2) Code Rate
Also known as Viterbi ratio. It defines the ratio between the number of data bits
and actual transmission bits (the difference corresponds to the control bits for
error detection and correction).
It permits to choose between 1/2, 2/3, 3/4, 5/6 and 7/8.
3) Symbol Rate
It is possible to choose between the following values: from 2000 to 45000 kbauds.
When selecting the option appears the current value, in order to modify it enter a
new value through keyboard when appears the data enter symbol appears on the
upper left corner screen.

4) Polarization
It affects to the signal reception in the SAT band (satellite). It allows to select the
the signal polarisation among Vertical/Right (vertical and circular clockwise) and
Horizontal/ Left (horizontal and circular counterclockwise) or, to deactivate the
polarization (
OFF
5) Sat Band
Selects the High or Low frequency band for satellite channel tuning.
6) LNB Low Osc.
Sets the LNB low band local oscillator.
7) LNB High Osc.
