If you're using a 22khz switch, then you'd leave the
DiSEqC switch setting blank, and specify the appropriate switch setting for the 22khz switch.
The Fortec receivers do not indicate R & L for circular polarization... it only shows H & V, regardless of polarization type. Observation in my Fortec Lifetime
Classic receiver indicates that it shows 'V' for 'R' and 'H' for 'L'.
