SX88 - Minimum Symbol Rate ?

Hi, greetings to all.

I would like to ask who has this receiver which is the minimum Symbol Rate value that can be set.
Does Octagon SX88 receive DVB S2 signals with Symbol Rate lower than 1 MS/s ? (for example transmissions with Symbol rate of 300 KS/s = 0.3 MS/s)

I thank you for the answer.
