Safety information:

  • Always check that the mains voltage of the socket matches the voltage indicated on the device before plugging it in.
  • Make sure that electronic devices are well ventilated and do not overheat. Do not place them on soft surfaces such as beds or pillows that could block the ventilation slots.
  • Keep electronic devices away from water and damp environments to avoid short circuits and electric shocks. Do not use them near sinks, bathtubs or other water sources.
  • Regularly check the cords and sockets of your devices for damage or wear. Do not use devices with damaged cords or loose sockets.
  • Always switch off and unplug electronic devices before cleaning them. Do not use liquid cleaning agents or sprays directly on the device. Use a slightly damp cloth instead.
