurement for calibration o Recognize when you shouldn’t enter the a fingerstick measurement for calibration o Determine if you need to calibrate outside of the normal calibration requirements • Initiate startup calibration • Perform update calibrations
 Dexcom G5 Mobile System User Guide Calibration 102 • Correctly enter your fingerstick measurement o App o Receiver • Identify calibration errors 7.2 Safety Statements Contraindication Don’t: Never take any medications containing acetaminophen during your sensor session. Why: Taking medications with acetaminophen (such as Tylenol or Excedrin Extra Strength) while wearing your sensor may falsely raise sensor glucose readings. Level of sensor inaccuracy: 1. Depends on amount of acetaminophen active in your body. 2. May be different for each person.  Consequences: Without correct readings you might miss a severe low glucose event.  Warning Don’t: Never use the G5 Mobile sensor glucose readings for treatment decisions. Do: Only use BG values from your BG meter for treatment decisions (for example, how much insulin to take). Why: Since they measure your glucose from different body fluids, sensor glucose readings can be different from your meter’s BG values. Consequences: Using sensor glucose readings for treatment decisions could result in you missing a severe low or high glucose event.
 Dexcom G5 Mobile System User Guide Calibration 103 Warning Do: Calibrate at least once every 12 hours. Why: Calibrating less often than every 12 hours might cause inaccurate sensor glucose readings. Consequences: Missing severe low (hypoglycemia) or high (hyperglycemia) Alarm or Alerts.  Precaution Do: Look at trend arrows before calibrating. Trend arrows help you determine if you can calibrate now or should wait. Don’t: Never calibrate if your BG is changing at a significant rate, typically more than 2 mg/dL per minute. Never 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 Why: Calibrating during significant rise/fall of BG may affect accuracy of sensor glucose readings.  Consequences: You may miss a severe low or high glucose event.
 Dexcom G5 Mobile System User Guide Calibration 104 Precaution Do: Enter the exact BG value displayed on your BG meter within five minutes of a carefully performed fingerstick measurement. Why: Entering the wrong BG values, or waiting more than five minutes before entry, might affect sensor accuracy.  Consequences: You may miss a severe low or high glucose event.   Precaution Do: Only use fingerstick measurements from your BG meter for calibration. Don’t: Never use alternative site BG values such as blood from palms, forearms, etc. Why: Alternative site BG values are different from a fingerstick BG value and may not reflect most recent BG value.  Consequences: You may miss a severe low or high glucose event. 7.3 Calibration Overview What Is a Calibration? As you learned earlier, the sensor glucose readings come from measuring the glucose fluids found between your cells (interstitial fluids). Although blood and interstitial fluids are similar, sensor glucose readings can be different between your fingerstick and your CGM. Calibration provides a comparison, or measurement, between your meter’s fingerstick measurement and the sensor’s glucose readings, allowing alignment between the sensor and meter.  Your BG meter “teaches” the sensor your glucose values through calibration. Just like a clock can need adjusting—calibrations allow your CGM to adjust to your body. Why Is Calibrating Important?
 Dexcom G5 Mobile System User Guide Calibration 105 Calibrations are a must to make sure the CGM system is performing at its best. By calibrating when the system notifies you that a calibration is due, the G5 Mobile uses your meter’s BG value to make sure the sensor glucose readings remain accurate throughout your session. How Do I Calibrate? Take a fingerstick measurement from your meter, and simply enter the meter’s BG value into one display device. This chapter lets you know what precautions you need to take before taking your BG meter value, then entering your data. Up to now, you needed to enter information such as Alerts, transmitter SN, etc., separately for the receiver and smart device. Calibration is different. You only need to enter calibrations into one display device. Don’t enter your BG values into both devices; enter into either your app or the receiver. If you enter your meter’s BG value into your receiver, it takes about five minutes for your sensor glucose readings to begin. In approximately ten minutes, you can view the readings in the other display device. How Often Do I Calibrate? There are three primary “must do” calibration events, each with its own prompts: 1. Two initial calibrations once your warmup session is complete. 2. Update calibrations done twice daily, once every 12 hours. 3. When you’re prompted. If you receive a calibration prompt outside of your scheduled calibration schedule, either the system doesn’t accept your most recent calibration or your meter’s BG value is very different from the sensor’s glucose reading. Don’t worry about keeping track of the time between calibrations, the system will prompt you when you are ready for another.  Now that you have an overview of calibration, let’s review some contraindications, warnings, and precautions you need to know and follow before you calibrate.
 Dexcom G5 Mobile System User Guide Calibration 106 7.4 When to Calibrate Calibrating on a regular schedule aligns your sensor glucose readings with your meter’s BG values. Without calibrations, your sensor may be inaccurate, and as a result, so will your display device’s sensor glucose readings, Alerts, and prompts, etc. There are important times when you must calibrate: 1. Initial or Startup Calibration: two hours after you insert your sensor. 2. 12 Hour Update: every 12 hours after two-hour startup calibration. 3. When system prompts you. With calibration prompts, your sensor and display device help you keep your calibration schedule on track. If your BG values are not between 40-400 mg/dL, the system won’t accept your calibration. Wait until you are within the 40-400 mg/dL range before entering your BG values. Initial Calibration: Sensor Startup Completed 1. At prompts (see next table) enter two back-to-back fingerstick measurements into just one device. 2. No need to do initial calibrations twice. a. Calibration data flows between the receiver and your app. b. Ten minute reporting delay between devices. 3. First update calibration is 12 hours after your initial calibration. Update Calibration Enter an update calibration every 12 hours after your initial calibration. Below is a sample calibration schedule. As you can see from the calendar’s BG meters, you: 1. Inserted your sensor and entered initial two calibrations on Monday at 10 AM.  2. Entered update calibrations at 10 PM that night.  3. For the rest of the seven-day sensor period, you enter update calibrations at 10 AM and 10 PM.
 Dexcom G5 Mobile System User Guide Calibration 107  Figure 5. Example Minimum Calibration Schedule During Seven Day Sensor Session Update calibrations are typically 12 hours since your last calibration; however, they can be sooner. As an example, if you know your next calibration is due at 10 PM, but you want to go to bed at 9 PM, you can do the calibration before bedtime, resetting the 12-hour count down. 1. Enter one fingerstick measurement at least every 12 hours. 2. Display devices provide calibration prompts. 3. You may be prompted to enter additional fingerstick measurements as needed. 7.5 Calibration Prompts Sensor Session Startup Calibration Prompts Once your two-hour sensor startup is complete, your display device tells you it’s time to enter the first of your two back-to-back startup calibrations. Once the system has accepted your BG values, your glucose readings begin. If you don’t enter your BG values right away, the system reminds you every 15 minutes. Remember, only use your BG meter for calibrations, and never enter values from your CGM.

 Dexcom G5 Mobile System User Guide Calibration 110 Once your startup calibration is done, your update calibration schedule begins. The steps to enter your update calibrations are the same as your initial calibration, including only entering values in one display device. The only difference is, with update calibrations, enter your BG meter value just once. The default BG value is your current reading if available or 120 mg/dL. Like the reminders you received with your initial calibration, if you don’t enter your BG meter values right away, the system prompts you every 15 minutes. Update Calibration Prompts Device What you see What it means What you do Smart Device: Lock Screen  Enter update calibration.

 Dexcom G5 Mobile System User Guide Calibration 111 In case you can’t look at your screen, both the smart device and receiver provide, with the exception of your regular 12-hour update calibration, beep/vibration prompts to let you know it’s time to calibrate or if there was a system calibration error. For more information on setting your sound/vibration prompts and how to clear them, please see Chapter 9. Smart Device Calibration prompts will alert you with a triple beep if your smart device is not on Silent or Do Not Disturb. Receiver The receiver alerts you with an initial vibration for calibration prompts. If not cleared, you receive a vibrate/beep every five minutes until confirmed.  7.6 Preparing for Calibration Your sensor depends on you to help make its sensor glucose readings accurate. If you don’t prepare properly for the calibration, your sensor may not provide you with the most accurate sensor glucose readings.  Nine Steps to Successful Calibration: Do: 1. Wash and dry your hands before taking a fingerstick measurement. 2. Always use the same meter you routinely use to measure your BG.  a. BG meter and strip accuracy vary between meter brands. b. Switching within a session might cause sensor glucose readings to be less accurate. 3. Follow meter’s instructions exactly when taking your fingerstick measurement. 4. Verify test strips are current and, if required, coded correctly with meter. 5. Check: Is Bluetooth on? 6. Use fingerstick BG values only. a. Other sites are not as accurate. b. Must enter within five minutes of taking BG meter value.
 Dexcom G5 Mobile System User Guide Calibration 112 c. Enter exact BG value from your meter for each calibration. Don’t: 1. Don’t take acetaminophen-containing medication during your session (for example, Tylenol). a. See your healthcare professional to better understand how long acetaminophen is active in your body. 2. Don’t calibrate if your BG values are under 40 mg/dL or over 400 mg/dL. a. If BG value is outside of this range, receiver doesn’t understand these values and won’t calibrate. i. You must wait until your BG is in the range to calibrate. 3. Don’t calibrate if trend arrows are going straight up or down. a. Glucose is changing too quickly for an accurate calibration. Be safe—if BG is low, first treat low blood sugar, and then calibrate.  7.7 Ready? Set? Calibrate! You’ve followed the eight steps above, have a valid BG value from your meter, and your display device keeps alerting you: Calibrate! Calibrate! Calibrate! Remember: You don’t have to take a fingerstick measurement for each display device when calibrating; once you enter the reading into one, data is pushed to the other within ten minutes. Next are steps to enter your calibrations using the app, followed by the steps for entering your calibrations into the receiver.

