Configure DiSEqC to "DiSEqC off" will result in none commands at all, hence no change at the multiswitch. So, if
changing from e.g. 2/B position to "DiSEqC off" will result in the multiswitch still set to 2/B - after a general power
failure resulting in both the multiswitch and the TDcH power cycles then will the multiswitch start up in default e.g.
1/A resulting in wrong position
→
no signal at the TDcH!
In addition to the DiSEqC settings, the menu also shows the (default) values of the (Local-Oscillator-Frequency)
LOF Low:
Local Oscillator Frequency for the low band Frequencies
LOF High:
Local Oscillator Frequency for the high band Frequencies
LOF Switch:
Border frequency between low and high band
Note:
The LOF frequencies can be adjusted to the requirements of the LNB.
