Notes on disposal
The symbol of the crossed-out wheeled bin on the product, The symbol of the crossed-out dumpster on the product, the (rechargeable) battery (if applicable), and/or the packaging indicates that these products must not be disposed of with normal household waste, but must be disposed of separately at the end of their service life. For the packaging, follow the regulations in your country for separating waste. Improper disposal of packaging materials can be harmful to your health and the environment.
The separate collection of waste electrical and electronic equipment, (rechargeable) batteries (if applicable), and packaging is intended to promote reuse and recycling and to prevent negative impacts on public health and the environment, for example, due to hazardous substances contained in these products. At the end of their service life, recycle electrical and electronic equipment and (rechargeable) batteries so that their materials can be reused and prevent environmental pollution.
If (rechargeable) batteries can be removed without destroying them, you are obliged to dispose of them separately (see the product’s operating instructions for information on how to remove the batteries safely). Be especially careful when handling (rechargeable) batteries containing lithium, as these pose special hazards, such as the risk of fire and/or health risks if button cells are swallowed. Reduce battery waste as much as possible by using longer-life batteries or rechargeable batteries.
Further information on the recycling of these products can be obtained from your municipal administration, from the municipal collection points, or from your Sennheiser partner. You may also be able to return electrical or electronic equipment to your distributor if they are legally required to do so. By disposing of your batteries properly, you are helping to protect public health and the environment.