 Dexcom G5 Mobile System User Guide Calibration 120 In the next chapter, you’ll learn how to end a typical seven-day sensor session, what to do if you need to end your sensor session early, along with removing the transmitter and determining if you need to replace it.
 Dexcom G5 Mobile System User Guide Ending Your Sensor Session and Transmitter Session 121 Chapter 8 Let’s G5! The Basics: Ending Your Sensor Session and Transmitter Session 8.1 Introduction G5 Mobile sensor sessions last seven days. This chapter reviews what you should expect when your session is about to expire and removing the sensor and transmitter. It also covers how to determine if you need to end your session early.  After this chapter, you will be able to: • Identify replace sensor prompts at the end of a seven-day sensor session • Recognize when you have to end a sensor session early • Successfully end a sensor session early o Identify how you can prevent sensor session failures • Remove your sensor pod with transmitter attached • Separate transmitter from sensor pod • Determine if transmitter can be used for another sensor session • Pair a new transmitter  To keep up with your glucose trends, it’s important to begin a new sensor session as quickly as possible. After a sensor session ends, the sensor stops taking your sensor glucose readings. You won’t get your trends, nor will you get any Alarm or Alerts. Before stopping a session and removing the sensor pod and transmitter, review the following safety statements to make sure you don’t harm yourself. 8.2 Safety Statements Warning Don’t: If a sensor breaks under the skin with no portion visible above the skin, don’t remove it. Don’t ignore sensor fractures. Do: Seek professional medical help if you have symptoms of infection or inflammation (for example, redness, swelling or pain) at the insertion site. If your sensor breaks under your skin, report it to Technical Support (available 24/7) as soon as possible: Email: TechSupport@dexcom.com Toll free: 1.888.738.3646 Toll call: 1.858.200.0200 Why: Sensors may fracture on rare occasions. MRI with broken wire For patients undergoing an MRI with a retained wire broken off from a G5 sensor, in-vitro MRI testing did not detect any safety hazards. There was no significant migration or heating of the wire and imaging artifacts were limited to the area around the wire.   Precaution Do: Keep Transmitter until it’s battery life has ended. Why: Transmitter is reusable. • Use for multiple sessions
 Dexcom G5 Mobile System User Guide Ending Your Sensor Session and Transmitter Session 122 8.3 Ending Your Sensor Session There are different ways your session might end. The most common is your sensor’s typical seven-day time frame ended. The second is ending the sensor session early. You may end a session early based on a personal decision, or on rare occasions, the receiver or app detects sensor issues and prompts you to end the session. Let’s review ending a normal session first; later in this chapter we’ll review the prompts for ending the session early.

Remember, if your smart device is on Silent or Do Not Disturb, you won’t get any sound prompts. For more information on setting your sound/vibration prompts, please see Chapter 9. Smart Device Your smart device prompts you with a triple beep. If not cleared, you receive the triple beep twice, five minutes apart. Receiver The receiver alerts you with an initial vibration prompt. If not cleared, you receive a vibrate/beep twice, five minutes apart. Once a sensor session has expired, you are ready to start your new session! If you’re not sure what to do, the app will provide instructions, or you can refer to the Getting Started Guide, online tutorials, or go to Chapter 6 in the user guide.  Ending Your Sensor Session Early For personal reasons, you may want to force quit a sensor session early (for example, you’re getting an MRI and need to remove sensor pod).  Or, occasionally, the app or receiver may detect something is wrong with your sensor and let you know it’s stopping the current session. This may be caused by a number of reasons: 1. Unresolved calibration issues. 2. Error symbol does not go away. 3. Wait symbol does not go away. 4. Sensor is coming out of the body (for example, the adhesive is peeling off). You’ll receive error prompts leading to a new sensor session. If you see error prompts, before stopping a sensor session early, always contact Technical Support (available 24/7) at: • TechSupport@dexcom.com • Toll free: 1.888.738.3646 • Toll call: 1.858.200.0200 When your display device has system errors, you may not receive any sensor glucose readings and you should not calibrate.

 Dexcom G5 Mobile System User Guide Ending Your Sensor Session and Transmitter Session 127 The G5 Mobile knows when a typical seven-day sensor session is over, automatically ending the session in each display device. However, if you need to end the session early, you need to let the system know by manually stopping the sensor session. While the end result is the same (ending a sensor session), the steps differ between the app and receiver. If you’re using both, no need to stop the sensor session in each: the other display will see the session has stopped. Let’s first look at how to end a sensor session in the app, then the receiver. App: Ending a Sensor Session Early Step What you see What it means What you do 1   Access Main Menu. Tap Main Menu icon. 2   Ends sensor session.

Temporarily Shut Down Receiver  To save on its battery, you can temporarily shut down the receiver. When shut down, your receiver and transmitter no longer communicate and you will not get any Alarm or Alerts although your sensor session remains active. Shutting down the receiver does not extend your sensor session past the seven days; it only stops the receiver from communicating with the transmitter. Your sensor session will stop seven days after you started the session.   Receiver: Temporary Shutdown
 Dexcom G5 Mobile System User Guide Ending Your Sensor Session and Transmitter Session 129  Step What you see What it means What you do 1   Go to Main Menu. Tap Menu. 2   Turns off receiver. Tap Shutdown. 3   Confirms you want to shut down. Shuts down receiver. Tap OK.  Press power button for two seconds to turn the receiver back on. It may take up to 20 seconds for the receiver to turn on.  Preventing Sensor Failures Sensor failures can happen when your display device doesn’t receive your sensor’s glucose readings. While it is rare to have a sensor failure, there are preventative steps you can take.  Help prevent sensor failures by checking: 1. Sensor hasn’t expired. 2. Transmitter is snapped securely in sensor pod. 3. Sensor pod isn’t dislodged or adhesive isn’t peeling. 4. Nothing is rubbing against sensor pod (for example, seat belts, etc.). 5. You selected a good insertion site (see Chapter 6). 6. Insertion site is clean and dry before sensor insertion. The app and receiver are ready for a new session! However before you can start a new sensor session, you need to end the current sensor session, and remove the old sensor and transmitter. 8.4 Remove Sensor Pod and Transmitter Remove Sensor Pod Think of the transmitter as being part of the sensor pod. Do not remove the transmitter before removing the sensor pod from your body. To remove the sensor pod: 1. Gently peel sensor pod adhesive patch from skin. a. Sensor wire comes out with sensor pod. 2. Separate the transmitter from the sensor pod. 3. Discard the sensor pod following your local waste management regulations for disposing of blood-contacting parts (sensor and applicator).
 Dexcom G5 Mobile System User Guide Ending Your Sensor Session and Transmitter Session 130 Remove Transmitter From Sensor Pod Remember that the transmitter is reusable—do not throw away. It lasts 90 days and can be used in multiple sensor sessions. Keep using it until the system notifies you the transmitter battery is about to expire. Before reusing the transmitter in your new sensor session, remove it from the old sensor pod.  You can detach transmitter two ways: 1. Use safety lock (see With Safety Lock table). You removed this from the applicator barrel at the beginning of the session.  2. Manually spread out tabs holding transmitter in sensor pod (see Without Safety Lock table). With Safety Lock Step Picture What you do 1   Grasp end of adhesive patch. Peel adhesive patch up and away from your body to remove sensor pod and transmitter. 2   Put sensor pod on flat surface. 3   Place safety latch’s jagged edge: Over transmitter’s wide edge  In between open slots on sensor pod’s sides  4   Lift up safety latch.  After removing your sensor, and taking the transmitter out of the sensor pod, you’re ready to begin a new sensor session. The transmitter’s battery is good up to three months. If you haven’t received your final seven-day transmitter battery life warning, you can reuse the transmitter for your next session.  Remember: 1. Never use same spot repeatedly for sensor insertion. 2. Never use same site for 2 sensor sessions in a row. Without Safety Lock Step Picture What you do 1   Grasp end of adhesive patch. Peel adhesive patch up and away from your body to remove sensor pod and transmitter. 2   Put sensor pod on flat surface.
 Dexcom G5 Mobile System User Guide Ending Your Sensor Session and Transmitter Session 131 Step Picture What you do 3    Grasp sensor pod’s wide end with two hands and place fingers in sides’ open slots.  4   Pull tabs away from transmitter. 8.5 End of Transmitter Battery How do you know if your transmitter’s battery will last through your next session? System messages help you determine if your transmitter’s battery will last through your next seven-day session. Starting at three weeks prior to the end of its battery life, the messages countdown the transmitter’s battery until it has only seven days. If the transmitter battery has seven days or less remaining, you won’t be able to start a new session. Transmitter Battery Messages Device What you see What it means Smart Device: Lock Screen  Transmitter battery will expire in three weeks. Order a new transmitter.

