Improving Reception - MELICONI AT55 Black Instrucciones De Uso

B
• 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 cable [A] of the Meliconi aerial to the antenna input socket located on the television
set (or on the digital terrestrial decoder)
• rotate the knob [D] in an anticlockwise direction and adjust for maximum amplification.
• Use the power cable [B] and connect [F] to the aerial [C]; insert the other end of the power cable
[G] in a free USB socket on the television set (or decoder). In this way, the TV (or decoder) will
automatically supply power to the aerial only when it is turned on.
• Turn on the device (TV / DECODER) and select the desired channel. Check that the aerial's LED
(H) is lit.
If your TV/Decoder does not have a free USB socket, it is possible to power the aerial in the following
ways.
External power source
• Use the power unit [E] supplied. Connect the aerial's power cable [G] to the USB socket of the
power unit [E]. Insert the power unit [E] in an electrical socket 230V~ / 50 Hz. Check that the front
LED [H] is lit.
Note: The AT55 Black 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 suitable digital terrestrial decoder, it is possible to supply power to
the aerial by using only the aerial cable [A] (refer to the User's Manual of this device to enable
the 5 Volt/Antenna output). Check the LED (H) lights up when the Decoder is turned on. In this
case, when turning off the Decoder, the aerial and the LED are automatically turned off.
C
If the quality of the image is unsatisfactory or no signal is received, try the following:
• Check that the aerial is turned on: LED [H] lit
• Point the aerial in different directions until optimal reception has been obtained.
• Adjust the gain using the amplification control (knob [D]); the maximum gain value does not
always result in better image quality. 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).
