WARNING: The Threshold Suspend feature will cause the pump to temporarily suspend insulin delivery for two hours when the sensor glucose reaches
a set threshold. Under some conditions of use the pump can suspend again
resulting in very limited insuln delivery. Prolonged suspension can increase
the risk of serious hyperglycemia, ketosis, and ketoacidosis. Before using the
Threshold Suspend feature, it is important to read the Threshold Suspend
information in this Getting Started Guide and the MiniMed 530G` System
User Guide and discuss proper use of the Threshold Suspend feature with
your healthcare provider.
Record safety information from your healthcare provider:

Sensor Glucose and Blood Glucose
Section 2:Sensor Glucose and Blood Glucose
Your BG meter measures glucose levels in your blood while your glucose sensor measures glucose in
the uid surrounding the cells of your tissue. This uid is called interstitial uid.
Most of the time, glucose travels to your blood rst and then to your interstitial uid. Because of how
glucose moves, your BG meter readings and your sensor glucose readings will rarely match exactly
but should be close. This dierence is normal and should be expected.
However, when glucose levels are rising or falling quickly, you should expect to see a larger difference
between your BG meter readings and the sensor glucose readings. Examples of times when this larger
dierence may occur include:
• When or arrows appear on your pump screen
• After meals or after taking a bolus of insulin
IMPORTANT Sensor glucose is not the same as blood glucose. Your sensor glucose reading will
rarely match your BG meter reading.
Sensor glucose values should not be used to make diabetes treatment decisions. Always conrm
your blood glucose with a BG meter rst.
If you “feel” that your glucose is high or low, but your sensor glucose does not match your
symptoms, always test your blood glucose using your BG meter.

Trends
Section 3:Trends
When using CGM focus on what matters, the trends - the direction and the speed of the sensor glucose
readings and graphs. Pay less attention to each individual glucose number.
Example of a Sensor Glucose Trend Graph
Sensor Glucose Graph
Trend Arrow
Sensor Glucose
Reading
Your insulin pump screen will display 3-hour, 6-hour, 12-hour, and 24-hour glucose trend graphs. The
most current part of the graph appears on the far right side of the graph display.
There are times you may see one or two arrows next to your sensor glucose reading. Arrows indicate that
your sensor glucose has been changing rapidly:
or means your glucose has risen or fallen by 2 or more mg/dL per minute
or means your glucose has risen or fallen by 1-2 mg/dL per minute
When might you see your glucose trending up or down?
You may notice that after eating, giving a bolus, or when
exercising your glucose may begin to rise or fall.

Section 4:Personalize Alarm and Alerts
Your CGM settings will be most benecial to you if they are personalized for your needs. Personalizing
alerts means that all or some settings will be programmed during your CGM training but can be changed
to better meet your needs as you learn more about the information your CGM provides. Your healthcare
provider will work with you and your trainer to determine your initial settings and help with adjustments.
There are ve main categories of alarm and alerts that you can personalize:
• High and Low Glucose Alerts
• Predictive Alerts
• Rate of Change Alerts
• Threshold Suspend Alarm
• Calibration Alerts
Low and High Glucose Alerts
Low and high glucose alerts notify you when your sensor glucose readings have reached or moved
below or above your programmed glucose limits. You can set up to eight customizable Low and High Glucose Limits for dierent periods of the day or night. You may set either the low or high limit or both.
The Low Glucose Limit can be set from 40 to 390 mg/dL. The High Glucose Limit can be set from 50 to
400 mg/dL.
In order to temporarily silence or “snooze” repeated glucose alerts, the High and Low Repeat are set for
the amount of time when you are reminded that your sensor glucose is still above or below your selected
glucose limits. The Low Repeat can be set from 5 minutes to 1 hour. The High Repeat can be set from 5
minutes to 3 hours. High and Low Repeat will also apply to other CGM settings (Rate of Change and Predictive Alerts and Threshold Suspend alarm which are discussed next).
While sleeping...
Michael wants his CGM to alert him if his sensor glucose falls too low
so his doctor instructed him to set his Low Glucose Limit to 80 mg/
dL and leave his High Glucose Limit o to prevent too many alerts.
During the day when he’s awake his Low Glucose Limit is set to 70
mg/dL as he is able to sense when his glucose is low. Michael and his
doctor agree that these settings work best for him.
Low Glucose Limit and Threshold Suspend may be programmed at the same or dierent settings.

Predictive Alerts
Predictive Alerts can warn you up to a half hour before you reach your chosen High or Low Glucose Limit.
With Predictive Alerts you can be made aware of potential highs and lows even before they occur. You
may set a Predictive Low, Predictive High, both or neither. The Predictive Alerts can be set from 5 to 30
minutes.

