Putting the conference system into operation
Setting up and positioning the antenna module
The antenna module can be:
mounted to a wall or ceiling by means of a ball joint (optional accessory),
mounted to a stand or
placed on a flat surface (e.g. table).
The transmission range of the antenna module and the wireless conference units
is approx. 30 m. The transmission range can vary depending on location and envi-
ronmental conditions such as wall thickness, wall composition etc.
Do not obstruct the antennas of the antenna module and the wireless confer-
ence units with any object.
CAUTION
Danger of injury and material damage!
If
im
properly installed or insufficiently fixed, the antenna module
can fall from the wall, ceiling or stand or tip over and can cause injury
or material damage.
Protect the antenna module against
tipping or dropping by
means of a safety wire which is attached to a separate hook.
Always have the antenna module mounted by a qualified special-
ist according to local,
national and international regulations and
standards.
If necessary, use several antenna modules in order to provide optimal
antenna coverage.
CAUTION
Danger of intermodulation!
If you set up the antenna module and the wireless conference units too close to one
another, intermodulation can occur.
Observe a minimum distance:
of 1 m between the wireless conference units and the antenna module and
of 0.5 m between the wireless conference units.
We recommend using several antenna modules in rooms with
obstacles.
In some countries/regions (e.g. Canada), the use of wireless compo-
nents operating in the 5.15 to 5.25 GHz frequency band (channel 5
to 8) is restricted to indoor use.