Receiver The receiver alerts you with an initial vibration prompt. If not cleared, you receive a vibrate/beep twice, five minutes apart.   8.6 Pair New Transmitter After the transmitter battery has died and before starting a new sensor session, you need to pair your new transmitter with your display device(s). In Chapter 5 you learned how to pair your transmitter using the set up wizard. But how do you pair a new transmitter once your display device is set up?  Part of pairing the transmitter is entering it’s SN into your display device, inserting the sensor, and attaching the transmitter. After the transmitter and display device are paired,start a new sensor session.   App Step What you see What you do 1    Tap Menu 2   Tap Settings 3     Tap Transmitter

 Dexcom G5 Mobile System User Guide Home Screen, Rate of Change Arrows, and Errors 140 Chapter 9 Next Steps - Getting the Most out of Your G5 Mobile: Home Screen, Rate of Change Arrows, and Errors 9.1 Introduction to Home Screens In the previous chapter, you learned about calibrations: why they are important and how to do them. Within five minutes of entering your two initial calibrations your sensor glucose readings begin! In this chapter, you’ll learn three things. First, reading the home screen, second, identifying your sensor glucose readings and trends: What do they mean? What’s the best way to use trend information? And third, what you do if you aren’t getting your sensor glucose readings. The purpose of this chapter isn’t to tell you how to react to your trends, but to help you recognize where your glucose was and where it’s going. Your healthcare professional can help you with your questions on what actions to take based on your glucose trends.  After this chapter, you’ll be able to: • Recognize home screen icons • Locate sensor glucose reading • Explain sensor glucose target range • Recognize the importance of gray, yellow, and red colors • Identify Low/High Glucose Alert levels on your trend graph • Describe when you receive a High or Low sensor glucose reading • Change trend graph views  • Cite differences between rate of change arrows • Recognize error messages 9.2 Safety Statements
 Dexcom G5 Mobile System User Guide Home Screen, Rate of Change Arrows, and Errors 141 Take a moment and read the safety statements. If not followed, your sensor glucose readings and trends may be less accurate, and you may miss important High or Low Glucose Alerts. Contraindication Don’t: Never take any medications containing acetaminophen during your sensor session. Why: Taking medications with acetaminophen (such as Tylenol or Excedrin Extra Strength) while wearing sensor may falsely raise sensor glucose readings. Level of inaccuracy depends on: • Amount of acetaminophen active in your body. • May be different for each person. Consequences: Without correct readings you might miss a severe low event.   Warning Don’t: Never use the G5 Mobile sensor glucose readings for treatment decisions. Do: Only use BG values from your BG meter for treatment decisions (for example, how much insulin to take). Why: Since they measure your glucose from different body fluids, sensor glucose readings can be different from your meter’s BG values. Consequences: Using sensor glucose readings for treatment decisions could result in you missing a severe low or high glucose event.
 Dexcom G5 Mobile System User Guide Home Screen, Rate of Change Arrows, and Errors 142 Warning Don’t: Never ignore symptoms of high and low glucose. Do: Measure your BG with a fingerstick measurement if sensor glucose readings don’t match your symptoms. Why: Your sensor glucose readings may not be accurately reading your glucose. Consequences: Using sensor glucose readings for treatment decisions could result in having severe low (hypoglycemia) or high (hyperglycemia) events.  Precaution Do: After connecting any accessories, make sure that the smart device settings allow you to continue receiving Alarm or Alerts on the smart device. Why: Using an accessory device (like a smart watch) might override your smart device sounds. Consequences: Alarm or Alerts might vibrate or be heard on the accessory instead of your smart device causing you to miss severe low or high glucose Alarm or Alerts.  9.3 Overview of Home Screen Regardless of your display device, the home screen shows your current sensor glucose value, glucose trend, rate of change arrow and CGM system status. While the screen does look different between the receiver, smart device, Apple Today View, and Apple Watch, the information is the same.  The G5 Mobile app has two ways to view data based on how you hold your smart device:
 Dexcom G5 Mobile System User Guide Home Screen, Rate of Change Arrows, and Errors 143 1. Vertically in portrait: 3-hour trend information with task bar. 2.

 Dexcom G5 Mobile System User Guide Home Screen, Rate of Change Arrows, and Errors 163   9.4 Rate of Change Arrows Not sure of how your sensor glucose readings are trending?  Rate of change arrows show the speed and direction of your glucose trends based on the last several sensor glucose readings. Arrows and the trend graph help you know when to take action before you are too high or too low.  However, before doing anything, think about your most recent insulin dosing, food intake, overall trend graph, and current BG value. Don’t overreact to the arrows. Remember the arrows don’t reflect your latest reading: they reflect a combination of recent readings.   Rate of Change Arrows Change Arrows What your glucose is doing   Steady Changing: • Less than 1 mg/dL each minute • Up to 15 mg/dL in 15 minutes      Slowly Rising or Falling Changing: • 1-2 mg/dL each minute • Up to 30 mg/dL in 15 minutes      Rising or Falling Changing: • 2-3 mg/dL each minute  • Up to 45 mg/dL in 15 minutes

By now you have a pretty good understanding how your trends look on the different display devices, but did you know what you do can affect your trends and patterns? It’s important to track actions or well-being, to better understand that what you do or how you feel can change your trends.  In the next chapter, you will learn how to enter Events into your G5 Mobile.
 Dexcom G5 Mobile System User Guide Daily Events Affect Your Glucose Trends and Patterns 171 Chapter 10 Next Steps - Getting the Most out of Your G5 Mobile: Daily Events Affect Your Glucose Trends and Patterns 10.1 Introduction Your daily activities can impact your glucose trends and patterns. In the previous chapter, you learned how to read your glucose trend screens; in this chapter, you learn how to enter situations, or “Events”. By tracking Events, you can determine how certain actions or circumstances affect your glucose levels. After this chapter, you’ll be able to: • Define Event • Describe each Event • Create Events o App o Receiver • Recognize Event markers on the app o Describe how Event markers are different in portrait and landscape view • Describe how to view Events entered via your receiver • View Event markers on your smart device 10.2 What Is an Event? Did you take a walk after lunch today? Did you go to happy hour with your co-workers and have a beer? Are you feeling stressed? Did you catch your kid’s sniffles? How much insulin did you take for your dinner meal? These are all Events that can raise or lower your blood sugar.
 Dexcom G5 Mobile System User Guide Daily Events Affect Your Glucose Trends and Patterns 172 An Event is an action or situation affecting your glucose levels. With the G5 Mobile, you have the ability to enter your daily Events, helping you track their effect on your glucose trends. Once entered into the smart device or receiver, Events can be viewed in Dexcom reports. The reports help you review how each Event influenced your glucose trends. You can use the reports with your healthcare professional to create a game plan in managing your diabetes. Even though they differ on how to enter an Event and time, the app and receiver have the same Event categories and subcategories. Later in this chapter, you’ll learn how to enter Events in each device.  Event Categories There are four main Event categories: 1. Carbs 2. Insulin 3. Exercise 4. Health The fourth category, Health, has more options: • Illness • Stress • Feel High • Feel Low • Cycle • Alcohol The following table provides more detail on each type of Event.

As an example, you’re running late because of traffic (Stress) and quickly swing by a drive-thru to get lunch (Carbs of 85 grams).
 Dexcom G5 Mobile System User Guide Daily Events Affect Your Glucose Trends and Patterns 180 For your convenience (and safety!), no need to stop everything and enter your Events as they are happening. When you have a moment, you can enter your Events retroactively in your app or receiver.  Events are meant to be entered as individual occurrences: don’t enter daily totals, enter each Event separately. In the next section, you will learn how to enter Events, first in your smart device, then in your receiver. 10.3 Entering Events You probably will enter Events in the display device you use most often; however, you should know how to enter Events into each. First, let’s look at how to enter Events in a smart device, then in the receiver.  When using Dexcom Share, you can allow your Followers to see your Event entries. For more Dexcom Share information, please see Part 5. Enter Events: Smart Device In the G5 Mobile app, Events are just a tap away! The Event icon, a running man, is on the app’s home screen’s task bar in portrait mode (remember, you don’t have the task bar in landscape). Entering Events for the Carbs, Insulin, Exercise, and Health categories follows the same steps. If you can enter a Carbs Event, you can enter an Insulin Event. To enter Events, we’ll use the above scenario. The following table shows how to enter Carbs (drive-thru lunch) and Stress (traffic jam) Events.

