Your MITSUBISHI ELECTRIC product is designed and manufactured with high quality materials and components which can be
recycled and/or reused. This symbol means that electrical and electronic equipment, batteries and accumulators, at their end-of-life,
should be disposed of separately from your household waste. If a chemical symbol is printed beneath the symbol (Fig. 1), this chemi-
cal symbol means that the battery or accumulator contains a heavy metal at a certain concentration.
This will be indicated as follows: Hg: mercury (0.0005%), Cd: cadmium (0.002%), Pb: lead (0.004%)
In the European Union there are separate collection systems for used electrical and electronic products, batteries and accumulators.
