Safety Notes
Turn off the receiver or any used power supply before installing, to avoid short-circuit.
Installation and repairs to the equipment may only be carried out by technicians observing the current
VDE guidelines. No liability will be assumed in the case of faulty installation and commissioning.
Before opening the device, pull the mains cable or remove the power supply, otherwise there is a
danger to life. The same is true when you clean the device or perform work on the connections.
Power feeding cables as well as feeder lines may not be damaged or clamped by objects of any kind.
Avoid exposure of the equipment to direct sunlight and to other heat sources (e. g. radiators. other
electrical devices, chimney, etc.). Absolutely avoid that cables come near any source of heat (e.g.
radioators, other electrical devices, chimney, etc.)..

Chapter 2: Power supply
2 Power supply
There are three ways to establish the power supply of the device:
2.1.1 External power supply
Connect the external power supply to the DC-power supply socket (1).
Make sure the slide switch (2) is in the position (“EXT”).
Fig. 4: DC
(1),slide switch (2)
ower supply socket
2.1.2 Satellite receiver
The SAT-Navi can be operated by delivering the power remotely from a satellite receiver or
multiswitch (which may be supposed to be connected to the LNB after searching the Satellite).
The receiver/multiswitch should be able to deliver 600mA of current to the LNB!
Make sure the power supply selector is in the position (“EXT”).
Connect the LNB/IF input of the satellite receiver to the DC power supply input (8) of the SAT-Navi
If the SAT-Navi does not power up or switches off when trying to search satellites, the current
delivered by the receiver may be insufficient. Please use another receiver or another way of supply.
2.1.3 Internal batteries
Make sure, you have inserted fitting batteries into the compartment in the right direction.
Put the Power Supply Selector in the lower position (“BATT”) to activate battery operation.
You can use non-rechargeable and rechargeable batteries in AA size.
Low Voltage
If the voltage of any power source is lower than 13.3V, the red low voltage LED lights up
Take care, that the input voltage is always higher than 13.3V.
If you are using rechargeable batteries, switch off (to “EXT”) the device when the red LED lights up to
prevent the cells from total discharge.

Searching of a signal
3.2 SAT-Navi menu
To align a satellite dish, please take the following steps:
1. Select a satellite from the list
2. Choose if you want to search the satellite with the default transponder (FREQ. DEFAULT) or with
other transponders (FREQ. LIST). Please prefer (FREQ. DEFAULT), because the identification of the
satellite is more precise for this option.
If you choose (FREQ. LIST), you can select the transponder in the following menu .
Now, the Satellite and Transponder is chosen and the device tries to lock on a signal from the desired
satellite.

Chapter 3: Operation
3. Please move now the Satellite dish antenna slowly until you clearly hear the buzzer noise. The SAT
Navi has logged-in and reckognized the wanted Satellite. The following other informations are
displayed now too:
P: Signal Strength (in dBµV)
BER: Bit Error Rate
Q: Signal Quality (Bar Graph)
Fig. 9:

bit error rate
With this Information and the acoustic signal, you can fine-tune the antenna to the optimal position.
The frequency of the acoustic signal is linked to the signal quality. So you can search the satellite and
fine-tune the position also without seeing the display of the Sat Navigator.
To exit the Satellite Navigator function, just press OK.
3.2.1 BER – bit error rate
The BER (bit error rate) indicates the system reserves of a Satellite dish unit. The BER value should be
as high as possible.
good acceptable bad
1.0 e-8...e-7
1.0 e-6...e-4
The lowest BER-limit value lies at 2.00e-04, in order to achieve an error-free signal. However with this
a.m. limit-value the system does not have any more reserves and should therefore lie well above this
min. level.
2.0 e-4
1.0 e-3...e-1
3.2.2 Signal level

Signal level measured at
an antenna wall outlet

The signal level must neither be too low, nor too high.
3.2.3 Short Circuit Protection
If there is a short circuit on the LNB input, the LNB power will be cut off and there will be the message
“Short c. detected” in the display.
After you have removed the cause for the short circuit, it appears the message “Short c. restored” and the
LNB Power is switched on again.
3.3 Activating the DiSEqC control
If necessary, the respective LNB can be activated via DiSEqC.

3.4 Light menu
In the Light Menu, you can switch the background light of the LCD on or off.
For always being up to date, a software update of the SAT-Navi can be carried out via the serial RS-232
interface. Since most modern PCs don’t have an RS-232 port any more, a USB adapter has to be used. It
is included in the programming set SZU 22-00 (the programming set must be ordered separately).
4.1 Connecting the SAT-Navi to the PC
To update the software, the following steps are required:
4. Connect the adapter to the update port of the SAT-Navi located in the battery compartment.
