MELICONI AT52 R1 Mode D'emploi page 10

B
• Insert the stand as indicated in Figure 1
• Position the aerial in a favourable location for signal reception, for example, close to a window and
or in the direction of the television station, far from metal objects, electrical equipment and
reinforced concrete walls that could attenuate the signal, limiting its operation.
• Connect the Meliconi aerial cable [A] to the antenna input socket on the television set (or on the
digital terrestrial decoder).
• Rotate the knob [D] in an anticlockwise direction to maximum amplification.
• Use the power cable [B] and connect [F] to the socket [C]; insert the other end of the power cable
[G] to a free USB socket on the television set (or decoder). In this way, the TV (or decoder) will
automatically supply power to the antenna only when it is turned on.
• Turn on the device (TV / DECODER) and select the desired channel. Check that the LED (H) of
the antenna is lit. When the TV (or decoder) is turned off, the aerial and the LED will usually turn off.
If your TV/Decoder does not have a free USB socket, it is possible to supply power to the aerial in
the following ways.
External Power Source
• Use the power unit [E] provided. Connect the aerial's power cable [G] to the USB socket of the
power unit [E]. Insert the power unit [E] in an electric socket 230V~ / 50 Hz. Check that the front
LED [H] is lit.
Note: The AT52 R1 aerial does not have a switch. In this configuration, the power unit [E] must be
disconnected from the socket in order to turn off the aerial.
Power supply from decoder
• If the aerial is connected to a compatible digital terrestrial Decoder, it is possible to draw power
for the aerial from the decoder, using only the aerial cable [A] (refer to the decoder's User Manual
to enable the 5 Volt/Antenna output). Check that the LED (H) is lit when the Decoder is turned out.
In this case, when turning off the Decoder, the aerial (and the LED) automatically turn off.
C
If the quality of the image is unsatisfactory or no signal is received, do the following:
• Check that the aerial is turned on: LED [H] lit
• Point the antenna in different directions until optimal reception has been obtained.
• Adjust the gain by adjusting the amplification (knob [D]); the maximum gain value does not
always correspond to better quality of the image. Try reducing it a little.
• Look at the aerials on the roofs of nearby buildings and try to point the aerial in the same
direction.
• If possible, it is recommended to carry out the tuning of the channels on the device (TV /
DECODER) by connecting it temporarily to a different, valid signal source (for example, a
condominium aerial).
