Basic Adjustment of the Polarmount Aerial
Installation Menu
With the unit switched off, press and hold down the ¢V/H button and switch the unit on. The display indicates "INSTALL".
The preceding diagram shows an overview of the installation menu. After approx. 3 seconds, the display indication chan-
ges to "INPUT | A". With the ¢</ > buttons, you can |
switch to "INPUT | B". Select the desired aerial input, then |
press the ¢MODE button.
You pass to the next menu item where the frequency of the local oscillator 1 (lower LNC frequency range) will be asked. The display indicates "LOC OSC1". Pressing one of the
¢</ > buttons switches to the frequency indication. Select the desired value with the ¢</ > buttons (hold down the corresponding button to let scroll the values at high speed).
button
ches to the 2nd oscillator frequency (upper LNC frequency range). The display indicates "LOC OSC2". Enter the fre- quency as described above.
Next, you can...
–if necessary, proceed by selecting INPUT B with the
¢MODE button.
–store in memory the settings made by pressing the
¢MEMORY button (this will close the installation menu).
–abort the installation menu by pressing the ¢P/F button. The old settings are restored and the installation menu is
closed. Aborting the menu with the ¢P/F button is possi- ble from any menu item.
With system 3, the oscillator frequencies for both inputs must be entered. The inputs A and B a permanently allocated:
Input A: Frequency band 11 GHz.
Polarizations V1, H1.
Input B: Frequency band 12 GHz.
Polarizations V2, H2.
In this case, it is not possible to use the ¢V/H button to directly switch during normal operation between the inputs A and B, as explained in chapter "¢V/H – Selecting Vertical/Horizontal Polarization and Input A/B". It is possible to freely select between the polarizations V1, H1 (input A) and V2, H2 (input B). Switching between the inputs then is per- formed automatically.
Adapting the Polarizer
If you should have selected a system with magnetic or motor- driven polarizer, this must also be preadjusted, as there are many different types available.
How to proceed:
At first, the aerial must be positioned at the satellite. We recommend the powerful Astra satellite. This will be ex- plained in the following example.
Select the programme position number 1 (Astra satellite, 19° East, ARD) on the receiver. This programme position is pre- programmed with horizontal polarization H1. The default impressed current for the polarizer is to be optimized by per- forming the following steps:
Press the ¢ button to switch the receiver into the manual aerial positioning mode. Press the ¢< button to run to limit 1, then press the ¢> button to search the Astra 19° East satellite. If the picture of ARD appears on the picture screen, the correct satellite has been found.
If you should not be able to find this programme, change the polarity of the connections of the magnetic polarizer on the
The display indicates, for example:

SIGNAL IIIIIIIIIIIII
The polarizer current can be adjusted by pressing the
¢</ > button. The correct adjustment is situated between the black and white spikes. To avoid multiple polarization
rotations, the smallest required value should be adjusted. Press the ¢MODE button once again.
The display indicates:

I99 SKEWXALL STEREO
SIGNAL IIIIIIIIIIIII
Store the setting with the ¢Memory button. All programme positions preprogrammed with H1 now will successively be set to this optimum value.
Repeat the same steps for stations with vertical polarization V1.
For this, select programme position 3 (RTL in Germany). Press the ¢V/H and then the ¢MODE button.
