of the included power cord.
16. Do not turn on the device immediately if it was exposed to strong temperature fluctuations (for example after
transportation). Moisture and condensation may damage the device. Leave the device switched off until it has
reached room temperature.
17. Do not open the device and do not make any changes to the device.
18. Before connecting to mains power, make certain that the mains voltage and the mains frequency are the
