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 posit ion (“ EX T ”).
Fig. 4: DC-power supply socket (1),slide switch (2)
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 anoth er way of supp ly .
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.
Y ou ca n use non -re chargeable and rec har gea ble 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.

SAT-Navi menu
To align a satellite dish, please take the following steps:
1. Select a satellite from the list
Fig. 6: SAT-Nav menu
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.
Fig. 7: Transponder
Î 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.

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 Err or Rate
Q: Signal Quality (Bar Graph)
Fig. 9: Signal
With this Information and the acoustic signal, you can fine-tune the antenna to the
opti ma l po s it i on.
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.
Î To ex it the Sate llite Nav iga tor function, just press OK.
3.1.1 Short Circuit Protection
