5.3.2 Battery Disposal
You must always return old batteries to a dealer or to a returns depot set up for this
purpose by the public waste disposal body or a licensed battery dealer for recycling.
Only dispose of dead batteries in public or commercial collection boxes. The battery
is drained when the message „Change battery“ appears on the display of the device.
To prevent short circuitry in the collection boxes, insulate the poles of each battery
with insulation tape or put each single battery into a plastic bag.
