Prepare the pump for use
To prevent water from entering the casing, change the
battery only in a dry environment and make sure that
the seal is not worn out or missing and that the battery
is properly inserted. Tighten or loosen the battery cover
with the Accu-Chek Spirit battery key (use of knives,
screwdrivers or other sharp objects may harm your
insulin pump). Do not over-tighten as this may cause
damage to the battery cover and to the casing. The
battery cover is correctly inserted and tightened when
the battery cover is level with the insulin pump casing.
Your insulin pump is powered with a single 1.5 volt AA battery.
See chapter 4.3 "Battery" for more detailed information on recommended
batteries.

Caution
Make sure your insulin pump is in STOP and the
KeyLock is unlocked or turned off.
Remove or disconnect your infusion set from the
infusion site to ensure that no risk of insulin
delivery may occur.
