Battery notices
The device associated with this operating manual contains 2 AAA Alkaline batteries (1.5 V) in
delivery condition. These batteries are not made for recharging. The use of a rechargeable
battery is not possible with this device and can damage it. If the included batteries are deple-
ted, they must not be thrown into the household waste. Used batteries may contain harmful
substances that can cause environmental or health damage. Please return all depleted
batteries to electrical appliance stores, who collect them for free.
Battery exchange

push down and away from the unit to release the cover. See the following diagram.
Attention: Mind the battery polarity in the process (+/-).
In the EU the return of used batteries is mandatory by law. All depleted batteries and also
rechargeable batteries will be recycled. This way valuable resources like iron, zinc and nickel
can be retrieved and are reusable then. Battery recycling is the easiest lesson in environmen-
tal protection – so please support it!
