10 Disposal

CAUTION
Improper disposal of the equipment may have serious consequences: the burning of plastic components generates
toxic fumes which may present a health hazard. Batteries may explode if damaged or exposed to very high
temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal may permit
unauthorized and improper use of the equipment. This may result in serious personal injury, injury to third parties and
pollution of the environment.
CAUTION
Dispose of defective batteries without delay. Keep them out of reach of children. Do not attempt to open or dismantle
batteries and do not dispose of them by incineration.
