• Never touch the mains plug when your hands are wet.
• The device is manufactured according to protection class 1. Only use a standard mains socket (220 - 240V
/50-60 Hz connected to the public supply network with an earthed contact as the voltage source.
• Extra care should be taken when using the device for the fi rst time. Therefore, please follow the operating
instructions carefully.
• Further, always observe the safety and operating instructions of any other devices that are connected to the
active monitor loudspeaker.
• Make sure the mains cable is not pinched, bent, damaged by sharp edges or otherwise subjected to me-
chanical strain. Avoid excess thermal stress on the mains cable due to excess heat or cold. Do not modify
the mains cable. This may damage the mains cable. A damaged power cable can result in a life-threatening
electric shock.
• If the power cable is damaged, do not touch it. First, switch off the appropriate mains socket (e.g. via the
respective circuit-breaker) and then carefully pull the mains plug from the socket. Separate the mains cable
from the device. Never use the product if the power cable is damaged.

• This product is not a toy, it is not suitable for children. Children are not aware of the potential dangers
involved when using electrical devices.
• Never pour liquids over electrical devices and never place objects fi lled with liquid on top of them (e. g.
vases). You run the risk of causing a fi re or a fatal electric shock. If this is the case, de-energise the ap-
propriate socket (e.g. switch off circuit breaker) before removing the plug-in mains unit from the socket.
Disconnect all cables from the device. Do not use the product afterwards. Take it to a specialized workshop.
• Do not place naked fl ames such as burning candles on top of the device.
• Do not keep any magnetic storage media such as disks, video cassettes or similar close to the active moni-
tor loudspeaker as the magnetic fi eld of the loudspeaker may corrupt the information stored on these media.
