Install battery
CAUTION: Do not use a rechargeable or carbon zinc battery in your pump. For best results use a new
Energizer AAA alkaline battery, size E92, type LR03.
Medtronic Diabetes designed the pump to only accept a NEW battery. As a safety measure, if you install a
battery that does not have full power, the WEAK BATTERY or FAILED BATT TEST alarm may sound. If you
receive a WEAK BATTERY alarm, respond to the alarm and continue. The pump will still operate normally,
but with a decreased battery life. The pump uses one AAA alkaline battery.
1 Make sure all the following apply:
•Clear (ESC, ACT) any alarms and/or alerts before removing and replacing the battery
• Make sure the pump is at the HOME (idle) screen when you remove the battery.
• Do NOT remove the battery during a bolus or prime delivery.
2 Use the edge of a coin to remove the battery cap. Turn the cap in a counter-clockwise direction.
3 Remove the old battery and dispose of it per
the disposable requirements of your state or
country. Put the new battery in the pump with
the negative end [(-) symbol] going in first.
Check the label on the back of the pump to
make sure the battery is inserted correctly.
NOTE: Do not use batteries that have been in
cold storage (i.e., in the refrigerator or your car in the winter).
4 Place the battery cap in the pump and tighten so the
slot is aligned horizontally with the pump as shown
here:
CAUTION: Do NOT over-tighten the battery cap. You
should not turn the cap more than four half turns. If
you over-tighten the cap you may not be able to
remove it, and you can damage your pump.
