______________________________________________
To ensure that these high-quality, easy-to-use loudspeakers provide you with
lasting enjoyment, please observe the following instructions when setting them
up.
These loudspeakers are designed for the playback of audio signals.
Any other use is expressly prohibited.
When transporting the loudspeakers only pick them up using the aluminium fra-
mes on the sides.
If the loudspeakers are subjected to sudden changes in temperature, for exam-
ple if they are brought in from the cold to a warm room, connect them to the
mains supply and let them stand for at least two hours.
The loudspeakers are designed for use in dry rooms. If you do use them in the
open, please ensure that they are protected from moisture, such as rain or lawn
sprinklers.
Do not place the loudspeakers close to heating units or in direct sunlight, as this
will impair cooling.
Do not open the loudspeaker casing under any circumstances. The manufacturer
accepts no liability for damage resulting from improper handling.
Thunderstorms present a danger to all electrical devices. Even if the loud-
speakers are switched off, they can be damaged by a lightning strike to the
mains. Always remove the mains plug in the event of an electrical storm.

The wireless transmission system
Your loudspeakers are equipped with an HF system which enables them to trans-
mit and receive audio and data signals without the need for cables.
The HF transmission strength is limited by national and international regulations
to prevent radio interference from neighbouring devices.
The HF transmission power is < 10 mW. This guarantees an unhindered recepti-
on range of approximately 30 m. This range is restricted inside buildings,
depending on the construction materials used.
Avoid placing the loudspeakers near metal objects such as radiators or electri-
cal devices such as cordless telephones which use radio signals.
Since the audio and data signals are not transmitted on an exclusive range we
cannot guarantee that this will not cause interference. To avoid interference you
can change the communication channel for the audio signal.
In some circumstances, people, walls and other surfaces can reflect radio sig-
nals. Reflected signals can mix with direct (non-reflected) signals thus causing a
type of interference known as multi-path reception. This can lead to noise or a
temporary loss of sound. If such interference does occur, simply position the
loudspeakers differently.