Rate of Change Alerts
Rate of Change Alerts tell you when your glucose is changing rapidly. These alerts are useful for
understanding how quickly your glucose levels are aected by meals, insulin, and physical activity (such
as forgetting to bolus or giving yourself more insulin than you needed) and to recognize potentially
dangerous sensor glucose changes before they become a problem. You can set a Fall Rate, Rise Rate, both
or neither. The Rate of Change Alerts can be set from 1.1 to 5.0 mg/dL/minute.
NOTE: Your healthcare provider may determine that using the Rate of Change Alerts are
more helpful when notifying you of extreme changes in your sensor glucose. Otherwise,
setting the rate too low may cause you to receive too many alerts when you may not need
them such as after every time you eat causing your sensor glucose values to rise quickly.
While exercising…
Mark sometimes experiences low glucose when he is playing tennis.
His doctor has determined that using the Rate of Change Alert may
be helpful. His doctor has instructed him to set his Fall Rate to 4 mg/
dL/minute. Now when his pump noties him that his sensor glucose is
falling rapidly and is also trending towards his Low Glucose Limit of 70
mg/dL Mark is prepared to take action sooner.

Threshold Suspend
The Threshold Suspend feature stops the pump’s insulin delivery if your sensor reading has reached or
fallen below your programmed suspend threshold. Threshold Suspend can be set from 60 to 90 mg/dL.
WARNING: Threshold Suspend is not intended to be used to prevent or treat low glucose. Always conrm
your blood glucose using your BG meter. Treat a conrmed low blood glucose with carbohydrates and
according to your healthcare provider’s instructions. If you are unable to respond to the Threshold Suspend
alarm, insulin delivery will remain suspended for 2 hours unless you restart basal insulin delivery earlier.
Once the Threshold Suspend alarm is triggered, all insulin delivery will stop immediately and the pump will
siren. The pump will continue to siren until the alarm is cleared by pressing
ESC
, followed by
After clearing the alarm you will have the option to continue to suspend or restart basal insulin delivery.
If you do not clear the alarm:
- insulin delivery will remain suspended for 2 hours
- then basal insulin will restart automatically for 4 hours regardless of the sensor glucose value
- NOTE: Your standard basal rate or basal pattern will restart. Any programmed temporary basal will
be cancelled.
ACT
.
NOTE: Any bolus that was delivering at the time of Threshold Suspend will not restart.
If you clear the alarm within 2 hours:
- you will have the option to continue to Suspend or Restart Basal insulin delivery
- if you choose to continue to suspend, the pump will remain suspended for 2 hours before restarting basal insulin
- once basal insulin is restarted, the pump will use the Low Repeat time that is set as the time frame to suspend again if the sensor glucose is still at or below the Suspend Threshold
- Any bolus that is delivering at the time of Threshold Suspend will not restart
- NOTE: If a temporary basal is delivering at the time of Threshold Suspend, then it will restart.
While sleeping…
Beth has set the Threshold Suspend feature to siren at a sensor
glucose value of 60 mg/dL or below. If the siren awakens her she can
check her glucose with her BG meter. If her BG is conrmed to be
low, Beth will follow the recommendations of her healthcare provider
to treat low blood glucose. Beth knows that if she is ever unable to
respond to the Threshold Suspend siren, the pump will automatically
suspend insulin delivery for 2 hours.
WARNING: Threshold Suspend uses the sensor glucose value, not the blood glucose value, to
automatically suspend all insulin delivery. Be aware that your pump may automatically suspend when your
sensor glucose is at or below the Suspend Threshold but while your blood glucose is above that threshold.
This could result in hyperglycemia. Likewise, your pump may not suspend even when your blood glucose
is at or below the Suspend Threshold. This could result in hypoglycemia. Always conrm your blood
glucose using your BG meter and treat as directed by your healthcare provider.

