Indications for Use and Safety Statements 2.1 Introduction In this chapter, youll learn how to use the G6 safely. Review this chapter before using the G6. Youll find:

How following the safety statements keeps you safe How to interpret safety statements An overview of safety statements 2.2 What Are Safety Statements?

Safety statements are brief explanations meant to keep you and the system safe while using the G6. There are four types:

Warnings: Describe serious even life-threatening situations to avoid when you use the G6 Precautions/Cautions: Are steps you take when using the G6 to prevent minor or moderate harm to you or the system Indications: Show who should use the system as well as when, why, and how they should use it Contraindications: Let you know when not to use the G6. If used in these situations, you may hurt yourself or the system 2.3 How to Read Safety Statements You see safety statements in two formats:

List: All safety statements are listed in the next section Boxes: Chapters include boxes with the safety statements related to that content Within chapters, each safety statement is in a box, broken down into four sections, like the example below:

2.4 Overview of Safety Statements This section reviews all safety statements what you should or shouldnt do, why, and what could happen. The statements are grouped by system function or feature. Review the safety statements to be aware of the indications, contraindications, warnings, precautions, and cautions listed below. If you dont follow these instructions, you could over or under treat because you may not realize your glucose is very low or high (hypoglycemia or hyperglycemia). And of course, seek medical attention when appropriate. General CGM System Safety Statements Indication Who, What, and Why?

o Who:

You can use the system if youre 2 years or older and have diabetes. To get the G6, your healthcare LBL014003 Rev 001 Dexcom G6 User Guide 7 professional (HCP) writes you a prescription. Dont share your device. Use one Dexcom account for each patient. o What:

The system tracks your glucose patterns and detects trends while they happen. The G6 is designed to replace fingerstick blood glucose (BG) testing for diabetes treatment decisions. o Why:

Manage your diabetes using the system information readings, arrows, and alarm/alerts. Every 5 minutes, the sensor reports your sensor glucose reading (reading) on your display device. Over time, youll see trends and patterns. The system shows you your low and high glucose periods so you can act when needed and create long-term treatment plans with your HCP. These actions and plans help you spend more time in your target glucose range and reduce your A1C. Contraindication No MRI/CT/Diathermy MR Unsafe Dont wear your CGM (sensor, transmitter, receiver, or smart device) for magnetic resonance imaging

(MRI), computed tomography (CT) scan, or high-frequency electrical heat (diathermy) treatment. The system hasnt been tested in those situations. Magnetic fields and heat could stop readings or alarm/alerts. Without readings or alarm/alert notifications, you might miss a severe low or high glucose event. Warnings Read User Materials Before you use your G6, carefully read the materials included with it. If you dont, you might:

o Not use the system correctly o Not understand system information o Affect how well it works Dont Ignore Low/High Symptoms Dont ignore how you feel. If your glucose alerts and readings dont match what youre feeling, use your blood glucose meter (meter) to make diabetes treatment decisions or, if needed, seek immediate medical attention. When in doubt, get your meter out. No Number, No Arrow, No CGM Treatment Decision If your G6 doesnt show a number or arrow, or your readings dont match your symptoms, use your meter to make diabetes treatment decisions. No number, no arrow, no treatment decision. When in doubt, get your meter out. Dont Use If Dont use the system if you are:

o Pregnant o On dialysis o Critically ill We havent tested people in these conditions so we dont know if these affect accuracy. Follow system instructions. If you dont, you could have a severe low or high glucose event. Calibration Safety Statements Warnings Dont Wait Calibrate!

