7 Insert the screwdriver between the bottom of the
battery and the black frame to break the metal tab
connecting the battery to the green printed circuit

from the frame.

components to break the second metal battery tab.
Caution: Be aware of the sharp edges of the
battery tabs so as to avoid injury to your fingers.

electrical short from residual battery charge.
The rechargeable battery can now be recycled and
the rest of the product discarded appropriately.
Note: Do not throw away the appliance with the normal
household waste at the end of its life, but hand it in at an
official collection point for recycling. By doing this, you
help to preserve the environment.
