GLOSSARY
Alternative Site
BG Testing
This is when you take a blood glucose value on your meter
using a blood sample from an area on your body other than
your ngertip. Do not use alternative site testing to calibrate
your receiver.
Applicator A disposable piece that comes attached to the sensor pod and
inserts the sensor under the skin. There is a needle inside the
applicator that you remove after you insert the sensor.
BG Meter Blood glucose meter. A device used to measure how much
glucose is in the blood. You can use any commercially available
meter for testing your blood glucose.
BG Value Blood glucose value. The measurement of glucose in the blood.
A blood glucose value taken with your commercially available
blood glucose meter.
Bluetooth®Bluetooth wireless technology allows devices to wirelessly
communicate with each other. In this case, communication
between the receiver and your iPhone®/iPod touch® device.
Calibration When you enter blood glucose values from a blood glucose
meter into the receiver. Calibrations are needed for your
receiver to show continuous sensor glucose readings and trend
information. (Do not use alternative site testing for calibration).

Commercially
Available
Product that may be sold in the United States.
Default A setting that is selected automatically, unless you choose
another option.

Dexcom
Share™System
Secondary notication system to the Dexcom G4 PLATINUM
System. For more information, please refer to the Dexcom
Share User Manual.
Glucose Data
Gaps
Different symbols show on the trend graph instead of a sensor
glucose reading to let you know that the receiver cannot
provide a reading.
Glucose
Trends
Trends let you see the pattern of your glucose levels. The trend
graph shows where your glucose levels have been during
the time shown on the screen and where your glucose levels
are now.
Hypoglycemia Low blood glucose. Same as “low.” The default low alert in
your receiver is set to 80 mg/dL. Consult your healthcare
professional to determine the appropriate hypoglycemic setting
for you.
Hyperglycemia High blood glucose. Same as “high.” The default high alert
in your receiver is set to 200 mg/dL. Consult your healthcare
professional to determine the appropriate hyperglycemic setting
for you.
HypoRepeat Optional receiver alert setting that keeps repeating the xed
low alarm every 5 seconds until your sensor glucose reading
rises above 55 mg/dL or you conrm it. This prole can be
helpful if you want extra awareness for severe lows.
mg/dL Milligrams per deciliter. The standard unit of measure for sensor
glucose readings in the United States.

GLOSSARY (continued from page before)
Obstruction Something that blocks the wireless path between the
transmitter and receiver. There are many types of things that
could come between the transmitter and receiver, and Dexcom
could not test them all. “Without obstruction” means that we
have not tested whether items blocking the transmitter or
receiver could affect the transmission range.
Proles Sound pattern and volume level settings for your alerts.
Range The distance between the receiver and transmitter. Keep the
two devices within 20 feet of each other without obstruction to
get glucose information on your receiver.
Re-Alert A re-alert happens after the rst alert is not conrmed.
Receiver The small device that collects your glucose information from the
sensor/transmitter. Your results show on the receiver screen as
a sensor glucose reading (mg/dL) and as a trend.
Rise and Fall
(Rate of
Change) Alerts
Alerts based on how fast and how much your glucose levels
rise/fall.
RF Radio-frequency transmission used to send glucose information
from the transmitter to the receiver.
Safety Lock The safety lock keeps the needle inside the applicator
before you are ready to insert the sensor. It also helps you
snap the transmitter out of the sensor pod after your sensor
session ends.

GLOSSARY (continued from page before)
Sensor The Dexcom G4 PLATINUM (Pediatric) System part that
includes an applicator and wire. The applicator inserts the wire
under your skin, and the wire measures glucose levels in your
tissue uid.
Sensor Pod The small plastic base of the sensor attached to your skin that
holds the transmitter in place.
Snoozing The option to delay your alert for a set amount of time. A
snooze time can be set for high and low glucose re-alerts.
Startup Period The 2-hour period after you tell the receiver you inserted a
new sensor. Sensor glucose readings are not provided during
this time.
System
Reading
A sensor glucose reading shown on your receiver. This reading
is in mg/dL units and is updated every 5 minutes.
Transmitter The Dexcom G4 PLATINUM (Pediatric) System part that snaps
into the sensor pod and wirelessly sends glucose information to
your receiver.
Transmitter ID A series of numbers and/or letters that you enter into your
receiver to let it communicate with the transmitter.
Transmitter
Latch
The small, disposable piece that snaps the transmitter into the
sensor pod. It is removed after the transmitter is snapped in.
Trend (Rate
of Change)
Arrows
Arrows on trend graphs that show how fast your glucose levels
are changing. There are 7 different arrows that show when your
glucose speed and direction change.

1.2 INTRODUCTION
When you use the system, you will see continuous sensor glucose
readings updated every 5 minutes for up to 7 days. These readings will
help you notice trends and patterns in your glucose levels.
The system includes the Dexcom G4 PLATINUM Sensor, the Dexcom
G4 PLATINUM Transmitter, and the Dexcom G4 PLATINUM (Pediatric)
Receiver with Share. The sensor is a disposable unit that you insert
under your skin to continuously monitor your glucose levels for up to 7
days. The transmitter is a reusable device that wirelessly sends your
sensor’s glucose information to your receiver. The receiver is a hand-held
device that receives and displays your glucose information.
Please read this user’s guide closely. It describes how to use
your system.
In addition, Dexcom®has a self-guided training tutorial for the Dexcom
G4 PLATINUM (Pediatric) CGM System. Some people have found
this to be an effective method of product training. Please review the
tutorial on the disc and discuss with your healthcare professional to
decide if the Dexcom G4 PLATINUM (Pediatric) System Tutorial is a
good training option for you. The tutorial disc can only be used with
your computer and cannot be used in DVD players. The tutorial is also
found on the Dexcom website – www.dexcom.com.

PRECAUTION
The Dexcom G4 PLATINUM Sensor, Transmitter, and
Receiver are not compatible with the SEVEN®/SEVEN®
PLUS Transmitter and Receiver. Different generations
will not connect with each other and will not work. Also,
make sure to use the correct version of Dexcom STUDIO
with your system.

1.3 SENSOR OVERVIEW
The sensor is the piece that comes in a sterile, sealed sensor pouch.
The sensor is made up of an applicator, a sensor pod, and a sensor
wire. You remove the applicator after insertion. The sensor pod stays on
your skin for the entire sensor session, up to 7 days. The pod is made of
plasticandanadhesivepatch.Thesensorwireisthinandexible,and
inserts just under your skin. It is attached to the sensor pod, and is made
of silver and platinum metal with polymer membranes. You discard the
sensor at the end of the session.

1.4 TRANSMITTER OVERVIEW
The transmitter is the gray, plastic “chip” that snaps into your sensor
pod. The 9438-01 transmitter (including sensor pod) is 1.5 inches long,
0.9 inches wide and 0.5 inches thick. The 9438-05 transmitter (including
sensor pod) is 1.5 inches long, 0.9 inches wide and 0.4 inches thick.
Once snapped into the sensor pod, the transmitter wirelessly sends your
glucose information to the receiver. The transmitter and sensor are water
resistant when properly connected. Do not throw away your transmitter.
It is reusable.
The transmission range from the transmitter to the receiver is up to 20
feet without obstruction. Wireless communication does not work well
through water, so the range is much less if you are in a pool, bathtub or
water bed.
The transmitter battery will last at least 6 months. Once you see the
transmitter low battery screen, replace the transmitter as soon as
possible. Your transmitter battery may drain as quickly as one week after
this alert appears.