The system needs your meter values every day to provide accurate information. Calibrate immediately when notified. If you havent calibrated when notified, use your meter to make treatment decisions until you calibrate your G6. When you insert a new sensor be sure to calibrate as soon as the system notifies you. Youre notified to calibrate twice, then once more after 12 hours, and again 12 hours later. For the rest of your session, you are notified at least once every 24 hours. Use Meter During Startup When you start a new sensor, you wont get any readings or alarm/alerts until you enter two calibrations. Use your meter to make treatment decisions during the 2-hour sensor warmup period. LBL014003 Rev 001 Dexcom G6 User Guide 8 Use Fingersticks Use fingertips to calibrate from your meter. Blood from other places may be less accurate and not as timely. Follow system instructions. If you dont, you could have a severe low or high glucose event. Precautions Be Accurate, Be Quick Enter the exact BG value displayed on your meter within 5 minutes of using your meter. Dont enter the G6 reading as a calibration. Dont Calibrate When Glucose Rate Is Changing Fast Dont calibrate when your trend arrow is up, double-up, down, or double-down because your BG is changing at more than 2 mg/dL per minute. Follow system instructions. If you dont, you could have a severe low or high glucose event. System/Hardware/Software Safety Statements Warnings Wire Breaks Off Dont ignore broken or detached sensor wires. A sensor wire could remain under your skin. If this happens, please contact our 24/7 Technical Support. If a sensor wire breaks off under your skin and you cant see it, dont try to remove it. Contact your HCP. Also seek professional medical help if you have symptoms of infection or inflammation redness, swelling, or pain at the insertion site. Where to Insert: Belly or Behind?

All patients can use their bellies. Patients 2 to 17 years old can also choose their upper behinds. Look for a place on your belly or upper behind where you have some padding. The sensor is not tested or approved for other sites. Talk to your HCP about the best site for you. Ages 2-17 years: Insert in your belly or upper behind Ages 18 and older: Insert in your belly Where to Store You can store your sensors at room temperature or in your refrigerator as long as its between 36 F and 86 F. Dont store sensors in the freezer. Follow system instructions. If you dont, you could have a severe low or high glucose event. Precautions Dont Use if Expired Dont use expired sensors, because they may give incorrect results. Check the package label for the expiration date. Its in YYYY-MM-DD format. Check Package Dont use sensor if its sterile package has been damaged or opened, because it might cause an infection. Clean and Dry Skin LBL014003 Rev 001 Dexcom G6 User Guide 9 Clean and dry your hands and your insertion site before inserting your sensor. Wash your hands with soap and water, not gel cleaners, and then dry them before opening the sensor package. If your hands are dirty when you insert the sensor, you may get germs on the insertion site and get an infection. Clean your insertion site with alcohol wipes to prevent infections. Dont insert the sensor until your skin is dry. If your insertion site is not clean and completely dry, you run the risk of infection or the transmitter holder not sticking well. Make sure you dont have insect repellant, sunscreen, perfume, or lotion on your skin. Where to Insert: Things to Check Keep the safety guard on until you put the G6 applicator against your skin. If you remove the safety guard first, you may hurt yourself by accidentally pushing the button that inserts the sensor before you mean to. Change your insertion site with each sensor. 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:

o At least 3 inches from insulin pump infusion set or injection site o Away from waistband, scarring, tattoos, irritation, and bones o Unlikely to be bumped, pushed, or laid on while sleeping Follow system instructions. If you dont, you could have a severe low or high glucose event. Transmitter Safety Statements Warnings Inspect Dont use a damaged or cracked transmitter. A damaged transmitter could cause injuries from electrical shocks and may make the system not work correctly. Use as Directed The transmitter is small and may pose a choking hazard. Dont put it in your mouth or let children hold it without adult supervision. Follow system instructions. If you dont, you could have a severe low or high glucose event. Precautions Reuse Dont Throw Away When ending a session, dont throw away the transmitter. The transmitter is reusable until the system notifies you that the transmitter battery is about to expire. Dont Share Never share your transmitter. The system is a prescription-only medical device and is meant for your use only. The transmitter is tied to the sensor glucose readings. If used by more than one person, the glucose readings, reports, alarm/alerts, etc., may be wrong. Follow system instructions. If you dont, you could have a severe low or high glucose event. System Safety Statements Precautions Treatment Decisions Use your sensor glucose reading and trend arrow to make treatment decisions. Use Correct Transmitter, Receiver, and Sensor G6 components are not compatible with any previous Dexcom products. Do not mix transmitters, receivers, and sensors from different generations. Dont Use When Glucose Rate Is Changing Fast Your sensor reading may be wrong when your glucose is changing 3 mg/dL or more each minute. This LBL014003 Rev 001 Dexcom G6 User Guide 10 can happen during exercise or after a meal. Going Through Security Check Point When wearing your system, ask for 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) or putting any part of the system in the baggage x-ray machine. You can wear the system for the walk-through metal detector. If you do, use your meter for treatment decisions until you leave the security area. Because we havent tested every x-ray and scanner, we dont know if they damage the system. Not sure what kind of machine it is? Be safe either ask the TSA officer, request hand-wanding, or request full-body pat-down. Follow system instructions. If you dont, you could have a severe low or high glucose event. Receiver and Smart Device Safety Statements Precautions Keep Transmitter Close to Display Device Keep your transmitter and display device within 20 feet with no obstacles (like walls or metal) between them. Otherwise, they might not be able to communicate. If water is between your transmitter and the display device -- for example, if youre showering or swimming keep them closer to each other. The range is reduced because Bluetooth doesnt work as well through water. Get Alarm/Alerts on Display Device You Use To get your alarm/alerts, set them on the display device you use. Your receiver wont get the alarm/alerts you set on your app. Likewise, your app wont get the alarm/alerts you set on your receiver. Is It On?

