Your DSM-4S is ready to use straight out of the box. How to connect your meter is illustrated below.
Note: Always make all of your connections prior to switching your DSM-4S on.
For the easiest method of connection disconnect the cable from the LNB on your dish and connect this to
the Set Top Box (receiver symbol) connector on your DSM-4S. Then use the short F cable supplied with
your DSM-4S to connect your LNB (dish symbol) connector to the LNB as shown above.
After your connections have been completed ensure that your set top box is switched on with any channel
selected. Tip: Ensure that the F connectors are hand tight and not loose (good connections are essential).
Tip: Other types of LNB such as Quad or Dual should be connected in the fashion illustrated below.

Now that you have connected your DSM-S4 you are ready to find some satellites. Your DSM-S4 will be pre-loaded
with a selection of satellites. These selections can be changed by downloading different region packs from the
Eurosat web site.
In the following examples we will be looking at the European pack of satellites which comprises of the following...
Astra 2A
Astra 2D
Astra 1
28.2' East
28.2' East
19.2' East
13.0' East
European Beam
UK Spot Beam
European Beam
European Beam
Note: Beam refers to where this satellite is available Astra 2D has a narrow beam focused over the UK for local
network services specific to the United Kingdom.
Switch on your DSM-S4 by holding the function button. After the start up has completed you will be presented
with the satellite finding mode. Press the function button until your desired satellite from the pre-loaded pack is
displayed. To switch the DSM-S4 off press and hold the function button.
Tip: For locations above the equator (Europe for example) satellites will be
located on the Southern horizon, with the use of a compass we can quickly
eliminate half of the visible sky, for the European satellites we can further
reduce our search area by focusing on the South East region of the visible
sky as the European satellite pack pre-loaded into your DSM-S4 is looking
for satellites in this region.
Astra 2D 28.2E
Satellite finding is best done with the following technique. Ensure that your satellite dish is mounted on its fixings
so that the bolts are biting just enough to allow you to move the dish and it will hold its position in both Elevation
and Azimuth (side to side and up and down motion). Also the LNB clamp should be tight enough to hold the LNB
in place when you are adjusting the skew (clockwise and counter-clockwise rotation of the LNB). Some LNB’s
have a 5 position adjuster for this purpose and come with the LNB skew preset (typically on small dishes) as
supplied by the satellite service operator.
Point your dish slightly downwards so that the face is about 5 to 10 degrees off vertical and slowly move your
dish from east to west across the horizon in a slow smooth motion keeping an eye on your meter display. On
reaching the end of each sweep tilt the dish back a little (raising the elevation) and sweep back again in the
same slow smooth manner. You will notice that the signal level display will rise and fall as you pass different
satellites. When you are getting close to your selected satellite the unique satellite direction finding system will
display arrows telling you which way to move your dish (from the perspective of standing behind your dish).

Once you have found your satellite the satellite dish icon will be come solid and a melody will play, the word
“Found” will also appear in the lower left corner of the LCD display. On locating your satellite you can further
peak the signal by following the steps on the next page, to improve the performance of your satellite system.
Page 5
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
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.
