The symbol may also be marked on the product.
Environmental Protection
BERNINA International AG is committed to environmental protection. We strive to minimize the
environmental impact of our products by continuously improving product design and our technology of
manufacturing.
The machine is labeled with the symbol of the crossed-out wastebin. This means that the machine should
not be disposed of in household waste when it is no longer needed. Improper disposal can result in
dangerous substances getting into the groundwater and thus into our food chain, damaging our health.
The machine must be returned free of charge to a nearby collection point for waste electrical and electronic
equipment or to a collection point for the reuse of the machine. Information on the collection points can be
obtained from your local administration. When purchasing a new machine, the dealer is obliged to take back
the old machine free of charge and dispose of it properly.
If the machine contains personal data, you are responsible for deleting the data yourself before returning the