Calibration Alerts
Calibration alerts remind you when a sensor calibration (“Meter BG Now” alert) is due. There are two
types of calibration alerts. The Cal Repeat is the amount of time after a missed calibration when you are
reminded that a calibration is needed. You can set your Cal Repeat from 5 minutes to 1 hour. The other
is the Cal Reminder which is the amount of time until your next calibration is required. The Calibration
Reminder is optional and can be set from 5 minutes to 6 hours.
To reduce inconvenient alerts…

2. Important:
Attach the overtape
to both the rounded
part of the sensor
and the skin in front
of the sensor.
5. This image is an
example of the overtape applied correctly.
u
3. Stretch the remaining
part of the overtape around
the sensor connector so
that the tape sticks to the
curved adhesive pad and
does not block the sensor
connector. Press the
overtape to your skin
for several seconds to
help ensure that it sticks
securely.
IMPORTANT
All Enlite tapes
and adhesives
stick best when you apply
pressure for several seconds
after putting them on your
skin. Doing so helps the Enlite
sensor stay securely placed
and fully inserted.
20
Page 23
Sensor Insertion
Properly applying the overtape is key to ensuring your success with the Enlite sensor.
Due to the sensor’s small size and flexible nature, the overtape helps to secure it from
body motion or physical activity that can cause it to be pulled out.
Checking Proper Tape Application
It is important to check your sensor site periodically to make sure the sensor is still secure and has not
been pulled out. If the sensor has been pulled out, do not try to push it back into place as this will
damage the sensor.

Calibration
Section 6:Calibration
Your continuous glucose monitoring system requires BG meter readings in order to generate sensor
glucose readings. These BG meter readings are entered into the pump and are for sensor calibrations.
Calibration is essential for optimal CGM performance. CGM does not eliminate the need for BG meter
readings.
To calibrate, you must use a fingerstick blood sample to test your BG on your meter and then enter that
value into your pump. The pump will accept BG meter readings between 40 mg/dL to 400 mg/dL.
After inserting a new sensor, a calibration is needed:
• Approximately 2 hours after you connect the transmitter to your sensor and initialize your sensor.
Your pump will notify you with a “METER BG NOW” alert when it is ready for its rst calibration.
• Again within 6 hours (rst day of inserting sensor only)
• Again every 12 hours
The minimum number of calibrations required is once every 12 hours (after the rst day). The sensor’s
accuracy can be improved with 3 - 4 calibrations per day. *Although not optimal, calibrations can be
done at anytime providing you with the exibility to calibrate at times that are convenient for you
and to avoid needing to calibrate when it is less convenient such as during the night.
*Note: Calibrating with
or
displayed on the CGM screen may decrease sensor accuracy until the
next calibration.
Calibrations are necessary in order to continue to receive sensor
glucose readings, alerts, and Threshold Suspend alarms. Not
calibrating properly can aect CGM performance.
Approximately two hours after inserting a new sensor, a “METER BG NOW” alert will notify you that the
pump is ready for your rst calibration. Clear the alert by pressing
ESC
, followed by
ACT
and follow these
steps:
There are two ways to calibrate:

transmitter are connected and your sensor is ready for its rst calibration).
Calibrating through your Sensor Menu can only occur if
your pump’s insulin delivery is not suspended.
After your rst calibration, it will take about 10-15 minutes for sensor glucose readings to appear on your
pump screen. To nd when your next calibration is due press

Calibrate before bed…
Pam knows she will not have to wake up in the middle of the night
from a “METER BG NOW” alert if she tests her BG before bed and
enters that value into her pump to calibrate her sensor.
IMPORTANT If you notice a large dierence between your BG meter reading and
sensor glucose readings, do another BG ngerstick test after washing your hands. Then
check the sensor site to ensure the sensor is still inserted in your skin. If there is still a
large dierence in glucose readings, then another calibration may be needed to bring the readings closer together again. Wait 15 minutes before entering another BG
reading for a calibration.

What the Sensor Connection Icons Mean
Insulin pump indicates that the MiniLink® transmitter and insulin
pump/CGM monitor are communicating properly.
Pump/CGM monitor has not received a signal for more than 5–7 minutes. This
is okay. The MiniLink transmitter stores up to 40 minutes of data and will send
these readings to the insulin pump once a signal is re-established.

CareLink® Personal Software
Section 7:CareLink® Personal Software
CareLink Personal software is a free, web-based program that allows you to upload information from your
insulin pump, CGM, and blood glucose meter, making it easier to understand your glucose patterns and
trends.
CareLink Personal is an important part of your success with CGM as it will assist you and your healthcare provider in tracking your glucose levels to see how they are aected by your insulin delivery, meals,
and exercise routines. It provides you with a secure place to store your information and uncover glucose
patterns that meter and logbooks alone cannot reveal. It also allows you and your healthcare provider
to make more informed therapy decisions such as identifying which pump settings to change for better
glucose control.
CareLink organizes your sensor and meter glucose readings, insulin usage, and carbohydrate intake into
detailed reports with charts, tables, and graphs.
Tips for Using CareLink Personal
• Regularly upload your insulin pump using CareLink Personal (at least once/month)
• Review your data and look for patterns and trends
• Discuss therapy adjustments with your healthcare provider