In the next chapter, you will learn about your trend’s Alarm and Alerts helping you monitor your glucose levels. You’ll also learn how you know when your system loses its signal and stops communicating.
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 192 Chapter 11 Next Steps - Getting the Most out of Your G5 Mobile: Sensor Glucose Alarm and Alerts 11.1 Introduction Monitoring your glucose trends is critical in managing your diabetes. But what happens if you’re driving or at the movies and can’t, or don’t want to, keep looking at your display device? The G5 Mobile understands there are times when you can’t look at your receiver or smart device; however, you still need to know critical glucose trends or if you’re not getting your sensor glucose readings.  This chapter reviews the sensor glucose Alarm and Alerts based on your sensor glucose readings, allowing you to proactively manage your glucose trend levels and make sure your transmitter is communicating with your display device.  In the next chapter, you’ll learn how to customize the Alarm and Alerts.  After this chapter you will be able to: • Define an Alarm  • Define an Alert • Identify the different types of Alerts • Describe the difference between an Alarm and an Alert • Recognize different Alarm/Alert prompts and sounds • Determine if signal loss is preventing you from getting an Alarm or Alert • Describe recommended app settings  • Successfully clear an Alert o App o Receiver Your trending information is one of the greatest benefits of the G5 Mobile. It’s important to focus on your trends and rate of change arrows, rather than the exact number of your glucose reading.
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 193 11.2 Safety Statements The Alarm and Alerts were designed to keep you safe, helping you avoid severe lows and highs or missing your readings. The following safety statements help ensure you get your Alerts and Alarm.  Warning Do: Verify your smart device settings let you get Alarm and Alerts. To receive Alarm/Alerts you must: 1. Make sure G5 Mobile app Notifications are turned on in Settings menu. 2. Verify app hasn’t been shut down. 3. Adjust volume so you can hear sounds. 4. Turn Bluetooth on. 5. Turn off Do Not Disturb. 6. Keep G5 Mobile app running in the background. 7. Restart app after device is restarted. Why: Your app’s settings do not override phone settings. Consequences: Missing severe low or high glucose Alarm or Alerts.   Warning Don’t: Never assume the G5 Mobile’s Alarm/Alert vibrations are different from other vibrating apps. Do: Look at your smart device and check if vibration is a G5 Mobile Alarm or Alert. Why: Medical device apps don’t have special priority over your smart device’s features. You can’t determine if the vibration is coming from your G5 Mobile app or another app. Consequences: Missing severe low or high glucose Alarm or Alerts.
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 194 Warning Do: Disconnect headphones from your smart device when not in use. Why: If headphones are connected while not being used, you won’t hear an Alarm or Alert. Consequences: Missing severe low or high glucose Alarm or Alerts.  Precaution Don’t: Never prevent communication between transmitter and display devices. Do: Keep smart device and receiver within 20 feet of transmitter and away from obstructions. Why: If your transmitter and display device(s) are more than 20 feet apart or are separated by an obstruction, they might not communicate. Types of obstruction differ and not all types have been tested. Obstructions can include water, walls, metal, etc. Water (for example, when swimming, surfing, bathing, etc.) can severely limit communication range. Consequences: Missing severe low or high glucose Alarm or Alerts.  Precaution Do: Set smart device and receiver settings separately. Why: Settings are specific to each display device and don’t carry over to other devices. If you set up one device and then use another, you won’t get an Alarm or Alert. Consequences: Missing severe low or high glucose Alarm or Alerts.
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 195 Precaution Do: Verify smart device and receiver are turned on. Why: Neither the receiver nor smart device will generate sensor glucose readings, Alarm or Alerts if turned off. Consequences: Missing severe low or high glucose Alarm or Alerts. 11.3 Alarm and Alerts As part of managing your diabetes, you learned how to read your Trend screen and how to enter Events. In this chapter, you’ll learn how Alarm and Alerts can keep you safe from severe lows or highs. Depending on your display device, you can customize how you receive your Alarm or Alerts. What Is an Alarm? While there are a variety of Alerts, there is just one Alarm: the Urgent Low Glucose Alarm (Alarm), which is set at 55 mg/dL. The Alarm will repeat every 5 minutes until you clear the Alarm (see Chapter 12 on how to customize the sounds). If you clear the Alarm and your sensor glucose readings do not go over 55 mg/dL in the next 30 minutes, you get another Alarm. Unlike Alerts, the Urgent Low Glucose Alarm setting can’t be changed or turned off. Think of it as a safety net: your glucose level is dangerously low—pay attention now! What Are Alerts? An Alert is a message telling you your glucose trend levels need attention.  Low/High Glucose Alerts tell you when your sensor glucose readings are outside your target glucose ranges. Think of them as an FYI: You need to know what’s happening, Rising/Falling Alerts tell you your glucose levels are changing quickly. Their default settings are Off (see Chapter 12 on how to turn them on).
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 196 Alerts message you with vibrations (vibrations not available on all smart devices), visual prompts, sounds, or a combination of all three.  Unlike the Alarm, you can customize your different Alert’s target range (see Chapter 12).  During your initial setup, you establish your Low/High Glucose Alert levels. As mentioned before, this chapter is a review of the Alarm and Alerts, recommended smart device settings, and the receiver’s default Alert settings. Chapter 12 will show you how to change their settings: customize glucose levels prompts, how you are notified, and in some cases, how often you get notified. The following are the defaults. Default Alerts Low/High Glucose Alerts Your Low/High Glucose Alerts have the same color-coding as your Trend Graph screen:  1. Red: Glucose levels are below your low threshold. a. Default setting of 80 mg/dL. 2. Gray: Glucose levels are within your Low/High Glucose Alert levels. a. No Alerts. 3. Yellow: Glucose levels are above your high threshold. a. Default setting of 200 mg/dL. Rise Rate/Fall Rate/Repeat/Signal Loss Alerts Rise Rate and Fall Rate Alerts warn you when your glucose levels are changing rapidly, either down or up, and look similar to the rate of change arrows. Repeat Alerts let you know if your sensor glucose readings continue to be above or below your Alert levels. Glucose Level Alerts 1. Rise Rate a. Default setting is Off—No Alert.
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 197 b. Need to change settings to receive Rising Alert. 2. Fall Rate a. Default setting is Off—No Alert. b. Need to change settings to receive Falling Alert.  3. Repeat a. Default setting is Off—No Alert. b. Need to change settings to receive Repeat Alert. Signal Loss Alert Signal Loss tells you when you and the transmitter are too far from your display device or something is blocking your transmitter signal, causing you not to get sensor glucose readings. The default setting for Signal Loss is On. Now you have the basics for the G5 Mobile’s Alarm/Alerts features. Next, you will learn about each Alarm/Alert in more detail. 11.4 Alarm and Alerts Screens When you fall within an Alarm or Alert target range, your display device tells you. As mentioned in previous chapters, you won’t get any Alarm or Alerts within five minutes of calibration. Let’s first review how the information is presented visually across the devices. While the Alarm/Alerts prompts look different on the display devices, they reflect the same information. After prompts, we’ll separately review the vibration and audible Alarm/Alerts for app and receiver.  Urgent Low Glucose Alarm Device What you see What it means

The app can’t override your smart device settings:  • When your smart device is on Silent, you’ll still receive Alarm/Alerts visual prompts and messages, but not vibrations if you haven’t adjusted your smart device settings  • Some smart devices don’t have a Vibration feature, so you won’t get any vibration notifications • When your ringer’s volume is low, you may not hear an Alarm or Alert • When your smart device is in Do Not Disturb mode, you won’t receive any Alarm/Alerts. The G5 Mobile app can’t override the Do Not Disturb setting • If you don’t enable your G5 Mobile push Notifications settings during setup, you won’t get any Alarm/Alerts • Check in Settings under Notifications on how your Alarm/Alerts are prioritized For information on smart device settings, see your smart device’s instructions. If you are concerned about missing an Alarm or Alert (for example, due to smart device settings, app shutting off due to lack of storage, low smart device battery, etc.), bring your receiver with you. 11.6 Receiver: Default Beeps and Vibrations
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 206 The receiver’s Alarm/Alerts are vibrations and a beep, or a series of beeps, based on the Alarm or Alert. Beeps and vibrations are preprogrammed into the receiver, and unlike the smart device, the volume can’t be changed.  In Chapter 12 you’ll learn how to adjust the volume and intensity of your Alarm/Alerts. The following is a table of the receiver’s default beep and vibration patterns. If you clear the Alert’s initial vibration, you won’t get any beeps or sounds unless you’ve turned on the Repeat Alert. In the next section, you’ll learn how to clear the Alarm/Alerts. Urgent Low Glucose Alarm What you see Beeps and vibration  Initial Default Alert:  Vibrates 4 times. After 5 Minutes: Vibrates/beeps 4 times every 5 minutes until cleared or sensor glucose readings go above Alarm level. After 30 Minutes: After clearing Alarm, continues to notify if sensor glucose readings remain at or below Alarm level. Low/High Glucose Alerts What you see Beeps and vibration
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 207   Initial Default Alert: Vibrates 3 times. After 5 Minutes: Vibrates/beeps 3 times every 5 minutes until cleared or sensor glucose readings rises above Alert level.  Trend screen will continue to reflect Alert until sensor glucose readings go above Alert level.   Initial Default Alert: Vibrates 2 times. After 5 Minutes: Vibrates/beeps 2 times every 5 minutes until cleared.or sensor glucose readings go below Alert level. Trend screen will continue to reflect Alert until sensor glucose readings go below Alert level. Rise Rate/Fall Rate Alerts What you see Beeps and vibration
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 208   Initial Default Alert: None/Off. After Setting Change: Vibrates 2 times, 2 sounds. After 5 Minutes: Vibrates/beeps 2 times every 5 minutes until cleared or sensor glucose reading rises rate drops below Alert level.   Initial Default Alert: None/Off. After Setting Change: Vibrates 3 times. After 5 Minutes: Vibrates/beeps 3 times every 5 minutes until cleared or sensor glucose reading fall rate rises above Alert level.
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 209 Low Repeat/High Repeat What you see Beeps and vibration  Initial Default Alert: None/Off. After Setting Change: Vibrates 3 times. After 5 Minutes: Vibrates/beeps 3 times every 5 minutes until cleared or sensor glucose reading rises above Alert level. Will re-alert if sensor glucose readings drop at or below 55 mg/dL.  Initial Default Alert: None/Off. After Setting Change: Vibrates 2 times. After 5 Minutes: Vibrates/beeps 2 times every 5 minutes until cleared or sensor glucose reading drops below Alert level. Signal Loss Alert What you see Beeps and vibration
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 210  Initial Default Alert: On. After Setting Change: Vibrates 1 time. After 5 Minutes: Vibrates/beeps 1 time every 5 minutes for a total of 6 times if not cleared. After 6 times it will not alert again. 11.7 Clearing Alarm/Alerts Alerts require you to acknowledge and clear them. How this is done depends on your display device. If using both display devices, you’ll need to clear each separately.  Due to its medical importance, the Alarm is more persistent than an Alert. Even after acknowledging and clearing an Alarm, if your sensor’s glucose readings remain at or below 55 mg/dL, an Alarm will sound every 30 minutes until readings are above 55 mg/dL. Clearing Your Smart Device Device What you see What it means Smart Device:  Lock Screen  Slide Alarm or Alert to access app.
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 211 Smart Device: In App  Tap OK to accept Alarm or Alert. Clearing Your Receiver What you see What you do  Tap OK. Once an Alert is cleared, you won’t receive the same Alert unless you hit the Alert’s target range again. Your Alarm will repeat even after clearing if your glucose levels do not return to your target range. Summary Now You Can: • Define an Alarm  • Define an Alert • Identify the different types of Alerts
 Dexcom G5 Mobile System User Guide Sensor Glucose Alarm and Alerts 212 • Describe the difference between an Alarm and an Alert • Recognize different Alarm/Alert prompts and sounds • Determine if signal loss is preventing you from getting an Alarm/Alert • Describe recommended app settings  • Successfully clear an Alert o App o Receiver What’s Next? Up to now, you have learned about the Alarm or Alert default settings. But what do you do if you want to decrease the High Glucose Alert setting, or you want to continue getting a Low Glucose Alert if your glucose levels don’t improve, even though you cleared the message? How do you make your Alarm/Alerts fit your needs?
 Dexcom G5 Mobile System User Guide On the Go With G5: Customizing Your Alarm and Alerts 213 Chapter 12 Next Steps - Getting the Most out of Your G5 Mobile: On the Go With G5: Customizing Your Alarm and Alerts 12.1 Introduction The receiver and app come with default glucose Alert level settings, but perhaps they don’t reflect the glucose level that works best for you.  Perhaps you’re in a meeting and can only clear an Alert, yet want to make sure your Alert repeats, or continues, until you’re able to take corrective measures. Maybe you’d like to get a Rising/Falling Glucose Alert, but their settings are off by default. How do you turn them on? In this chapter, you’ll learn how to personalize your Alarm and Alerts tones and glucose levels. After this chapter you will be able to:  • Customize your glucose trend Low/High Alerts prompts o App o Receiver • Adjust Alarm sound prompts • Set up other Alerts o Low/High Repeat  o Rise/Fall Alerts o Signal Loss Each display device has customization options; however, the setup flow is different. Before making any changes to your Alert levels, talk with your healthcare professional. First, let’s take a look at personalizing your app Alarm and Alerts, and then we’ll review the same process for the receiver. 12.2 Safety Statement
 Dexcom G5 Mobile System User Guide On the Go With G5: Customizing Your Alarm and Alerts 214 Warning Do: If using both receiver and app to get an Alarm or Alert, change settings in each display device. Why: Any changes to the G5 Mobile app will not carry over to the receiver. Consequences: Missing severe low or high Alarm or Alerts. 12.3 Changing App Alarm and Alerts App Screen Overview The Alerts Main Menu lists all customizable Alerts and their current settings. Part of your initial setup included setting your Low/High Glucose Alerts. In this chapter, you’ll learn how to change them.