If the receiver or smart device is turned off (shut down), it will not show readings or alarm/alerts. Make sure your display device is turned on. Follow system instructions. If you dont, you could have a severe low or high glucose event. Smart Device Safety Statements Warnings Check Settings When using your smart device, check:

o Volume/muted/headphones You get a visual notification and a vibration (if your device has a vibration feature). You may not hear the sound on your first notification. If you dont clear it within 5 minutes, the alarm/alert repeats at half volume and at full volume after 10 minutes. Your alarm and important alerts sound and display information even when your volume is low or muted. Specifically, if your smart device is on mute, only these notifications make a sound:

o Glucose Alarm/Alerts:

Urgent Low Urgent Low Soon Low Glucose High Glucose Rise Rate Fall Rate No Readings Alert o System Alerts:

Calibration Required (after 2-hour sensor warmup) Calibration Error Sensor Expired Replace Sensor Transmitter (not working) No Storage Error App Stopped LBL014003 Rev 001 Dexcom G6 User Guide 11 Theres one exception: On Apple devices, Signal Loss doesnt sound when your volume is low or muted. When you have headphones connected to your Android, alarm/alerts will sound through the headphones and the speaker. On your Apple, they will sound only in the headphones. o Bluetooth: Your transmitter talks to your app with Bluetooth. Make sure your smart device Bluetooth is on. If not, you will not get alarm/alerts or CGM information. o Notifications:

Make sure your smart device settings allow Dexcom app notifications to show on your Lock screen. Apple: During setup, enable Dexcom app notifications or you wont get alarm/alerts. o Battery: The app must always be running in the background and may drain your smart device battery. Keep the battery charged. o Compatibility: Before upgrading your smart device or its operating system, check dexcom.com/compatibility. Automatic updates of the app or your device operating system can change settings or shut down the app. Always update manually and verify correct device settings afterward. o Time: Let the date and time on your smart device automatically update when you travel across time zones or switch between standard and daylight saving times. Dont manually change your smart device time, because it can make the time on the trend screen wrong and the app may stop displaying data. Follow system instructions. If you dont, you could have a severe low or high glucose event. Precautions Check Accessory Devices Do you use headphones with your smart device? What about Bluetooth speakers or a smart watch?

