Important Safety Information
Regarding Your Insulin Pump (includes all models)
Avoid Immersing Your Pump In Water
The pump was tested and met requirements for IPX7 at time of manufacture. For
more information about IPX7, see the Glossary on page 273. Be aware that drops
and bumps that occur over time will affect the integrity of the pump case and
make it more vulnerable to damage from water. Lotions, sunscreens and insect
repellent can also damage the pump case. It is not known how much water is
needed to damage your pump. You should avoid getting your pump wet. To
shower, bathe, swim, or participate in water activities, always disconnect from
your pump and reconnect after you are out of the water.
If you inadvertently submerge your pump in water, dry the pump quickly using a
soft, clean towel and verify that it is working properly by selecting Selftest from
the pump's Utilities Menu. If you believe that water has entered your pump or you
observe any other possible pump malfunction, please check your blood glucose,
treat high blood glucose (if necessary) with an injection and contact our 24 Hour
HelpLine at 1 800 646 4633 for further assistance. Symptoms of high blood glucose
include fatigue, excessive thirst and nausea. Always contact your healthcare
professional if you experience excessively high or low blood glucose levels, or if
you have any questions about your care.
Important safety information is continued on the next page.
Although your pump is designed to be unaffected by typical levels of electrostatic
discharge (ESD), very high levels of ESD can result in a reset of the pump's
software with an associated pump error alarm. In most cases, exposure to high
levels of ESD will trigger the pump's A-13 alarm although, under certain
circumstances, high level ESD exposure can cause A-44, Bolus Stopped or Max
Delivery alarms. High levels of ESD are more likely in situations where the relative
humidity is very low, such as inside a heated building during the winter in areas
where it is cold outside.
If your pump experiences an A-13 or other error alarm, press the ESC and ACT
buttons to clear the alarm. If you are unable to clear the alarm by pressing ESC
and ACT, you may need to remove and replace the pump's battery to clear the
alarm. After clearing the alarm, you should always verify that your pump is set to
the correct date and time and that all other settings (basal rate, max basal and
bolus limits, etc.) are programmed to the desired values, since the software reset
could erase your previously programmed settings. Please see Alarms and alerts, on
page 201 for more details regarding what to do if your pump displays an error
alarm or other alert message.
Please contact our 24 Hour HelpLine at 1 800 646 4633 to report any error alarms or
other problems that occur with your pump.
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 insulin 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
the Getting Started Guide and the MiniMed 530G System User Guide
and discuss proper use of the Threshold Suspend feature with your

Keep an emergency kit with you at all times to make sure that you always have
necessary supplies. Inform a family member, co-worker, or friend where this
emergency kit is kept. Please refer to the User safety section in this chapter for
more information on pump safety. 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 affect your diabetes control. Be extra attentive to monitoring your
BG frequently, and be prepared to respond if needed. Your emergency kit should
include these items:
Fast-acting glucose tablets
Blood glucose monitoring supplies
Urine ketone monitoring supplies
Extra MiniMed infusion set and MiniMed reservoir
Insulin syringe and fast-acting insulin (with dosage instructions from your
Dressing and adhesive
Glucagon Emergency Kit®

WARNING: Do not use the Bolus Wizard to calculate a bolus for a
period of time after giving a manual injection by syringe or pen.
The Bolus Wizard does not account for manual injections, and could
prompt you to deliver more insulin than needed. Too much insulin
may cause hypoglycemia. Consult with your healthcare professional
for how long you need to wait after a manual injection before you
can rely on the active insulin calculation of your Bolus Wizard.
The pumps use MiniMed disposable reservoirs and infusion sets for insulin delivery.
Installation instructions for MiniMed reservoir and infusion sets are provided in the
Starting on insulin chapter.
Infusion sets — Medtronic Diabetes provides a variety of infusion sets to fit
your needs. Contact your healthcare professional for help in choosing an
infusion set that fits your needs. Change your infusion set every two to three
days per your infusion set manufacturer's instructions.
Reservoirs — Only use Medtronic Diabetes custom-made reservoirs in the
MiniMed 530G system. Look on the back of your pump for your model
number. For the MMT-551 pump model, use the MMT-326A, 1.8 ml (180-unit)
reservoir. The MMT-751 pump model can be used with either the MMT-332A,
3.0 ml (300-unit) reservoir or the MMT-326A, 1.8 ml (180-unit) reservoir,
