Dear customer, the following safety information is intended not only for the protection
of your health but also for the protection of the device. Please read the following items
carefully:
• For safety and licensing reasons (CE), unauthorised conversion and/or modification
of the device is not permitted.
• The product is not a toy and must be kept out of the reach of children! The product
may only be set up, used or stored in places that are not accessible to children. The
same applies for rechargeable batteries.
• Children could change the settings or short-circuit the rechargeable battery/battery
pack, which can lead to an explosion. Danger to life!
• The product is intended for dry indoor use only. It must not become damp or wet.
However, do not use the battery charger inside a vehicle.
• Select a stable, flat surface which is large enough and smooth. Never place the
battery charger and the battery on a flammable surface (e.g. carpet). Always use a
suitable, non-flammable, heatproof surface, e.g. a stone tile).
• Maintain enough distance from flammable objects. Leave enough distance between
the charger and the rechargeable battery - never place the rechargeable battery on
the charger.
• Ensure that there is sufficient ventilation during operation. Never cover the battery
charger and/or the connected rechargeable battery.
• Avoid operation in direct proximity of strong magnetic or electromagnetic fields,
transmitter aerials or HF generators. This can affect the control electronics.
• Never operate the device immediately after it was taken from a cold room to a warm
room. The resulting condensation may lead to malfunctions or damage! Allow the
charger (and the rechargeable battery/batteries) to reach room temperature before
connecting the charger to the power supply and using it. This may take several
hours!
• Do not expose the device to direct sunlight, high temperatures (>35 °C) or extreme
cold (<0 °C). Keep it away from dust and dirt.
• Do not place any containers filled with liquid, vases or plants, on or next to the
charger. If they call over, this may destroy the charger and there is a high risk of
fire.
• 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.
• Only operate the product in moderate climate, never in tropical climate. For more
information on acceptable environmental conditions, see the chapter „Technical
Data“.
• Services, adjustments and repairs must only be carried out by a specialist/specialist
workshop. The device contains no parts that require servicing or adjusting by you.
• Handle the product with care - hits, knocks or falls from even a low height may
damage the product.
• In schools, training centres, hobby and self-help workshops, the handling of
chargers and batteries must be responsibly supervised by trained personnel.
• If you have reason to believe that the device can no longer be operated safely,
disconnect it immediately and make sure it is not unintentionally operated.
It can be assumed that operation without danger is no longer possible if the device
has any visible damage, the device no longer works, after extended storage under
unsuitable conditions or after difficult transport conditions.
• Do not leave the packaging material lying around carelessly since such materials
can become dangerous toys in the hands of children.
• Rechargeable batteries must not be short-circuited, taken apart or thrown into fire.
There is a risk of fire and explosion!
• Leaking or damaged rechargeable batteries may cause caustic burns if they come
into contact with skin. Therefore you should use suitable protective gloves for this.
• Please observe correct polarity (plus/+ and minus/-) when connecting the
rechargeable battery to your model or charger. Connecting the battery incorrectly
will not only damage the model but also the rechargeable battery. There is a risk of
fire and explosion!
• Also observe the safety information of the rechargeable battery manufacturer.
If you are not sure about the correct connection or operation, or if there are any questions that
are not covered by the operating instructions, do not hesitate to contact our technical support or
another specialist.
