Step 6
Calibrating
You need to use your blood glucose meter to calibrate your Dexcom G4
PLATINUM System. At the end of the 2-hour startup period, you must enter
two calibrations before any sensor glucose readings will show. Calibration
blood glucose values need to be entered into the receiver within 5 minutes of
testing with your blood glucose meter.
Startup Calibration:
a. After the 2-hour startup period, the startup calibration
double blood drop prompt will show on the receiver
screen. Press the SELECT button to clear this alert.
b. Wash and dry your hands.
c. Take a fingerstick blood glucose measurement using your
Startup calibration
blood glucose meter.
prompt
d. From any trend graph, press the SELECT button to get
to the Main Menu.
e. Press the DOWN button to highlight Enter BG. Press the SELECT button.
f. For the startup calibration, the default blood glucose value on the receiver
is 120 mg/dL. Press the UP or DOWN button to enter the exact blood
glucose value from your blood glucose meter. Press the SELECT button.
g. Press the SELECT button again to accept the calibration.
h. Repeat steps c-g to enter a second blood glucose value.
Calibration Update:
The calibration single blood drop prompt will appear on
the receiver screen to let you know a calibration update is
needed. To confirm this prompt, press SELECT.
After your startup calibration, calibration updates must be
entered once every 12 hours at a minimum.
Calibration prompt
NOTE: Calibrating less than the recommended amount
may result in inaccurate sensor glucose readings. You
can enter more calibrations each day if you want. See the
Dexcom G4 PLATINUM System User's Guide for more
details on calibrating.
Step 7
Ending Your Sensor Session
The sensor automatically shuts off after 7 days.
The receiver will alert you at 6 hours, 2 hours and
30 minutes before the sensor session ends. The
Replace Sensor Now screen will show when it is
time to remove your sensor.

Removing Your Sensor Pod and Transmitter:
NOTE: Keep the sensor and transmitter together when removing from your
skin.
a. Peel the sensor pod off your body like a Band-Aid. Do not remove the
transmitter from the sensor pod until the entire sensor has been removed
from your body.
b. Place the sensor pod/transmitter on a flat
Safety
surface. There are two ways you can remove the
Lock
transmitter:
• Use your fingers to spread the back tabs of the
sensor pod. The transmitter will pop out.
OR
• Use the safety lock (from the sensor
applicator). Insert the jagged edges of the
safety lock so they "hug" the wide end of the
transmitter in the sensor pod. Press the safety
lock down until you cannot press anymore, and
then pull up. The transmitter will pop out.
c. Keep the transmitter. Dispose of the sensor

Calibration "Do's"
• Use the same blood glucose meter for all calibrations during a sensor
session.
• Make sure your blood glucose test strips are coded correctly and not
expired.
• Wash and dry your hands before testing your blood glucose.
• Use only fingerstick blood glucose values for calibration.
Calibration "Don'ts"
• Don't calibrate when you see or in the status bar.
• Don't calibrate if your blood glucose value is higher than 400 mg/dL or lower
than 40 mg/dL.
• Don't calibrate when acetaminophen (paracetamol) is active in your body.
Low Glucose Alarm
The Dexcom G4 PLATINUM System has an automatic Low Glucose alarm
set at 55 mg/dL. You cannot change or turn off this alarm or its re-alert
settings. If you get this alarm:
• Press the SELECT button to clear.
• You will get this alarm again in 30 minutes if your sensor
glucose reading is still at or below 55 mg/dL.

Advanced Features of the Dexcom G4 PLATINUM
CGM System
The Dexcom G4 PLATINUM System has advanced features and alerts to
take your glucose sensing to the next level. Except for the Trend Arrows and
Event Markers, these advanced alerts are turned 'off' when you first receive
your Dexcom G4 PLATINUM System but can be turned on and customized.
Advanced Feature #1: Trend Arrows
A trend arrow may show next to the sensor
glucose reading on your receiver trend screens.
Trend arrows show you the direction and speed
your glucose is changing. See the Dexcom
G4 PLATINUM System User's Guide for more
information.

alcohol). Event markers do not show on the receiver but can be downloaded
to the Dexcom Studio software. See the Dexcom G4 PLATINUM System
User's Guide for more information.

Frequently Asked Questions
What are the contraindications for the Dexcom G4 PLATINUM Sensor?
• The blood glucose value from your blood glucose meter should be used
for treatment decisions, such as how much insulin you should take. The
Dexcom G4 PLATINUM System does not replace a blood glucose meter.
• The Dexcom G4 PLATINUM Sensor, Transmitter, and Receiver must
be removed prior to Magnetic Resonance Imaging (MRI), CT scan, or
diathermy treatment. The Dexcom G4 PLATINUM System has not been
tested during MRI or CT scans or with diathermy treatment, and it is
unknown if there are safety or performance issues.
• Taking acetaminophen (paracetamol) containing products (such as Tylenol)
while wearing the sensor may falsely raise your sensor glucose readings.
The level of inaccuracy depends on the amount of acetaminophen
(paracetamol) active in your body.
Should I make treatment decisions based on the results from my
Dexcom G4 PLATINUM CGM System?
No. Treatment or insulin dosing decisions should be based on the blood
glucose value from your blood glucose meter. The direction, rate of glucose
change, and trend graph on your Dexcom G4 PLATINUM System provide
additional information to help with these decisions.
Is it okay if my Dexcom G4 PLATINUM CGM Sensor glucose readings
and fingerstick blood glucose values don't match exactly?
Yes. Your sensor glucose readings are meant to be used for trending only.
Your blood glucose meter and sensor measure your glucose from two
different types of body fluids: blood and interstitial fluid. Therefore, the values
from your blood glucose meter and sensor may not match exactly.
Why can't I take any acetaminophen (paracetamol) containing
medication while I am using the Dexcom G4 PLATINUM System?
Acetaminophen (paracetamol) is a contraindication of the Dexcom G4
PLATINUM System and should not be taken while your sensor is inserted.
The Dexcom G4 PLATINUM System may read inaccurately high when you
take acetaminophen (paracetamol)-containing drugs. The level and duration
of inaccuracy may be different for each person. To understand how long
acetaminophen (paracetamol)-containing medicines may affect your body,
consult your health care provider.
