• Gently raise the hinged section of the antenna to the vertical position as shown in the image on the
packaging.
• Place the antenna in a position with good reception, for example near a window or in the direction
of the television station, away from metal objects, electrical appliances and reinforced concrete
walls which can attenuate the signal and limit its operation.
• Connect the Meliconi antenna cable [A] to the antenna input socket on the TV (or digital terrestrial
decoder).
• Connect the end [C] of the power cable to the antenna socket [B]; insert the other end of the
power cable [D] into a free USB socket on the TV (or decoder). In this way the TV (or decoder) will
automatically supply power to the antenna only when it is switched on.
• Turn on the device (TV / DECODER) and select the desired channel. Check that the BLUE LED
on the front of the antenna turns on. When the TV (or decoder) is turned off, the antenna (and LED)
should turn off.
If your TV / decoder does not have a free USB socket, you can power the antenna in the
following ways:
B1 POWER SUPPLY FROM DECODER
• If the antenna is connected to a suitably equipped digital terrestrial decoder, the decoder can
power the antenna via the antenna cable [A] (refer to the decoder's user manual to enable the
5 Volt/Antenna connection).
Check that the blue LED on the front of the antenna turns on when decoder is on. In this
configuration, when the decoder is turned off, the antenna (and LED) will automatically turn off.
B2 EXTERNAL POWER SUPPLY
• Use a standard 5 VDC/1 A USB power supply (not included) that complies with current safety
regulations.
Meliconi S.p.A. denies any and all liability resulting from use of external power supplies.
C
If the image quality is unsatisfactory or no signal is received, proceed as follows:
• Check that the antenna is on: blue LED on.
• Gradually turn the antenna until you get the best reception.
• Adjust the gain with the amplification adjustment wheel [MAX-MIN / OFF]; the maximum gain
setting does not always give the best image quality. Try reducing it a little.
• Look at the antennas on the roofs of neighbouring buildings and turn your antenna in the same
direction as them.