 Dexcom G5 Mobile System User Guide On the Go With G5: Customizing Your Alarm and Alerts 226 12.4 Changing Receiver Alarm and Alerts You’ll notice a flow difference between the app and the receiver when personalizing your Alarm/Alerts. With the app, all Alert adjustments are made from one screen, whereas in the receiver, you make changes in different screens. Unlike the app, you change your receiver’s tones (known as sounds) in the Sounds menu. Sounds Sounds determine the sound and volume of your Alarm and Alerts. As mentioned in the previous chapter, the receiver uses a series of beeps/vibrations for an Alarm or Alert. The receiver doesn’t have the same variety of tones as the app; however, you can adjust their volume. While the receiver doesn’t have a silent mode, selecting Vibrate will replace audible beeps with quiet vibrations. The only exception is the Alarm: the Urgent Low Glucose Alarm can’t be turned off. Changes made in sounds are applied to all of the receiver’s Alarm/Alerts. If you choose Soft (see next table), all Alerts are in Soft mode. In Chapter 10, you learned how many beeps each Alarm/Alert has. Normal is the default setting for your receiver sounds. Attentive uses a rising or falling melody instead of beeps. The receiver first vibrates when sending you an Alarm or Alert. If you clear the Alarm/Alert at the first vibration, you won’t get any Alarm/Alert tones. If you would like to continue to get your Alarm or Alert after clearing, later in this chapter you’ll learn about setting up Repeat Alerts. HypoRepeat is very similar to the Normal sound, but keeps repeating the Urgent Low Glucose Alarm every 5 seconds until your sensor glucose value rises above 55 mg/dL or you confirm by tapping OK on your screen. The next table lists the different Sounds, starting with the quietest, working its way up to the loudest. Alarm/Alert Sounds

If you want the Urgent Low Glucose Alarm to repeat until your glucose levels are back above 55 mg/dL, turn on the Hypo Repeat option.  Alerts Menu The Alerts menu gives you options for personalizing your glucose level Alerts and turning on your Rising/Falling and Signal Loss Alerts.
 Dexcom G5 Mobile System User Guide On the Go With G5: Customizing Your Alarm and Alerts 230 Low and High Adjust your Low and High Glucose Alert levels (mg/dL) along with turning on and setting the time for the Repeat prompt. Rise and Fall Rates Your trend screen provides visual cues letting you know your sensor glucose readings are falling or rising rapidly.  Constantly looking at your screen may not be practical. You can customize your Rise and Fall Rate Alerts with vibrations or beeps letting you know when your glucose is rising or falling (2 mg/dL/min or 30 mg/dL up or down in 15 minutes) or rising or falling rapidly (3 or more mg/dL/min or 45 mg/dL or more up or down in 15 minutes). The default setting is Off for Repeat, Rise Rate, and Fall Rate. It’s important that you discuss your Alert settings with your healthcare professional. Signal Loss Signal Loss Alert tells you when your transmitter and receiver aren’t communicating. Set the Signal Loss Alert and get alerted if your sensor glucose readings have stopped due to a signal loss lasting anywhere from 20 to 200 minutes.  The default setting for Signal Loss is On.  Steps to Customize Receiver Alarm/Alerts Using the same example from changing your app Alerts, let’s change the receiver’s High Alert level from 200 mg/dL to 190 mg/dL, repeating every 60 minutes. Follow these same steps for turning on the Rise/Fall Rate Alerts and adjusting your Low Alerts.  Customizing Alerts: Receiver Step What you see What it means What you do

This chapter covers only the G5 Mobile. It doesn’t cover steps you need to take when traveling with your smart device. See your smart device’s instructions to learn how to travel with it. After this chapter, you will be able to: • Explain proper procedure if you prefer a full-body pat-down • Describe steps needed for a TSA officer to inspect G5 Mobile components • Identify when your display device(s) can be on during a flight • Contact TSA directly with your security questions 15.2 Safety Statements
 Dexcom G5 Mobile System User Guide On the Go With Dexcom G5 Mobile CGM System: Getting Through Security 256 Precaution Don’t: Never bring the G5 (sensor applicator, transmitter, and receiver) into an AIT body scanner (airport body scanner). Never put any part of the G5 in the baggage x-ray machine. Do: Request hand-wanding or full-body pat-down and visual inspection instead. Why: The system has not been tested in AIT scanners. Consequences: Missing severe low (hypoglycemia) or high (hyperglycemia) Alarm or Alerts. 15.3 Going Through Security Walk-Through Metal Detectors Transmitter and Sensor No worries about wearing your transmitter and sensor when going through security.  Go through walk-in metal detectors or, if you prefer, be hand-wanded without worrying about damaging your transmitter or sensor. If you’re concerned or uncomfortable about walking through the metal detector, the Transportation Security Administration (TSA) requests you tell the Security Officer you’re wearing a continuous glucose monitor and want a full-body pat-down with a visual inspection of your sensor and transmitter.  Let the Security Officer know the sensor can’t be removed because it’s inserted under the skin. X-Ray Machines Receiver, Extra Sensors Don’t put your G5 Mobile components through x-ray machines.
 Dexcom G5 Mobile System User Guide On the Go With Dexcom G5 Mobile CGM System: Getting Through Security 257 Before your screening process begins, ask the TSA Officer to perform a visual inspection of the receiver and your extra sensors. Place all G5 Mobile components in a separate bag before handing over to the Security Officer.  For other medical supplies, such as medications, meters, and strips, check manufacturer’s instructions or the TSA website. Body Scanners  Use of advanced imaging technology (AIT) body scanners, like millimeter wave scanners, has not been studied, and we therefore recommend hand-wanding or full-body pat-down and visual inspection in those situations.  In the Plane  To use your smart device, receiver, or both to get sensor glucose information while in the plane: • Smart device: When you switch to airplane mode, keep Bluetooth on • Receiver: Keep receiver on  Contact your airline for their policies.

