Tuning Frequency
The DVB-S/S2 card tunes by the L-band frequency rather than the transponder frequency or local oscillator
value. The L-band frequency is the difference between the downlink transponder frequency “Sat Freq:” and
the LNB local oscillator frequency “LO Offset:”. The IRD will calculate the actual frequency in which the
card tunes; saving the user time and possible miscalculation errors.
Local Oscillator Offset
The Local Oscillator Offset provides preset values that can be selected using the List mode. Any valid
Local Oscillator Offset value can be entered using the Manual mode.

Offset Mode:” then press the button.
