Reduced gain 1 to 10 dB: The lna should be left at max gain while mixer and/or IF gain is reduced.
My two cents are that it's better to play with the multiple stage gains when possible and raise the LNA gain only when necessary, since it's before the VHF2/VHF3/UHF/L-band bandpass and if you have strong signals in other bands you could get intermods virtually everywhere.