When using accessories, keep in mind you may get your alarm/alerts on only one device or accessory, not all. After connecting any accessory devices, make sure that your smart device settings allow you to continue receiving alarms or alerts. Follow system instructions. If you dont, you could have a severe low or high glucose event. Receiver Safety Statements Warnings Dont Use if Damaged Dont use a receiver that is damaged or cracked. A damaged receiver could cause injuries from electrical shocks and may make the system not work correctly. Use Cable as Directed Use USB cable only as directed, and store safely. Misuse of the USB cable can be a strangulation risk. Follow system instructions. If you dont, you could have a severe low or high glucose event. Precautions Test Speaker and Vibrations You have to hear or feel alarm/alerts to react to them, so test your receiver speaker and vibrations regularly. To make sure the speaker and vibrations work, plug in the receiver to charge. The Speaker Test screen appears for a few seconds. Follow the directions on the screen to test the speaker and vibrations. If you hear and feel them, great! But if it doesnt beep and vibrate -- perhaps it got wet or was dropped -- contact Technical Support and use your app until the receiver is fixed. Keep Clean and Dry Dont submerge your receiver in water and dont get dirt or water in the USB port. That could damage it. Follow system instructions. If you dont, you could have a severe low or high glucose event. Caution Requires HCP Prescription U.S. law restricts the sale of the G6 Mobile to sale by, or on the order of, a physician.

Can explain how safety statements keep you safe Can explain how to interpret safety statements Have an overview of safety statements Whats Next?

In the next chapter, youll learn the risks and benefits of using the G6. LBL014003 Rev 001 Dexcom G6 User Guide 14 Chapter 3 Get Started:

Risks and Benefits When using any medical device, there are risks and benefits. In this chapter, youll learn what they are. 3.1 Risks The risks with using G6 are:

Not getting your alarm/alerts Using G6 to make treatment decisions when you shouldnt Sensor insertion issues This section covers each of those risks in detail. Follow system instructions. If you dont, you could have a severe low or high glucose event. Not Getting Alarm/Alerts If you arent getting your alarm/alerts, you could have severe low or high glucose without knowing it. Check your display device:

Battery charged: If the display device battery is dead, you wont get readings or alarm/alerts. App on: Keep the app on so you get readings or alarm/alerts. Alerts on: Leave the alert function on to get alarm/alerts. Volume up: Keep the volume loud enough to hear your alarm/alerts. Speaker and vibrations work: If the speaker or vibrations arent working, you wont hear or feel your alarm/alerts. In range: Keep your display device no more than 20 feet from your transmitter, with no obstacles between them. They have to be that close to communicate. If they arent in range, you wont get readings or alarm/alerts. No System errors: If you get a system error - such as No Readings, Sensor Error, or Signal Loss - you wont get readings or alarm/alerts. During warmup and after session ends: You wont get alarm/alerts or readings during the 2-hour warmup or after a sensor session ends. See Troubleshooting (Chapter 14), recommended settings (Chapter 5), and notifications that sound while smart device is silenced/muted (Appendix I) for more information. Using G6 for Treatment Decisions You can use your G6 to treat for a low or dose for a high in all but these few situations:

No number, no arrow, no CGM treatment decision: If you have a reading and a trend arrow, you can use those to make a treatment decision. Otherwise use your meter. Dont wait calibrate: If youve calibrated immediately when prompted, your G6 is accurate and you can use it to make a treatment decision. Otherwise use your meter until you calibrate your G6. When in doubt, get your meter out: If you feel like your glucose is low or high but your G6 number is within your target range, verify with your meter. Likewise, if you care for someone using the G6, watch how they act. If their symptoms dont match the G6, use the meter. Use your G6 for treatment decisions, not your Followers: Dexcom Share allows you to share your sensor glucose information from your smart device to your Followers. The main risk with Share is misunderstanding its purpose. The information on your display device is the most current it comes straight from your transmitter so only use yours for treatment decisions. There can be technical issues and delays in sharing information. Followers can reach out and support you, but dont rely on them or their information to manage your diabetes for you. Some users found accuracy between different sensors varied significantly. When you insert each sensor, pay attention to its accuracy before deciding to use it for treatment decisions. For more information on how to make treatment decisions using your G6, see Chapter 11. For more information on Share, see Chapter 12. LBL014003 Rev 001 Dexcom G6 User Guide 15 Sensor Insertion Risks Its uncommon, but inserting the sensor can cause infection, bleeding, or pain, and wearing the adhesive patch can irritate your skin. Only a few patients in the G6 clinical studies got slight redness and swelling. 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 usually dont pose a significant medical risk. If a sensor wire breaks off or detaches and remains under your skin, contact your HCP and Technical Support (24/7):

