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.

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.

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°).

1.1 Determine the angle for the
satellites
It is necessary to know the approximate
posion on the horizon in order to be able
to quickly align the
antenna on the correct
satellites. For this
purpose, use the easy
online calculator at
www.durline.de/tools/

or scan the following QR code.
Or,
You can nd reference values for most
private and public channels as well as Sky
in the table below.

1.2 Roughly align your satellite dish
Now align the antenna in the posion in
the sky where you expect to nd the
satellite.

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 programmes or the
wrong programmes 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!
