Initial settings

displayed continuously, or whether they are to be removed again approximately three seconds after programme changeover..

This setting can be made differently in TV mode and radio mode.

Default:

TV mode

“Off“.

 

Radio mode

“On“.

To call the initial setup menu for radio, the receiver must be switched into radio mode before being switched off. Then call the initial setup menu in the usual way.

LED brightness

Here you can increase the brightness of the LED display. This may be necessary, for example, if bright light is beaming down on the receiver and the LED displays are no longer easy to read. In this case set the display to “High“ setting.

Factory preset: Low

Remote control handset

The receiver contains command sets for Kathrein remote controls with both 24 and 26 keys. The remote control included with the receiver has 26 keys and this is the predefined command set on delivery. Therefore leave this setting unchanged as “26 keys“ (factory preset).

Oscillator frequency

The satellites radiate their programmes in a frequency range that satellite receivers are unable to process. In the receiving system (known as the LNB - Low Noise Block converter or LNC - Low Noise Converter) this frequency is converted into a lower frequency that can be processed by satellite receivers.

The satellite transmission frequencies lie in the following ranges:

10700 ...

11700 MHz

Low-band

11700 ...

12750 MHz

High-band

The receiver‘s input frequency range, however, lies in the range: 920...2150 MHz.

Conversion of the higher frequencies into a lower frequency is achieved with the aid of the oscillator frequency (LO frequency). Various oscillator frequencies are used for the conversion according to the satellite frequency range and type of sys- tem.

For Astra and Eutelsat receiving systems, this is generally 9.75 GHz (9750 MHz) for the lower frequency band (low-band) and 10.6 GHz (10600 MHz). for the upper frequency band (high-band). Older receiving systems still operate in the low-band region with 10 GHz oscillator frequency.

The receiver calculates the frequency onto which it needs to tune by subtracting the oscillator frequency from the satellite transmission frequency stored for each programme.
