J.Rowland Is it possible to shut off the display

No, you can neither shut off the display nor dim it, as far as I know. As for the
balance control, there is none. They are using the remote from a different
(earlier) product, one that did offer a balance control.

Tony, how do you do that on the Concentra? Also, don't you have balance control on the Concentra?

Part of the problem may be that JRDG never deigned to publish a manual for the Concerto.

No kidding? My dealer said no, but he may have been wrong and if it is a subtle change, I would have assumed it wasn't there at all. So is there a way to know it's back to center other than by ear?
