Ernie,
I believe what he's saying that he's trying to set the decoders in the manner as mentioned on page 32 of the manual, but in doing so the the whole unit is "locking up". Nothing will work (including volume control) and the only means by which he can reset it, is by doing a "Ferranti" reset . . . cycling the power. (Don't think he meant to imply, "pulling the plug out the wall" was in the manual).
For info.
1). The RX-V2400RDS manual can be found
here. (3.34Mb)
2). No idea what the "U" stands for, but "RDS" is for Radio Data System; details of which begin on page 40.
