• Maintenance, modifications and repairs are to be performed exclusively by an expert or at a qualified
shop.
• If you have questions which remain unanswered by these operating instructions, contact our technical
support service or other technical personnel.
b) Electrical devices
• Never pour any liquids over electrical devices or put objects filled with liquid right next to the device. If
liquid or an object enters the interior of the device nevertheless, first power down the respective socket
(e.g. switch off circuit breaker) and then pull the mains plug from the mains socket. Do not operate the
product anymore afterwards, but take it to a specialist workshop.
• Never use the product immediately after it has been brought from a cold room into a warm one. The
condensation generated could destroy the product. The power adapter also involves danger to life by
electric shock! Allow the device to reach room temperature before connecting and using it. This may
take several hours.
c) Power adapter
• The adapter corresponds to protection class II. Only a proper mains socket (100 - 240 V/AC, 50/60 Hz)
of the public electricity supply may be used as voltage source.
• If the power adapter is visibly damaged, do not touch it. Risk of fatal injury due to electric shock! First turn
off the power supply to the power outlet that the power adapter is connected to (flip off the fuse and then
turn off the residual current operated circuit breaker to disconnect the power outlet at all phases). Now
unplug the device from the power outlet. Dispose of the power adapter in an environmentally friendly
fashion, discontinue use of it immediately. Replace it with an identical power adapter.
• The mains outlet must be located near to the device and be easily accessible.
• Only use the supplied mains adapter as a power supply.
• Only connect the power adapter to a normal mains socket connected to the public supply. Before
plugging in the power adapter, check whether the voltage stated on the power adapter complies with the
voltage of your electricity supplier.
• Disconnect the mains adapter from the wall socket after use.
• Never connect or disconnect power adapters if your hands are wet.
• Never unplug the power adapter from the mains socket by pulling on the cable; always use the grips
on the plug.
• For safety reasons, disconnect the power adapter from the mains socket during storms.
