Naim NDX ground switch - floating or chassis

I have read the numerous previous threads on this, (so apologies for raising this again!) but just wanted a quick clarification.

Current system is LP12/Stageline/NDX/282/Hicap/250. Until recently, I had a Linn Karik CD player connected to the 282 so the NDX ground switch was set to floating. I have now disconnected the CD player from the 282, so from what I've read on here and in the NDX manual, am I right in thinking the NDX ground switch should now be set to chassis?

Thanks in advance for your help.