Charging and Storing the MiniLink® transmitter
Charge the transmitter before each use. When the transmitter is
charging, a green light will ash on the charger. This green light
on the charger will turn o when the transmitter is completely
charged. A completely depleted transmitter battery will need
up to 8 hours to recharge. The transmitter can be used for a
maximum of 6 full days in between charges.
When you remove the transmitter from the charger, a green
light should ash on the transmitter. This indicates that it has
enough battery power and is ready to be connected to the sensor.
If you do not see the green ashing light on the transmitter place
it back on the charger until it is fully charged.
Store the transmitter, charger, and test plug in a clean, dry location
at room temperature. Although not required, you may store the
transmitter on the charger. If the transmitter is not in use, you
must charge it at least once every 60 days.
If you see red lights on the charger that ash once every 2 seconds, then the AAA
battery in the charger needs replacement. However, if you see a mix of quick and long
ashes of red lights, then the transmitter battery is depleted and should be fully charged.
Note: Refer to your MiniLink® transmitter User Guide for more information.

Going for X-rays, MRI, or CT Scan
If you are going to have an X-ray, MRI, CT scan, or other type of diagnostic imaging involving radiation exposure, remove your insulin
pump, transmitter, and glucose sensor and place them outside of
the testing area.
Appendix
Going through Airport Security
Your monitor should not go through the x-ray machine that is used
for carry-on or checked luggage. The full body scanner is also a
form of x-ray. If you choose to go through the full body scanner,
you will need to remove your sensor and transmitter prior to the
scan. To avoid removing your devices, you should request an
alternative screening process that does not use x-ray. Your CGM
system (monitor, sensor, and transmitter) can withstand exposure
to metal detectors and wands used at airport security checkpoints.
Traveling by Air
Your transmitter, sensor, and insulin pump are safe for use on U.S.
commercial airlines and can be worn during ight. However, if airport security requests that you turn o your CGM device, then you
must comply. It is advisable to check with the Transportation Safety
Administration (TSA) for updates. International passengers should
consult with their individual air carriers for international regulations.
To turn o your CGM, simply:
1) Go to: Home Screen > Main Menu > Sensor >
X
X
Turn O Sensor
2) Keep the glucose sensor in place on your body, but
disconnect the transmitter from the sensor and store
it on the charger.
To turn on your CGM after the ight:
1) Reconnect your transmitter to your sensor
2) Go to: Home Screen > Main Menu > Sensor > Edit
Settings > Sensor: On
3) Go to: Home Screen > Main Menu > Sensor > Link to
Sensor > Reconnect Old Sensor
In two hours you will be prompted by a “METER BG NOW” alert that
a calibration is needed.
NOTE: It is important that
you test your blood glucose
(BG) more frequently while
you are traveling. The routine hassle of travel, including stress, changes in time
zones, schedules and activity levels, meal times and
types of food, can all aect
your diabetes control. Be
extra attentive to monitoring your BG frequently, and
be prepared to respond if
needed.

Calibrate (You will
only see option to
Calibrate if sensor
and transmitter are
connected and sensor
is ready for rst calibration).
Note: Calibrating through Sensor Menu can only
occur if pump’s insulin delivery is not suspended.
Stops all insulin delivery when your sensor glucose reading has reached or fallen below your
programmed Suspend Threshold (can be set between 60 – 90 mg/dL).
Important Tips:
• Threshold Suspend is not intended to be used to treat or
prevent low blood glucose. Conrm your blood glucose using
your BG meter. Then treat your conrmed low blood glucose using
the “15-15 Rule” or as directed by your healthcare provider:
- Take 15 grams of fast-acting carbohydrates (4 oz. orange
juice, 3-4 glucose tabs) and wait 15 minutes. Then retest your
blood glucose. If your blood glucose has not improved, then
take another 15 grams of carbohydrates, wait 15 minutes,
and retest.
• Do not miss Calibrations. Threshold Suspend requires that CGM is
working. Calibrate before going to bed.
• Avoid “Lost Sensor” alert. Check that your sensor has not pulled out of your skin. Check that your transmitter and sensor are properly
connected and communicating with your pump.
• Check the battery. Change the pump battery when you receive a
“Low Battery” alert to avoid depleting the battery quickly during
Threshold Suspend.
• Avoid nuisance alarms with the two-step response to the
Threshold Suspend siren:
- First, clear the alarm (press
ESC
, followed by
ACT
)
- Then, select continue to “Suspend” or “Restart Basal” delivery
