Providing that you have SAM on in the Configurator, an easy way to switch SAM on and off from the remote: press TONE once, SOURCE once, then to turn SAM on and off, rotate clockwise (the dial, not yourself ;-)) for ON and anti-clockwise for OFF. I don’t like having a dedicated button on the remote for SAM, and this is a good workaround. In this mode, you can still use your iPhone/iPad remote for volume control.
