• For safety reasons, any unauthorised conversion and/or modification of the product
is not permitted.
• The power supply unit has been constructed according to Protection Class II and
may only be operated on a public power supply outlet.
• Never touch the power supply unit with wet or damp hands. There is risk of a life-
threatening electric shock!
• Never replace a damaged connecting cable to the power pack. If the connecting
cable is damaged, the power adapter is unusable and must be disposed of. Do not
repair it.
• To disconnect it completely from the mains, the mains plug has to be removed from
the mains socket.
• The manufacturer’s safety instructions for devices to be connected must also be ob-
served. You should, therefore, also carefully read other relevant operating instruc-
tions.
• Do not operate the product if it is damaged.
• This product is not a toy, and should be kept out of the reach of children. Children
cannot see the danger arising from the incorrect use of electrical devices.
• Never pour fluids above electrical devices. Do not place any containers with liquids,
such as buckets, vases or plants, in the immediate proximity of the product. Liquids
could get inside the housing and thus impair electrical safety. There is danger of fire
or a life-threatening electric shock! If liquid has entered the device, switch off the
respective mains socket (e.g. switch off circuit breaker) and pull the power adapter
from the socket. Afterwards, the product must no longer be used. Please take it to a
specialist workshop.
• The device may not be exposed to extreme temperatures, strong vibrations, high
humidity (e.g. droplets or splashes of water) or strong mechanical stress.
• Do not place open flames, such as burning candles, on or near tthe device.
• Use the device only in temperate climate regions and not in tropical ones.
• Do not leave packaging materials unattended. It may become a dangerous plaything
for children.
• If you have doubts about how the product should be operated, or about safety or the
connection, consult an expert.
• If you have any questions that are not answered in these operating instructions,
please contact our technical support centre or consult a professional.
Set-up
Do not drill any additional holes or screw any additional screws into the
housing when mounting the DVB-T antenna, as doing so could damage it.
When setting up the antenna, make sure that it has a secure footing and is
on a stable surface, as people could be injured if the device is dropped..
Avoid placing the DVB-T antenna near devices that can transmit interfer-
ence (e.g., microwave ovens, cordless phones, powerful engines, etc.).
You should also not install the device close to large metal surfaces, because
these may significantly weaken the received signal.
Place the antenna at the highest possible location, since experience shows
that this is where the reception is best. Installing it close to a window may
also improve reception.
• Put the antenna on the stand provided. The antenna can be inserted into the stand
either vertically or horizontally, depending on the reception. There are two lugs at
the housing, which click into the stand.
• Place the antenna on a flat surface.
Connection and commissioning
The antenna cable of the antenna may be connected only to the antenna
inputs of the corresponding receivers.
Use only the power adapter enclosed in the package or the 5 V phantom
power of your receiver (if available) to supply the power.
Connect the power adapter only to a normal mains socket connected to the
public supply.
Be careful when handling the mains cables and mains connectors. Mains
voltage can cause serious electric shocks, which can be fatal.
Make sure that the current designation on the power adapter agrees with
the mains voltage of your power supply. Never try to operate the power
pack on any other voltage.
When making the connections, make sure that the connecting cables can-
not be pinched or damaged by sharp edges.
The mains socket to which the power adapter is connected must be nearby
and easily accessible, so the device can be quickly isolated from the mains
power supply in the event of a fault.
Operation together with the external amplifier is recommended for most reception
conditions as it can amplify the signal quality in most cases.
Thus, you should test operation with the external amplifier, initially using the connec-
tion without an amplifier only when the signal reception deteriorates due to amplifica-
tion. This can lead to overdrive of the antenna input in areas with very good reception
conditions.

as a power supply. The power adapter is only permitted for connection to an alternat-
ing current of 230-240 V/50Hz.
The product may only be used in enclosed indoor locations. Outdoor use is not al-
lowed. Do not expose to moisture, under any circumstances.
Any use other than that described above could lead to damage to this product and
involves the risk of short circuits, fire, electric shock, etc.
Read the operating instructions carefully and keep them for later reference.
No part of the product may be modified or converted.