 Dexcom G5 Mobile System User Guide Technical Information 263 Chapter 17 Everything Else G5: Technical Information 17.1 Device Performance Characteristics NOTE: We recommend that you review the information in this chapter with your healthcare professional to understand how well the G5 Mobile performs. The G5 Mobile (the system) uses a glucose sensor to continuously measure and monitor your glucose levels. The sensor is “calibrated” using a commercially available BG meter. Once calibrated, the system reports glucose readings up to every 5 minutes. The system was evaluated in clinical studies in which system readings were compared to BG values to assess its performance and how well the system readings compared to a laboratory test method that measures BG values. Additionally, subjects performed self-monitoring BG meter tests at home to assess the system performance in a real use environment. Although the performance characteristics of the system are presented in the following, there is no commonly accepted statistical approach for capturing performance of continuous glucose monitors (CGMs), such as the G5 Mobile. Clinical Study Overview The system performance was evaluated in four separate prospective clinical studies. Two studies included adults, and two studies included pediatrics. In the following sections and tables, the studies will be identified as follows: Adult Studies (18 years and older) Original Adult Study: the receiver included software version SW10050  Software 505 Adult Study: the receiver included software version SW10505  Pediatric Studies (2 to 17 years) Original Pediatric Study: the receiver included software version SW10050
 Dexcom G5 Mobile System User Guide Technical Information 264 Software 505 Pediatric Study: the receiver included software version SW10505 The G5 Mobile incorporates the algorithm from software version SW10505 and has a new software number. Overview of Adult Studies The system performance for adults was evaluated in two separate prospective clinical studies: Original Adult Study (software SW10050) and the Software 505 Adult Study (software SW10505). Differences between the studies include the number of subjects enrolled, the number of systems worn by each participant, the SMBG meter used, and the number of clinic days each subject participated in during the study. An overview of each study is provided here. The Original Adult Study enrolled 72 subjects, and the Software 505 Adult Study enrolled 51 subjects. All subjects had Type 1 or Type 2 diabetes mellitus, and required insulin or oral medication to manage their diabetes. In the Original Adult Study, 83% of subjects had Type 1 diabetes, and 17% of subjects had Type 2 diabetes. In the Software 505 Adult Study, 86% of subjects had Type 1 diabetes, and 14% of subjects had Type 2 diabetes. Both studies included subjects greater than 18 years of age.   Subjects in both studies used the system for seven days. In the Original Adult Study, thirty-six subjects each wore 2 sensors; in the Software 505 Adult Study, all subjects wore 1 sensor only. Throughout the 7-day wear period, the sensor was calibrated with an average of 2 fingersticks per day (approximately once every 12 hours). In the Original Adult Study, subjects used the LifeScan® OneTouch® Ultra®2 meter and in the Software 505 Adult Study, subjects used Bayer’s CONTOUR® NEXT USB meter. In the Original Adult Study, all subjects were evaluated in a controlled clinic environment on all three clinic days: Day 1, Day 4, and Day 7 of the 7-day wear period. In the Software 505 Adult Study, subjects were evaluated in one of the three clinic days so there are fewer data samples than in the Original Adult Study. While using the system in the clinic, subjects had their BG measured every 15 minutes with a reliable laboratory method, the Yellow Springs Instrument 2300 STAT Plus™ Glucose Analyzer. This instrument is referred to as the “YSI.” Readings from the system were reported every 5 minutes and paired with YSI values in order to characterize how well the
 Dexcom G5 Mobile System User Guide Technical Information 265 system readings agreed with laboratory standard BG results. The remainder of the study took place at home, and the system performance was also paired with the comparative meter results, referred to as the “SMBG.”  Overview of Pediatric Studies The system performance for children and adolescents was evaluated in two separate prospective clinical studies: the Original Pediatric Study (SW10050) and the Software 505 Pediatric Study (SW10505). Differences between the studies include the number of subjects enrolled, the number of systems worn by each participant, the SMBG meter used, the length of time subjects were evaluated in a controlled clinic environment and whether or not subjects ages 13-17 had their glucose levels intentionally manipulated during the study. An overview of each study is provided here.  The Original Pediatric Study enrolled 176 subjects, with 16% of subjects younger than 6-years old, and the Software 505 Pediatric Study enrolled 79 subjects, with 20% of subjects younger than 6-years old. All subjects had Type 1 or Type 2 diabetes mellitus and required insulin or oral medication to manage their diabetes. In the Original Pediatric Study, about 99% of subjects had Type 1 diabetes and 1% had Type 2 diabetes. In the Software 505 Pediatric Study, all subjects had Type 1 diabetes. Sensors were inserted in either the abdomen or upper buttocks.  Subjects in all studies used the system for seven days. In the Original Pediatric Study, all subjects wore 2 sensors; in the Software 505 Pediatric Study, all subjects wore 1 sensor only. Throughout the 7-day wear period, the sensors were calibrated with an average of 2 fingersticks per day (approximately once every 12 hours), using self-monitoring BG (SMBG) meter values. The Original Pediatric Study used the LifeScan® OneTouch® Verio® IQ meter; the Software 505 Pediatric Study used Bayer’s CONTOUR® NEXT USB meter. All subjects were evaluated in a controlled clinic environment on Day 1, Day 4 or Day 7 of the 7-day wear period. While using the system in the clinic, subjects provided at least two fingerstick measurements per hour, and subjects ages 6-17 also provided venous blood for comparison to a laboratory method, the Yellow Springs Instrument 2300 STAT Plus™ Glucose Analyzer. This instrument is referred to as the “YSI.” In the Original Pediatric Study,
 Dexcom G5 Mobile System User Guide Technical Information 266 subjects’ glucose levels were not intentionally manipulated during this study; in the Software 505 Pediatric Study, subjects ages 13-17 had their glucose levels intentionally manipulated during the clinic session. Readings from the system were reported every 5 minutes and paired with YSI values collected every 15 minutes in order to characterize how well the system readings agreed with laboratory standard BG results. The remainder of the study took place at home, and the system performance was also paired with the comparative meter results, referred to as the “SMBG.”

 Dexcom G5 Mobile System User Guide Technical Information 269 Agreement Relative to YSI Agreement between the system and BG values is characterized using paired system and YSI values. The system and YSI results were compared by pairing the YSI BG value to a system glucose reading that occurred immediately after the YSI was collected. The agreement of the system to BG value was assessed by calculating the percentage of system readings that were within 15%, 20%, 30% and greater than 40% of the YSI values. For readings less than or equal to 80 mg/dL the absolute difference in mg/dL between the two glucose results was calculated. For values greater than 80 mg/dL the absolute percent difference (%) from the YSI values was calculated. The percentages of total readings within 15 mg/dL or 15%, 20 mg/dL or 20%, 30 mg/dL or 30% or greater than 40 mg/dL or 40% are provided in Table 1-A and 1-B. The tables are categorized within CGM glucose ranges. When you see a CGM reading on your receiver, this table shows you how likely that reading matches your BG level (measured by YSI in the study). For example, in the SW10505 Adult Study (Table 1-A), the total number of data pairs considered in the analysis was 2263. Of these, 93% of the system readings fall within ± 20 mg/dL of the YSI BG values ≤ 80 mg/dL and within ± 20% of YSI BG values > 80 mg/dL.

Agreement When CGM Reads “LOW” or “HIGH” The system reports glucose readings between 40 and 400 mg/dL. When the system determines the glucose reading is below 40 mg/dL, it displays “LOW” in the receiver status box. When the system determines that the glucose level is above 400 mg/dL, it displays “HIGH” in the receiver Status Box. Because the system does not display glucose values below 40 mg/dL or above 400
 Dexcom G5 Mobile System User Guide Technical Information 272 mg/dL, the comparisons to the actual BG levels (as determined by the YSI analyzer) when CGM is classified as “LOW” or “HIGH” are included separately in Table 2-A and 2-B. The tables include the numbers and the cumulative percentages when YSI values were less than certain glucose levels (for “LOW”), and when YSI values were greater than certain glucose levels (for “HIGH”). For example, in the Software 505 Adult Study (Table 2-A), when the system displayed “LOW” (18 occasions), 100% (18 out of 18) of the YSI values were less than 80 mg/dL, and 94% (17 out of 18) of the YSI values were less than 70 mg/dL. When the system displayed “HIGH” (45 occasions), 100% (45 out of 45) of the YSI values were greater than 240 mg/dL, and 100% (45 out of 45) of the YSI values were greater than 280 mg/dL.

 Dexcom G5 Mobile System User Guide Technical Information 279 Accuracy Relative to YSI Accuracy between matched pairs was also estimated by calculating the percent difference between the system reading and the YSI value. For example, if the YSI value is 100 mg/dL and the system reading is 90 mg/dL, a 10% difference between the system and the YSI is reported. The system and YSI values were compared by pairing the system reading that fell immediately after the YSI value was collected. In the example above, the system reading is less than the YSI value, so the percent difference reading is negative. The mean percent difference is the average of all positive and negative percent differences between the two devices; it tells you if the system reads higher or lower on average than the YSI within each glucose range. Another estimate used to show the accuracy of the system is the absolute percent difference. The absolute percent difference tells you the percent difference or “distance” between the system and YSI values, but does not tell you whether the system is reading, on average, higher or lower than the YSI laboratory standard. The mean absolute percent difference is the average “distance” (regardless if positive or negative) between system readings and YSI values. Accuracy measures in differences for both the Original Adult and Software 505 Adult Studies are summarized in Table 4-A. Accuracy measures in differences for both the Original Pediatric and Software 505 Pediatric Studies are summarized in Table 4-B. Table 4-A and 4-B are categorized within CGM glucose ranges. For example, in the Software 505 Adult Study (Table 4-A), overall, on average, the system reads 2.5% different (Mean Percent Difference) than the reference and 9.0% absolute different (Mean Absolute Difference) than the reference values. The Median Percent Difference shows that half of the time the system reads 2.4% or less than the YSI BG values and the Median Absolute Percent Difference shows that half of the time the system reads about 7.0% or less than the YSI BG values.

