Now that you have acquired your satellite follow these steps to further
improve your signal. While the display is showing found move the dish
very slowly off the target satellite in either a left or right direction
(Azimuth adjustment) until the signal level just starts to drop away and
make a mental note of the position of your dish, now move the dish
back in the opposite direction watch where the signal level peaks and
continue until the level just starts to drop off again. Now move you dish
back to the centre of these two points (the azimuth is now optimised).
Tighten the clamp bolts to lock the azimuth position.
We can apply the same procedure to the up and down motion (Elevation
adjustment), again we are looking to see where the signal just starts to
fall away and move while moving up in elevation make a mental note of
that position and then adjust the elevation down until the signal level just
starts to drop off again. Then return your elevation position to the centre
of these two points (the elevation is now optimised). Tighten the elevation
bolts.
The final step for making fine adjustments to optimise your signal is the polarisation of the LNB (adjusting the
skew). Depending of the style of dish you own this can take two different forms. One adjusting the skew of the
whole dish (via a mounting plate on the rear of the dish) or two rotating the LNB clockwise or counter-clockwise
in the LNB clamp. For the United States it is common to have the former (whole dish is rotated) where as in
Europe and the rest of the world it is typically the latter (rotating the LNB in its clamp).

We can apply a similar procedure for the skew adjustment, again we are
looking to see where the signal just starts to fall away and move while
rotating the LNB (or dish assembly) make a mental note of that position and
then adjust the skew in the opposite direction until the signal level just starts
to drop off again. Then return your skew position to the centre of these two
points (the polarisation is now optimised). Tighten the LNB clamp.
Following the procedures above will greatly improve the performance of your dish, and over time your familiarity
with installing your own dish will enable you to complete this procedure quickly.
IMPROVING YOUR SIGNAL
The DSM-4S is a satellite finding device it is not designed to be permanently left
in line between your LNB and set top box. Once the installation is complete
remove your DSM-S4 and re-connect the LNB to the receiver.
