2 - Installation of a fixed dish on a satellite
Read the installation advices, and particulary the paragraph B.
For the alignment, you just have to run one cable.
A - Connections
The receiver must be disconnected from the mains, connect directly the LNB to the LNB input
of the receiver. Connect the television to the receiver scart socket output. Switch on the televi-
sion and connect the receiver to the mains. Put the switch ON and press the power key (
)
of the remote control, the green LED lights on. If the television does not display a black screen
with a message «BAD OR NO SIGNAL», check the scart leads connections and/or force the
A/V or EXT mode of your television (see your TV user manual).
B - Alignment / Satellite dish orientation
Find in Table 1 (page 9) channel number of the reference channel of the satellite that you wish
to receive (example: 400 = BBC ONE for Astra 28°). Type on the remote control the channel
number.
Press on the remote control INFO key to show the
reception level. This indicator shows normally 0%;
the alignment will consist in directing the satellite
dish toward the satellite, leading to a maximum
level and quality.
Beware, it may be useful to search for the south
with a compass. However, never use a compass
to find the supposed location of a satellite. For ins-
tance, you may guess that Astra 28° is located 28°
left from south. It’s false! Just sweep the dish as
explained, this method works better.
Put the satellite dish in a vertical position (the graduations on the back show 20-25°) and
roughly direct it towards the south. Make a slow sweeping (about 20 seconds) of a quarter of
a spin on the left then a quarter of a spin on the right while checking on the television. The
indicator should not show anything at this stage.
Incline the satellite dish of 2 degrees (a little less than 1 inch at the top of the dish) towards
the top and then start again the sweeping.
Proceed by 2 degrees steps until the indicator goes up and that the channel appears. Tighten
all the screws definitively, except those which fixing the LNB in its holder. If the indicator
increases, but no images appear on the screen, it means you are on another satellite, it is
necessary to continue sweeping.
C - Adjustment of the polarisation
Rotate the LNB clockwise in its holder for a few degrees to further increase the quality of
signal. If the signal decreases, rotate it in the opposite direction.