TechSupport@dexcom.com Toll free: 1.888.738.3646 Toll call: 1.858.200.0200 3.2 Benefits Some benefits of using your G6 are:

Knowing your trends Making treatment decisions using your G6 Managing your diabetes Getting alerted for low and high readings This section covers each of those benefits in detail. Knowing Your Trends The G6 sends you a reading every 5 minutes. It also provides reports and views of your information so you can detect and reflect on trends, patterns, and how your body responds to different things, like exercise or pizza. This provides you with a more complete picture of your glucose and lets you see how your daily habits impact your A1C. Making Treatment Decisions Using G6 You can use your G6 reading and trend arrow to make treatment decisions like treating for a low or dosing for a high. See Chapter 11 for more information on treatment decisions. With G6, theres no need to confirm your reading with a fingerstick. This can reduce the pain and burden of excessive fingersticks (Aleppo 2017). Helping Your Diabetes Management The alarm/alerts features (Chapter 10) keep you aware of your glucose levels. Alarm/alerts notify you when your glucose goes outside your target range, goes too low, or is falling too fast. This lets you take action to prevent glucose from going too low or high (Pettus 2015). Over time, you spend more time in your target range and less time being too high or too low (Beck 2017; Lind 2017). This gives you more control over your glucose, may help you improve your A1C, and may reduce your risk of long-term diabetes-related complications (The Diabetes Control and Complications Trial Research Group 1993). Some patients gain peace of mind and a better quality of life when using real-time CGM, such as G6

(Polonsky 2017). Share may improve the quality of life and peace of mind for patients, their caregivers, and their support team because it sends Followers readings and alarm/alerts remotely. Followers can then reach out when readings go too low or high.

Now lets take a look at the G6!

LBL014003 Rev 001 Dexcom G6 User Guide 17 LBL014003 Rev 001 Dexcom G6 User Guide 18 Chapter 4 Lets G6! The Basics:

What Is the G6?

4.1 Introduction This chapter is an overview of the G6 System. After this chapter, youll be able to:

Explain what G6 does List whats new in G6 Explain each components function 4.2 G6 CGM System The G6 is a medical device you use on yourself. It allows you to continually see your readings, updated every 5 minutes for up to 10 days, without the bother of taking constant fingerstick measurement. Youll see:

BG readings: Update every 5 minutes. Trend arrows: Show where your BG is heading. Alarm/alerts: Warn you when you need to take action, for example, when your BG is too high or too low. History: Graphs show the last 1, 3, 6, 12, and 24 hours of your readings. Reports: Web-based reports reflect your glucose trends and patterns. Share reports with your HCP when developing your diabetes management plans. 4.3 Whats New for G6?

Dexcoms G6 features include:

Treatment decisions: Use your sensor glucose information to make diabetes treatment decisions Calibrate once a day: After youre set up, you only need to calibrate every 24 hours and when notified Sensor session length: Wear your sensor for up to 10 days Overpatch: Use it to cover the patch and help keep your sensor on Urgent Low Soon: Get an alert when your glucose is quickly heading toward 55 mg/dL Treatment Decisions The G6 allows you to make treatment decisions without using your meter. With the G6 number and trend arrow, you know where your glucose is and where its heading. Based on your G6, you determine if you should dose, eat carbs, or do nothing no fingerstick needed!

You still need your meter to calibrate and as a backup when your CGM data do not reflect how you feel or if you dont have enough information on your home screen. For more information, go to Chapter 11. Urgent Low Soon Alert Sometimes glucose levels fall fast. Really fast. The Urgent Low Soon Alert lets you know when yours is falling so fast it will drop to 55 mg/dL in less than 20 minutes. This gives you time to prevent going too low. For this alert, it doesnt matter where your glucose is now; it matters where it is heading. For more information, go to Chapter 10. 4.4 G6 Components The G6 has three key parts:

