A08 - 25.09.2015
VTQ WMS HD - V/G-Mount TX
Please always pay attention to the following warning instructions:
Just install the system in accordance with this reference guide.
Please exclusively use accessories authorized by the manufacturer.
Keep the system away from:
- places with high humidity
- places exposed to direct sunlight
- places with high temperatures
- places near open fire
Do not place the system near easily flammable substances like alcohol or thinners. In the event
that the internal electrical parts come into contact with easily flammable substances, there is a
danger of a fire outbreak or an electric shock.
Please prevent the system from rain or moisture in order to avoid the risk of a an electric shock.
In case liquids or similar substances end up inside the unit, please immediately disconnect the
voltage supply and contact the manufacturer.
Do not open, disassemble or modify the system. Incorrect handling may result in fire or electric
shock.
Do not connect the hardware with power supply units or voltage sources with a different voltage
than required or specified. The wrong voltage may result in fire or electric shock.
In case of thunder storms or when the system is not being used for a longer period of time,
please - as a precaution - disconnect the plug from socket.
Allow only the authorized manufacturer to carry out maintenance. The system has to be serviced,
if it has been damaged in any way (for example when liquids or items got into the system, when
the system was exposed to rain or moisture, when it does not work duly or was dropped and hit
the ground).

2.2. Assessment of the production environment
The exact observation and assessment of the production environment is the basic requirement to
ensure an ideal transmission.
» Which buildings and structures are located
in the surrounding area?
Radio signals are electromagnetic waves.
When these waves encounter an obstacle,
they will be reflected, attenuated or even
completely absorbed due to their physical
properties.
In general: The lower the frequency, the
better the penetration. The higher the
frequency, the worse the penetration.
» Which negative consequences result from
this?
Especially objects or structures made of
steel or metal can stop radio waves. This
also includes fences made of wire, steel
reinforcement in the masonry or metal
coated window panes.
Leaves from trees or bushes or rain or snow
as well lead to the attenuation or absorption
of the signal.
» Which positive effects does the
surrounding have for the transmission?
Smooth surfaces of buildings made of
masonry or reinforced concrete can be
used as reflection surfaces, in favor of the
transmission quality and range.

2.3. Alignment and positioning of the antennas
» Selection of appropriate antennas
Pay attention to the correct frequency
range! Short antennas are optimal for
mobile applications, but normally are less
sensitive. Long antennas are more sensitive,
but are not appropriate for mobile
applications, as the antenna socket is
exposed to a greater leverage when under
intense pressure and can be damaged as a
result of this.
» Pay attention - if possible - to the identical
altitude of transmission and reception
antennas.
4dB Antenna
6dB Antenna
» Take care that the antennas are (as much
as possible) unobstructed !
Avoid every limitation of the transmission
and reception area by buildings or walls
directly at or in immediate surrounding of
the antenna.
Please make sure that, especially in a
mobile production, the antennas are able to
transmit and receive in all directions freely.

2. Before operation
» Pay attention to the polarization of the
antennas.
Omnidirectional antennas normally are used
in vertical operation. Transmission and
reception antennas always have to be
aligned identically!
Exception:
fast-moving camera work, for example in
operations with steadycam etc.
Possible antenna configuration at the
receiver:
antenna 1 vertical (90°),
antenna 2 horizontal (0°)
or
antenna 1 turned to 45°
antenna 2 turned to 135°
» Installation of antennas
(by grip, universal clamps etc.)
The grip is to be attached exclusively at the
lowest end of the antenna (maximum 4cm
from the lowest end), else the properties of
the antenna will be negatively affected.
