Location tips
• Select a stable, level base.
• Make sure that the environment is
clean and free from dust.
• Avoid placing the unit close to sources of heat or in direct sunlight.
• Arrange the connector cables so that
they do not pose a trip hazard.
• Do not place any heavy objects on
the cables or the speakers.
Prerequisite for the microphone function: The jack Mic Out (5) must be con-
nected to the microphone input jack of
the PC/notebook (see step 4 on the previous page).
Note: If you connect headphones to the
jack Phones (4), the speakers will be automatically muted. Sound will only be
played back via the headphones.
The speakers should be situated to the
left and right of the monitor and if possible, form an equilateral triangle with
the listener – the so-called stereo triangle (distance from the listener = distance between the speakers). The speakers should project sound directly into the
room or be arranged slightly towards
the listener.
There should be approx. 10 cm of space
between the back of the speakers and
the wall.

Protecting the environment
Disposing of the device
Used units must not be disposed of with household
waste!
If the unit is no longer opera-
tional, every consumer is required by law to dispose of used devices
separately from household waste, e.g. at
a collection point run by the communal
authority borough. In this way it is ensured, that used devices are properly recycled and that negative consequences
on the environment are avoided. For this
reason, electrical equipment is labelled
with the displayed symbol.