The Low Glucose Alert Estimates of how well the adjustable Low Glucose Alert performs are presented in Table 5-A, 5-B and 5-C. Table 5-A represents the hypoglycemic alert evaluation within 15 minutes of the YSI value in the adult studies. Table 5-B represents the alert evaluation within 15 minutes of the YSI value for a subset of the pediatric population—subjects age 6 to 17 years who had YSI measurements every 15 minutes. Table 5-C represents the alert evaluation within 30 minutes of an SMBG reading for 2- to 5-year-old subjects in the pediatric studies. Hypoglycemia Alert Rate The Alert Rate shows how often the Alert is right or wrong. The True Alert Rate is the % of time the device alarmed when the BG level was at or below the Alert setting within 15 or 30 minutes before or after the device alarmed. The False Alert Rate is the % of time the device alarmed when the BG level was above the Alert setting within 15 or 30 minutes before or after the device alarmed. For example, if you set the Low Glucose Alert to 70 mg/dL and your Alarm sounds, how often can you expect your blood sugar to actually be low? In the Software 505 Adult Study (Table 5-A), when your Alarm sounds, you can expect your blood sugar to be below 70 mg/dL approximately 92% of the time and above 70 mg/dL approximately 8% of the time within the 15 minute period before or after your Alarm sounds.
 Dexcom G5 Mobile System User Guide Technical Information 284 Hypoglycemia Detection Rate The Detection Rate shows how often the device recognizes and alerts you to an episode of hypoglycemia or how often it misses such an event. The Hypoglycemia Detection Rate is the % of time the BG level was at or below the Alert setting and device alarmed within 15 or 30 minutes before or after the BG was at or below the Alert settings. The Hypoglycemia Missed Detection Rate is the % of time the BG was at or below the Alert setting, but the device did not Alarm within 15 or 30 minutes before or after the BG was at or below the Alert setting. For example, if you set the Low Glucose Alert to 70 mg/dL, how often will your Alarm alert you if your BG goes below 70 mg/dL? In the Software 505 Adult Study (Table 5-A), when your blood sugar goes below 70 mg/dL, you can expect your Alarm to sound 91% of the time and not to sound approximately 9% of time within the 15 minute period before or after your blood sugar goes below 70 mg/dL.

To demonstrate performance of the system over a 12-hour calibration period, systems were evaluated to verify that performance remains consistent over the 12-hour calibration period. Systems were evaluated in 2-hour increments after calibration. Performance was estimated at each 2-hour interval and stratified by glucose values by calculating the percentage of system readings within 15 mg/dL or 15%, 20 mg/dL or 20%, 30 mg/dL or 30%, 40 mg/dL or 40% and greater than 40 mg/dL or 40% of the YSI values in Table 7-A and 7-B.

 Dexcom G5 Mobile System User Guide Technical Information 295 Sensor Stability Relative to YSI Sensors can be worn for up to 7 days. Performance was estimated by calculating the percentage of system readings within 15 mg/dL or 15%, 20 mg/dL or 20%, 30 mg/dL or 30% , 40 mg/dL or 40% and greater than 40 mg/dL or 40% of the YSI values at the beginning (Day 1), middle (Day 4) and end (Day 7) of the system lifecycle. The average and median of the absolute percent differences are included in Table 8-A and 8-B showing consistent accuracy and sensor stability over the 7-day life of the sensor. Relative to SMBG (Pediatric Study) Performance was also estimated by calculating the percentage of system readings within various percentages of the SMBG values at each day of the sensor wear period (Table 8-C). The average and median of the absolute percent differences are included in the table. Precision of System Readings A subset of subjects wore two systems at the same time. This was to look at how similarly two systems function on the same subject (sensor precision). Precision was evaluated by comparing the glucose readings from the two systems worn on the same subject at the same time.  In the Original Adult Study, 36 subjects wore two systems. Results showed that system readings from the two sensors generally agreed with each other within 9% (absolute percent difference) with a 7% coefficient of variation. In the Original Pediatric Study, all subjects wore two systems. Results showed that system readings from the two sensors generally agreed with each other within 10% (absolute percent difference) with a 7% coefficient of variation. Only one system was worn in the Software 505 Adult and Software 505 Pediatric Studies, so precision data was not collected. Sensor Life Sensors may be worn for up to 7 days (168 hours). To estimate how long a sensor will work over 7 days, all sensors worn were evaluated to determine how many days/hours of readings each sensor provided.
 Dexcom G5 Mobile System User Guide Technical Information 296 In the Original Adult Study, 108 sensors were evaluated. Ninety-four percent (94%) of the sensors lasted until Day 7 (145-168 hours). There were 6 (6%) sensors that ended early, four of which lasted more than 3 days.  In the Software 505 Adult Study, 51 sensors were evaluated. Ninety-eight percent (98%) of the sensors lasted until Day 7 (145-168 hours). There was 1 (2%) sensor that ended early, which lasted until day 5 of the sensor wear. In the Original Pediatric Study, 351 sensors were evaluated. Eighty-five percent (85%) of the sensors lasted until Day 7 (145-168 hours).  In the Software 505 Pediatric Study, 77 sensors were evaluated. Ninety-four percent (94%) of the sensors lasted until Day 7 (145-168 hours). Table 9-A.

Number of Readings Provided The system is capable of providing a reading up to every 5 minutes, or up to 288 readings per day. For a variety of reasons, the system may not display a glucose reading and readings are “skipped.” Table 9-A and 9-B estimate the number of readings you can expect to receive from the system over the entire 7-day period after calibration. Table 10-A and 10-B show the number of readings you can expect to receive from the system within each system wear day. For the Software 505 Adult Study (SW10505), 96% of systems provided between 1497 and 1992 valid glucose readings (or more than 75% of the expected number of readings) as seen in Table 9-A. Adjusted within each system wear-day, the system in the Software 505 Adult Study provided an average of 98% of all expected glucose readings (288) as seen in Table 10-A.

 Dexcom G5 Mobile System User Guide Technical Information 304 Agreement and Accuracy Relative to SMBG Agreement between the system and BG values is also characterized using paired system and SMBG results (Table 11 to 12). The system and SMBG values were compared by pairing the comparative SMBG value to a system glucose reading that occurred immediately after the SMBG was collected. These results characterize the performance that subjects expect during real-time use of the system in their daily diabetes management when comparing the system readings to their home BG meter results. For readings less than or equal to 80 mg/dL, the absolute difference in mg/dL between the two glucose results was calculated. For values greater than 80 mg/dL, the absolute percent difference (%) from the SMBG values was calculated. The percentages of total readings within 15 mg/dL or 15%, 20 mg/dL or 20%, 30 mg/dL or 30%, 40 mg/dL or 40% or greater than 40 mg/dL or 40% were then calculated.  For example, if the system reads 100 mg/dL, it is between 81-180 mg/dL range and you can expect the system readings to be within 20% of the SMBG values 85% of the time for the Software 505 Adult Study, as seen in Table 11-A.  Overall, the system in the Software 505 Adult Study reads, on average, 2.6% lower (Mean Percent Difference) than SMBG values and 11.3% absolute different (Mean Absolute Percent Difference) than the SMBG values. The Median Percent Difference shows that half of the time the system reads lower in 2.7% or less than the SMBG values and the Median Absolute Percent Difference shows that half of the time the system reads about 8.6% or less different than SMBG values, as seen in Table 12-A. Adverse Events No serious adverse events or device-related serious adverse events occurred during the studies. Mild to moderate skin irritation, such as erythema or edema, occurred at the sensor needle insertion area or around the adhesive area. No infection, bruising, or bleeding occurred at the sensor needle insertion area or the adhesive area. 17.2 Product Specifications

Troubleshooting sections are categorized by function or system component. The solutions here are meant to be brief and not all inclusive, some have audible prompts, and others don’t. When more detailed answers or preventative measures are in a chapter, you’ll get a brief explanation here, and then get directed to the applicable chapter. After looking at the troubleshooting chapter, are you still not sure what to do? Or maybe your problem is hardware (for example, receiver or transmitter failure). If your problem is not found here, follow the steps listed on your app screen, or call Technical Support. If any of these errors continue and the instructions don’t resolve the issue, please contact Technical Support (available 24/7) at: • TechSupport@dexcom.com • Toll free: 1.888.738.3646 • Toll call: 1.858.200.0200  18.2 Safety Statements Following are the Safety Statements for the Troubleshooting chapter.
 Dexcom G5 Mobile System User Guide Troubleshooting 318 Warning Do: Calibrate at least once every 12 hours. Why: Calibrating less often than every 12 hours might cause inaccurate sensor glucose readings. Consequences: Missing severe low (hypoglycemia) or high (hyperglycemia) Alarm or Alerts.  Precaution Do: Enter the exact BG value displayed on your BG meter within five minutes of a carefully performed fingerstick measurement. Why: Entering the wrong BG values, or waiting more than five minutes before entry, might affect sensor accuracy.  Consequences: You may miss a severe low or high glucose event.  Precaution Don’t: Never prevent communication between transmitter and display devices. Do: Keep smart device and receiver within 20 feet of transmitter and away from obstructions. Why: If your transmitter display device(s) are more than 20 feet apart or are separated by an obstruction, they might not communicate. Types of obstruction differ and not all types have been tested. Obstructions can include water, walls, metal, etc. Water (for example, swimming, surfing, bathing, etc.) can severely limit communication range. Consequences: Missing severe low or high Alarm or Alerts. 18.3 Troubleshooting

