RRFU and Ch Clear

There was a time, on the Net3 Radio Remote Focus Unit, while in Park, that if you had a range of channels active, you could clear all by pressing "Channel, @, Enter, Enter" to clear all parked channels.

After 2.3.1, (or possibly sooner and I never noticed) this command syntax throws an error.  Thus you now have to list those channels, or all the conventionals with "Ch., 1 thru XX, @, Enter. do this

Or am I losing my mind
