Install battery
Medtronic MiniMed designed the pump to only accept a NEW battery. As a safety measure, if you install a bat-
tery that does not have full power, the “failed batt test” alarm will sound. The pump uses one AAA alkaline bat-
tery.
1. Use the edge of a quarter to remove the battery cap. Turn the cap in a counter-clockwise direction.
2. Put the 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).
3. Place the battery cap on the pump so that the
slot is aligned in the orientation shown here:
4. Turn the battery cap clockwise 4 half-turns so the slot
is aligned horizontally with the pump as shown here:
Do NOT apply force when you turn the cap.
CAUTION: Do not use a rechargeable or carbon zinc battery in your pump. A new AAA Alkaline Ener-
gizer battery is strongly recommended. The use of any other battery type may not offer
the same battery performance.
CAUTION: Do NOT over-tighten the battery cap.
You should not turn the cap more than four
(4) half-turns. If you over-tighten the cap
you may not be able to remove it, and you
can damage your pump.
Align the cap slot
horizontally with
the pump.
