3.0 SAFETY NOTES
n Use only originally supplied accessories
n Before you make any connections: disconnect your equipment from the 230 V
main power to avoid electrical shocks during installation
n Short Circuit in the coaxial cable MAY permanently damage your Digital Receiver
n Never install the Antenna outside your house or in humid rooms such as bathrooms
n Never use AC Adaptors with wrong specifications, this MAY permanently damage
your antenna or Digital Receiver. Always check voltages and polarisation of the
adaptor before connecting it
4.0 CONNECTING THE ANTENNA
1. Check if the broadcast in your country is Horizontal or Vertical polarized
2. Click the Antenna in the plastic holder as shown in the pictures
3. Disconnect your Digital Receiver from the 230 V main power
4. Connect the supplied coaxial cable to the antenna: carefully press the inner
lead of the cable into the Female-F connector at the back of the antenna. Turn
the covering nut clockwise with your HANDS until it is fixed
5. Connect the other side of the coaxial cable to your Digital Terrestrial Receiver.
Normally the input connector on your receiver is marked as “ANT” (in) or as
“RF”(in). Refer to the User Manual of your Digital Terrestrial Receiver

5.0 INSTALLATION OF THE ANTENNA
A. To power the antenna with Digital Terrestrial Receiver
1. Turn on your TV set and turn on your Digital Terrestrial Receiver.
2. Press the [MENU] button on the remote control of your Digital Terrestrial
Receiver. Check in the Set-Up or Installation Menu of your Receiver if the
antenna power is set to “ON”. (Normally this is indicated in the menu as ANT
power, Ext Antenna power or Active antenna power).
Refer to the User Manual of your Digital Terrestrial Receiver.

PART 1 • English
3. Select in the Menu of your receiver the field that shows you the signal level
indicators. (Normally you can find the signal meter in the Channel Scan field
of the menu).
4. Now optimise the signal strength by finding the best position for the antenna.
Keep the antenna in your hand and try to reach the highest possible position.
Now slowly turn the antenna around it’s axis (in the horizontal field), at the
same time monitor the signal bars in the menu, once the signal indicator
shows the maximum signal, fix the antenna on that position.
5. It is important to place the antenna in such way that an acceptable signal
level is assured. You can optimise the signal strength by moving the antenna
to different locations in your room, for example place it near a window, or
place it on a high placed book-shelf. The best position can be found by trying
different locations.
Note - It is recommended NOT to place the antenna near to:
n Devices that are strong source of radiation or interference such as DECT and
GSM telephones, Transmitters, Microwaves, etc.
n Devices with high power consumption such as Electrical Heater, Air conditioner,
Hairdryers, etc.
B. To power the antenna with extra power adaptor
1. Use this installation if your Digital Terrestrial Receiver does not support
active antenna.
2. Connect supplied power adaptor to “DC IN”
connector on the back of antenna.
3. Proceed with positioning of antenna as
described above in section A (points 3, 4, 5).
Note: The antenna will not function properly if the build-in amplifier is not powered.
Therefore it is required to supply the antenna with power via the coaxial cable or
via a external adapter.
Extension of the coaxial cable:
In some cases you may need to extend the standard supplied coaxial cable, we advise you
to only do this if you can not get a optimal signal strength within the reach of the standard
cable. If you are to extend the coaxial cable, then please note following comments:
n Use a good quality coaxial cable, 75 Ohm type only with proper shielding
n Use well shielded connectors, your dealer can advise you on this
n Make sure that both inner cable and shielding are properly connected to the connectors to
assure active antenna power supply and to avoid short circuit in the cable
If you extend the cable, please keep the cable as short as strictly needed. Extending the
cable or using bad quality cable will reduce the performance of your antenna.
