Product descripon
The SF 2500 Pro microprocessor-controlled satellite finder with new and improved electronics
enables you to quickly and easily align your satellite system in a precise and reliable way. Accurate
results are provided via both the backlit display and an acoustic signal.
This device is very sensitive and can pick up even the weakest signals. Strong input signals
(through powerful satellites or large satellite antennas) can be easily attenuated using the
“Attenuation +/-” buttons and the lateral adjustment wheel. The device can be configured with
all types of satellite systems and produces highly accurate readings.
The satellite finder is powered through the LNB operating voltage by the receiver/TV or
multiswitch and does not require an additional power supply.
The Satfinder must be used near the satellite dish! In the living room or attic the function may
be restricted (cable attenuation).
i

Keep the signal level display region
at approx 50% by reducing or increasing the
aenuaon.
An increase or decrease in the level can thus
be idened.
If aenuaon is acvated,
“ATT” appears on the display.
The adjustment wheel is very sensive.
 In addion, use the “Aenuaon +/-”
buons.
3.3 Opmally align the antenna by
gentle turning and lng
The antenna is opmally aligned
when the signal strength cannot
be increased anymore.
It is oen possible to somewhat increase the
quality by turning the LNB in its retaining
clamp in small increments, known as skew
opmisaon (not necessary for Astra 19.2°).
1 Prepare the satellite dish
2 Start operang the Sainder
3 Adjust the satellite dish more precisely
4 Check the TV picture and remove the Sainder

4.1 Check the picture of a number of channels on your TV (if necessary, start a channel search)
It is most likely that the satellite dish is aligned towards a different satellite, if no channels or the
wrong channels are received. Some satellites are in close proximity to each other.
Check the Azimuth angle and adjust again.

4.2 Switch off the receiver/power supply
Firstly, separate the receiver from the mains to avoid short circuiting.

4.3 Fasten the satellite dish crosswise and remove the satellite finder from the signal path.
Finally, connect the supply cable to the LNB - job completed!


2.1 Connect the Sainder with the LNB
Use the coaxial cable that was included with
the product – connect the “LNB” connector
to the LNB output.
2.2 Connect the receiver/power supply
(receiver is o)
Connect the (receiver) supply cable to the
connector that is labelled “Receiver”
2.3 Switch on the receiver/power supply
The receiver now supplies the power
to the satellite nder – the satellite nder
starts.
The satellite nder potenally displays a reading,
oen 99% or 0%
 Turn the adjustment wheel.
2.4 Aenuate the LNB background noise
Depending on the LNB type and background
interference radiaon, the satellite nder may
already display a reading even though a satellite
is not being located.
Before beginning the alignment, you must
aenuate the interference radiaon/back-
ground noise.
To do this, turn the lateral adjustment wheel or
press “Aenuaon” buons (ATT-), unl you
nd the threshold value and then adjust the
level to approx. 10%.
Now the satellite nder is ready to display
the satellite signals correctly.

3.2 Press the “Aenuaon +” or “Aenuaon -” buon, and carefully turn the adjustment
wheel (right) to keep the signal level bar in the middle (approx. 50%).
->Thus, there remains enough “leeway in the display” when adjusng to idenfy whether the
recepon is geng beer or worse.
If the display reaches approx. 99%, aenuate slightly again (buon/wheel) and adjust more
precisely.
Step 2: Roughly posioning the
satellite dish
You now need to align the antenna towards the
direcon in the sky
where the satellite is
expected.
Elevaon angle: Using the antenna
scale (back part)
Azimuth angle: align by compass
(E.g. smartphone/Sainder)
The dishes on neighbouring roofs
should serve as a guide.

Angle calculator
Rules of thumb:
1. Satellites that can be received in Europe are found in the South. The southern point corresponds
to 180° (E.g. use mobile compass).
Turn in a easterly direcon (to the le) or a westerly direcon (to the right) from this point. Astra 19.2° E
is located a few degrees to the east, so you therefore need to turn to the le (see Graphic 1).
2. It is also necessary to ensure that the antenna is adjusted to align with the correct elevaon angle.
Please ensure that no obstacles mask the view of the satellite. A clear view is absolutely essenal
(see Graphic 2).

Step 1: Determine the angle of the
satellites
It is necessary to know the approximate
posion on the horizon in order to quickly
align the antenna to the correct satellites.
For this purpose, either use
the easy online calculator at
www.durline.de/tools/satcalc.html
or scan the following QR code.

Reference direcons for the most com-
mon private and public broadcasters,

3.1 Turn the satellite dish CAREFULLY right and le –
observe signal strength bar or buzzer volume
If the antenna is roughly aligned, the signal strength bar in the display goes up.
The aim is to nd the point with the max. signal level, but not to reach a certain numerical value (such as 99%).