Sensor Transmitter Display Device: Dexcom Receiver and/or Dexcom app on your smart device LBL014003 Rev 001 Dexcom G6 User Guide 19 Each part comes in its own package. Keep the packaging until youre no longer using its contents. Sensor Overview For your safety, the single-use sensor is packaged in a sterile sealed pouch. When you open the package, your sensor looks like one item, but its actually three: sensor applicator, transmitter holder, and sensor wire. The applicator helps you insert the sensor wire under your skin. After inserting the sensor wire, you can throw away the applicator. Youll see the transmitter holder held onto your body with the adhesive patch. The sensor wire is attached to the other side of the holder. Once inserted, the sensors thin, flexible wire measures your glucose levels in the fluid between your cells

(interstitial fluid) for up to 10 days. Heres the applicator:

Transmitter Overview The front and back of the transmitter look like this:

The transmitter snaps into the transmitter holder and wirelessly sends your glucose information to your display device(s). The transmitter is reuseable. If you have a new transmitter, open the package when youre ready to use it. Display Device Overview LBL014003 Rev 001 Dexcom G6 User Guide 20 You can choose which display device(s) to use: the Dexcom Receiver (receiver), the Dexcom G6 App (app) downloaded on your smart device, or both. They both show your readings, graphs, and trend arrows and alert you when theres something you should be aware of. For a list of current compatible smart devices and operating systems go to: dexcom.com/compatibility This User Guide is not meant to show you how to use your smart device. Contact your smart device support or read your smart device user guide for assistance. The receiver is not water resistant or waterproof and can get damaged if moisture gets inside, so keep it away from 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 14). You can change the receiver protective case. Just take off the black one and put on one of the colored ones. Be sure to line up the covers speaker holes with the receiver speaker. G6 and Previous Dexcom System Components The G6 is not compatible with previous generations such as the Dexcom G4 PLATINUM CGM System or the Dexcom G5 Mobile system. You cant mix the transmitter or receiver between the two systems. However, if you have the touchscreen Dexcom Receiver, you can upgrade it to G6. PRECAUTION Do: Use correct transmitter, receiver, and sensor. Why: G6 components are not compatible with any previous Dexcom products. Consequences: You could have a severe low or high glucose event. 4.5 Whats Covered and Whats Coming Now You Can:

Explain what G6 does List whats new in G6 Explain each components function Next Steps Your next step is setting up your display device(s). LBL014003 Rev 001 Dexcom G6 User Guide 21 Chapter 5 Lets G6! The Basics:

Set Up Your Display Devices 5.1 Introduction This chapter shows you how to choose and set up your display device(s). After this chapter, youll be able to:

Determine which display device(s) youll use Create a Dexcom username and password Implement the suggested settings on your smart device Download and set up the G6 app Set up your receiver 5.2 Choose the Receiver, the App, or Both You can use the receiver, the app, or both. Choose the device thats best for you. The main difference between them is the app has Dexcom Share (Share). It lets you send your glucose information to others in real time so they can support you in your care. You can also schedule long-acting insulin dose reminders in the app. On the other hand, the receiver is a dedicated medical device, so it isnt using battery life to support texts or photos, the way your smart device is. If youre concerned about missing an alarm/alert (for example, due to smart device settings, app shutting off due to lack of storage, low smart device battery, your smart device being damaged, lost, or stolen, etc.), bring your receiver with you. Whether you carry the app or the receiver, remember to keep your display device on. PRECAUTION Do: Make sure your display device is turned on. Why: If the receiver or smart device is turned off (Shut Down), it will not show readings or alarm/alerts. Consequences: You could have a severe low or high glucose event. The next section walks you through setting up the app. To set up the receiver, go to the following section. If you want to use both, you need to set each up individually. To set up accessory devices, see Appendix D. 5.3 App Before starting your first sensor, pick the smart device you want to use. You can use the receiver with one smart device during a session; however, you cant use multiple smart devices during the same session. Part of your setup is entering the transmitter serial number (SN). If by accident you enter the SN into more than one smart device, the system warns you and you wont be able to complete the setup process. Suggested Smart Device Settings See your smart device instructions to learn how to change its settings. Use the following with your CGM system:
