System Overview

Dexcom SHARETM remote monitoring system lets one person, the Sharer, transfer
Dexcom G4TM PLATINUM Continuous Glucose Monitoring information to another
person, the Follower. Dexcom SHARE consists of the following components:
Dexcom G4 PLATINUM System, Cradle,
Sharer’s iPhone® or iPod® Touch, the Dexcom ShareTM app, the internet, the
Follower’s iPhone or iPod touch and the Dexcom FollowTM app.

16 Learning About Dexcom SHARE

Conditions That Affect Use

Dexcom SHARE should not be used in a wet environment. Once
Sharing is established, make sure the settings on the Cradle,
Sharer’s iPhone or iPod touch and Follower’s iPhone or iPod touch
are not altered. Make sure the Sharer’s iPhone or iPod touch and
Follower’s iPhone or iPod touch have enough battery power to
maintain Sharing. Dexcom recommends charging both iPhone or
iPod touch when Sharing.

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, especially at night.
Dexcom SHARE enables this additional awareness, even when the
Sharer and Follower are not in the same place.

Dexcom SHARE may provide improved quality of life and greater
peace of mind to patients, their caregivers and support team by
allowing the Dexcom G4 PLATINUM System alerts, alarms and
trend graphs to be checked remotely.

17 Learning About Dexcom SHARE

Indications for Use

The purpose of Dexcom SHARE is to notify another person, the
Follower, of the patient’s Dexcom G4 PLATINUM Continuous
Glucose Monitoring System sensor glucose information when the
G4 PLATINUM Receiver is docked in the Dexcom SHARE Cradle.
Dexcom SHARE provides secondary notification and does not
replace real time continuous glucose monitoring (G4 PLATINUM
System) or standard home blood glucose monitoring.

Contraindications

There are no contraindications for Dexcom SHARE.

Important User Information

Please review the indications, contraindications, warnings,
precautions, cautions and other important information in the
Dexcom G4 PLATINUM System User’s Guide. Dexcom SHARE is
an optional accessory of the Dexcom G4 PLATINUM System. If
you do not have the Dexcom G4 PLATINUM System User’s Guide
you can view it on www.dexcom.com or call 1-888-738-3646 to
request a copy.

18 Learning About Dexcom SHARE

Warnings

Dexcom SHARE does not work alone. Dexcom SHARE does
not replace the Dexcom G4 PLATINUM System and requires the
Dexcom G4 PLATINUM Receiver to be docked in the Dexcom
SHARE Cradle to communicate glucose information to the Follower.
Dexcom SHARE is not compatible with any previous Dexcom®
CGM System or any other CGM device.

You cannot use Dexcom SHARE to make treatment decisions, such
as how much insulin to take. Dexcom SHARE does not replace a
blood glucose meter. Always use the values from a blood glucose
meter for treatment decisions. Blood glucose values may differ
from the sensor glucose information. Using the sensor glucose
information for treatment decisions could lead to low or high blood
glucose values.

Precautions

Do not use Dexcom SHARE as the main source of CGM glucose
trend information. Use the Dexcom G4 PLATINUM Receiver as
the main device to track sensor glucose information, notifications
and alarms. At times, the patient will be unable to share data using
Dexcom SHARE, and the Follower might miss helping the patient in

19 Learning About Dexcom SHARE

the event of low or high blood glucose 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 the Dexcom G4
PLATINUM Receiver is docked in the Cradle and fully connected.
Make sure the charger cable is connected to the Cradle and
plugged into the electrical outlet. 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 blood glucose values.

Set the Dexcom G4 PLATINUM Receiver to a sound alert when
the receiver is docked in the Dexcom SHARE Cradle. Do not set
the receiver to “vibrate” profile. You may not notice the receiver
vibrations when the receiver is docked in the Cradle, and you may
miss a CGM alert.

and obstructions between the Cradle and the iPhone or iPod touch.
If the patient’s iPhone or iPod touch 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 blood glucose values.

Do not use Dexcom SHARE unless both the patient’s and Follower’s
iPhone or iPod touch have active internet connections in order
to share data. If either the patient or the Follower do not have a
connection, lose the connection, turn off the connection (“airplane
mode”) or if either iPhone or iPod touch 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 blood glucose values.
To check this, make sure that the Follower’s iPhone or iPod touch
can receive text messages. Follow notifications and text messages
work by a similar process on iPhone or iPod touch.

Bluetooth

range can vary and depends on the distance

Make sure the patient’s and Follower’s iPhone or iPod touch have
charged batteries and are connected to electrical outlets. If not,
the patient will be unable to share data, and the Follower might miss

21 Learning About Dexcom SHARE

helping the patient in the event of low or high blood glucose values.

If the patient’s iPhone or iPod touch is powered off or restarted, make sure the
Dexcom Share app is reopened after the iPhone or iPod touch is turned back on in
order to resume sharing. If the Dexcom Share 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 blood glucose values.

Do not turn off system sounds in the Follower’s iPhone or iPod
touch at any time that he or she wants Follow notifications to be
heard. The iPhone or iPod touch 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 iPhone
or iPod touch is on vibrate, the Dexcom Follow app notifications will
only vibrate.

Check the delay settings on the patient’s iPhone or iPod touch
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 blood glucose 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 blood glucose values.

22 Learning About Dexcom SHARE

Check the Dexcom Follow app’s trend graph if the Follower’s
iPhone or iPod touch has been off or if there is no data connection
(e.g., internet/Wi-Fi or mobile data service/3G/4G/LTE is lost,
connection is turned off in airplane mode, or iPhone or iPod touch is
placed in do not disturb). When the iPhone or iPod touch 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
blood glucose 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 Dexcom Share app may not be able to share
glucose values and the Dexcom Follow app may not be able to
receive notifications or glucose values during phone calls. 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.

Risks

Dexcom SHARE is an optional accessory to the Dexcom G4TM
PLATINUM Continuous Glucose Monitoring (CGM) System. The
main risks involved with using Dexcom SHARE are based on
misunderstanding its purpose.

Remember that Dexcom SHARE is a secondary notification system,
not a real-time remote monitoring system. With Dexcom SHARE,
there are 3 distinct parts of glucose monitoring:

1. Blood glucose meter - use this to make any treatment decisions.

2. Dexcom G4 PLATINUM CGM System - use the Dexcom G4
PLATINUM System to complement, but not replace, information

obtained from the blood glucose meter. It detects glucose

23 Learning About Dexcom SHARE

trends and tracks glucose patterns.

3. Dexcom SHARE - this is an optional add-on to the Dexcom
G4 PLATINUM System that can share glucose information and
notifications with up to five (5) other people. Shared glucose
information can add another level of awareness.

Using the wrong glucose information for treatment decisions
could lead to low or high glucose. Blood glucose values from a
blood glucose meter may differ from the information displayed on
Dexcom Follow app. All treatment decisions should be made using
a blood glucose meter, not the glucose information displayed on the
Dexcom Follow app. Followers who are concerned by notifications
on the Dexcom Follow app should contact the patients and remind
them to check their blood glucose with a blood glucose 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 the Cradle, iPhone or iPod touch,

Bluetooth

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

24 Learning About Dexcom SHARE

, wireless internet connection, mobile data connection,

of glucose level changes in a reasonable time. Therefore, Dexcom
SHARE should be used only to give a secondary level of awareness
and should not be expected to always communicate and transfer
sensor glucose information.

Jailbroken iPhones and iPod touches

Dexcom requires patients and Followers to not use Dexcom SHARE
apps on a jailbroken iPhone or iPod touch. A jailbroken iPhone or
iPod touch do not offer a reliable means to use Dexcom SHARE.
They present an unacceptable level of security and inaccuracy risk
to the user and are not authorized to use Dexcom SHARE.

User Agreement

Your use of Dexcom SHARE system is subject to the terms of the
most current Dexcom SHARE End User License Agreement posted
at www.dexcom.com/share, and the Dexcom SHARE Privacy Policy
posted at www.dexcom.com/share, as those documents are
updated from time to time according to their terms.

Interference may occur
in the vicinity of
equipment marked with
following symbol:

NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by

absorption and reflection from structures, objects and people.

76 Technical Information

a. Field strengths from fixed transmitters, such as base stations for radio

(cellular/cordless) telephones and land mobile radios, amateur radio, AM

and FM radio broadcast, and TV broadcast cannot be predicted theoretically

with accuracy. To assess the electromagnetic environment due to fixed RF

transmitters, an electromagnetic site survey should be considered. If the

measured field strength in the location in which the Dexcom G4 PLATINUM

System is used exceeds the applicable RF compliance level above, the

Dexcom G4 PLATINUM System should be observed to verify normal

operation. If abnormal performance is observed, additional measures may

be necessary, such as reorienting or relocating the Dexcom G4 PLATINUM

System.

b. Over the frequency range 150 kHz to 80 MHz, field strengths should be

less than 3 V/m.

Recommended Separation Distances Between Portable and
Mobile RF Communications Equipment and the Cradle

The Cradler is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
Cradle can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the Cradle as recommended below, according
to the maximum output power of the communications equipment. Portable
and mobile RF equipment include: baby monitors,
wireless routers, microwave ovens, laptops with internal Wi-Fi adapters, GSM
cell phones, RFID scanners and hand-held security metal detector often used
by security screeners.