Conditions Affecting Use
 Dexcom G5 Mobile System User Guide Sharing is Caring 344 Once sharing is active, make sure the Sharer’s and Follower’s smart device settings are not altered. Make sure the Sharer’s and Follower’s smart devices have: • Enough battery power to maintain sharing • Sharer’s smart device has Internet connection • Notifications turned on. If turned off, Follower won’t receive any notifications • Follower’s smart device has an Internet connection Dexcom recommends charging the smart device while sharing. 20.3 Risks and Benefits Risks Dexcom Share is a feature of the G5 Mobile . The main risks involved with using the Dexcom Share feature are based on misunderstanding its purpose.  Remember that the Dexcom Share feature in the G5 Mobile is a secondary notification feature, not a real-time remote monitoring system.  With using the Dexcom Share feature, there are three distinct parts of glucose monitoring:  1. BG meter: Use this to make any treatment decisions. 2. G5 Mobile: Use the G5 Mobile to complement, but not replace, information obtained from the BG meter. It detects glucose trends and tracks glucose patterns. 3. Dexcom Share: This is an optional add-on to the G5 Mobile that can share glucose information and notifications with up to five (5) other people. Shared sensor glucose readings and information can add another level of awareness. Using the wrong glucose information for treatment decisions could lead to low or high glucose. BG values from a BG meter may differ from the information displayed on the Dexcom Follow app. All treatment decisions should be made using a BG value from your meter, not the glucose information displayed on the Dexcom Follow app.
 Dexcom G5 Mobile System User Guide Sharing is Caring 345 Followers who are concerned by notifications on the Dexcom Follow app should contact the patients and remind them to check their BG with a BG meter before driving a car or making any treatment decisions, such as taking insulin or eating fast-acting carbohydrates. Sharers should not rely on Followers to notify them about low or high glucose.  Any problems with smart device(s), Bluetooth, wireless Internet connection, mobile data connection, Dexcom Share Cloud or not being in the communication range could cause data to not be shared with the Follower. In addition, if the Delay setting is too long, the Follower might not be aware of glucose level changes in a reasonable time. Therefore, the Dexcom Share feature should be used only to give a secondary level of awareness and should not be expected to always communicate and transfer sensor glucose readings and information. Benefits Patients usually respond when their continuous glucose monitoring (CGM) systems alert them. However, experts advise that an additional CGM alert to another person may be helpful in increasing the detection of low glucose or high glucose values, especially at night. The Dexcom Share feature enables this additional awareness, even when the Sharer and Follower are not in the same place.  The Dexcom Share feature may provide improved quality of life and greater peace of mind to patients, their caregivers and their support team by allowing the G5 Mobile Alarm, Alerts, and trend graphs to be checked remotely. 20.4 Safety Statement Intended Use The purpose of Dexcom Share Direct Secondary Displays is to notify another person, the Follower, of the patient’s Dexcom Continuous Glucose Monitoring (CGM) System sensor glucose information. The Secondary Displays is intended for providing secondary notification of a continuous glucose monitoring system and does not replace real time
 Dexcom G5 Mobile System User Guide Sharing is Caring 346 continuous glucose monitoring (Dexcom G5 Mobile System) or standard home BG monitoring. The Dexcom Share Direct Secondary Displays is not intended to modify or analyze data received from the continuous glucose monitoring system, nor is it intended to instruct, or to transmit information to the continuous glucose monitoring system. The Dexcom Share Direct Secondary Displays is not intended to serve as a replacement for a primary display device for a continuous glucose monitoring system. The Dexcom Share Direct Secondary Displays is not intended to receive information directly from the sensor or transmitter of a continuous glucose monitoring system. Important User Information Please review the indications, contraindications,  warnings, precautions, cautions and other important information in the G5 Mobile user guide. Dexcom Share is a feature of the G5 Mobile.  If you do not have the Dexcom G5 Mobile System User Guide, you can view it on dexcom.com or call 1.888.738.3646 to request a copy. Availability hours: Monday-Friday, 6am-6pm PST. Please contact your healthcare professional during hours the line is unavailable. Contraindications Do not bring the smart device (e.g., mobile phone, tablet computer) into a room containing medical equipment such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT), or diathermy. These smart devices have not been tested with this equipment. Exposure to these types of equipment could heat and damage the smart devices so that they are unable to send or receive glucose information. Warnings Dosing decisions should not be made based on this device. The user should follow instructions on the continuous glucose monitoring system.  This device is not intended to replace self-monitoring practices advised by a physician. Dexcom Share does not work alone. Dexcom Share does not
 Dexcom G5 Mobile System User Guide Sharing is Caring 347 replace the Dexcom G5 Mobile System and requires Share to be turned “On” to communicate glucose information to the Follower. You cannot use Dexcom Share to make treatment decisions, such as how much insulin to take. Dexcom Share does not replace a BG meter. Always use the values from a BG meter for treatment decisions. BG values may differ from the sensor glucose information. Using the sensor glucose information for treatment decisions could lead to low or high BG values. Precautions Do not use Dexcom Share as the main source of CGM glucose trend information. Use the G5 Mobile receiver as the main device to track sensor glucose information, notifications and Alarm. At times, the patient will be unable to share data using Dexcom Share, and the Follower might miss helping the patient in the event of low or high BG values. Do not rely solely on the Follower to alert the patient of low or high glucose events or other important information. At times, the Follower may not receive data, and the patient will not be notified of this fact.  When using Dexcom Share, make sure Share is turned “On.” If not, the patient will be unable to share data, and the Follower might miss helping the patient in the event of low or high BG values. If the patient’s smart device does not have a connection or loses the connection, the patient will be unable to share data, and the Follower might miss helping the patient in the event of low or high BG values.  Do not use Dexcom Share unless both the patient’s and Follower’s smart devices have active Internet connections in order to share data. If either the patient or the Follower does not have a connection, loses their connection, turns off the connection (“Airplane Mode”) or if the smart device is in Do Not Disturb mode, the patient will be unable to share data and the Follower might miss helping the patient in the event of low or high BG values. To check this, make sure that the Follower’s smart device can receive text messages. Follow notifications and text messages work by a similar process.  Make sure the patient’s and Follower’s smart devices have charged batteries or are connected to electrical outlets. If the smart device shuts down due to
 Dexcom G5 Mobile System User Guide Sharing is Caring 348 low battery, the patient will be unable to share data, and the Follower might miss helping the patient in the event of low or high BG values.  If the patient’s smart device is powered off or restarted, make sure the G5 Mobile app is reopened after the smart device is turned back on in order to resume sharing. If the G5 Mobile app is not reopened, the patient will be unable to share data, and the Follower might miss helping the patient in the event of low or high BG values.  Do not turn off sounds in the Follower’s smart device at any time that he or she wants Follow notifications to be heard. The smart device settings override the Dexcom Follow app, and all notifications will be silent even if the Follower has selected a Dexcom Follow app notification sound. If the smart device has a vibrate feature and vibrate is On, the Dexcom Follow app notifications will only vibrate.  Check the delay settings on the patient’s smart device to make sure they are not too long. The Follower will not receive notifications until after the time period in the delay has passed, and the Follower might miss helping the patient in the event of low or high BG values if the delay is too long.  The patient should not choose to “Not Share” with the Follower at any time when he or she wants the Follower to get notifications. During the time the patient chooses to “Not Share,” the Follower will not receive notifications and might miss helping the patient in the event of low or high BG values. Check the Dexcom Follow app’s trend graph if the Follower’s smart device has been off or if there is no data connection (for example, Internet/Wi-Fi or mobile data service/3G/4G/LTE is lost, connection is turned off in Airplane Mode, or smart device touch is placed in Do Not Disturb mode). When the smart device is turned back on, the Follower will only receive the most recent notification and might miss helping the patient in the event of prior low or high BG values.  Sharers and Followers should check whether their cellular service carriers support voice and data at the same time (simultaneous voice and data). If their carriers do not support simultaneous voice and data, the G5 Mobile app may not be able to share glucose readings and the Dexcom Follow app may not be able to receive notifications or glucose readings during phone calls.
 Dexcom G5 Mobile System User Guide Sharing is Caring 349 Dexcom Share will resume sharing after the phone call has ended, and the Follower will receive any waiting notifications after the phone call has ended.  20.5 Setting Up Dexcom Share Dexcom Share Description What Dexcom Share does: • Connects your smart device with your Follower’s smart device via either a Wi-Fi or mobile data connection (connect to Wi-Fi through a secured network to maintain data security) • Invites and sends Followers your setting recommendations • Displays the status of your smart device, and the Dexcom Share Cloud o Confirms your sensor glucose readings are being shared with your Follower(s) What Dexcom Share does not do: • Let you know when the Follower is not receiving your sensor glucose readings and information Tips • Read the rest of the G5 Mobile user guide before using Dexcom Share • Always confirm information with a BG meter before making treatment decisions • Check the status screen after turning Dexcom Share “On” on the smart device to make sure it is working Installing the G5 Mobile App Step What you see What you do
