d) Operation
• Ensure that there is sufficient ventilation during operation. Never cover up the charger or the mains unit.
Leave enough of a distance (at least 20 cm) between charger and other objects. Overheating causes a
danger of fire!
• The charger may only be connected to a stabilised direct current voltage of 12 V/DC as voltage/current
supply (e.g. via the included mains unit).
• Do not operate the product unattended. Despite a considerable number of protective circuits, it is
impossible to exclude the possibility of malfunctions or problems during the charging process.
• Do not wear any metal or conductive materials, such as jewellery (necklaces, bracelets, rings, etc.) whi-
le you are working with the charger or batteries. Short-circuit poses a danger of burns and explosion.
• Never place metal lines and contacts between the rechargeable battery and the charging slot!
• The charger must only be used to charge (or discharge) rechargeable batteries of type NiMH, NiCd and
NiZn. Never insert any other rechargeable batteries (e.g. lithium batteries) or even non-rechargeable
batteries into the charger. There is great danger of fire or explosion!
• Only operate the product in moderate climate, never in tropical climate. For more information on accep-
table environmental conditions, see the chapter „Technical Data".
• Never operate the device immediately after it was taken from a cold room to a warm room. The resul-
ting condensation may lead to malfunctions or damage! The mains unit poses a danger of potentially
fatal electric shock!
• Let the product reach room temperature before taking it into operation again. This may take several
hours!
• Avoid operation in direct proximity of strong magnetic or electromagnetic fields, transmitter aerials or
HF generators. This can affect the control electronics.
• If you have reason to believe that the device can no longer be operated safely, disconnect it immediate-
ly and make sure it is not operated unintentionally.
Then disconnect the charger from the voltage supply and unplug the mains cable from the mains outlet.
Do not use the product anymore after this, but take it to a specialised workshop or dispose of it in an
environmentally compatible manner.
• It can be assumed that operation without danger is no longer possible if the device has any visible da-
mage, the device no longer works, after extended storage under unsuitable conditions or after difficult
transport conditions.
• If the product is not to be used for an extended period of time (e.g. storage), remove any rechargeable
batteries inserted in the charger, disconnect the charger from the operating voltage and pull the mains
cable of the mains unit from the mains socket.
Keep the entire product at a dry, clean site that is not accessible to children.
