Hi all. After a power outage, my squeezebox duet front light was solid blue, & the controller (which I hadn't used in a while, preferring ipeng via iphone) is stuck on displaying the logitech symbol (actually it goes blank for 3 seconds, then goes back to the symbol), with all function lights lit. I pressed the front button on the receiver before I noticed the state of the controller, & now it's slow blinking red (about 1.5 seconds of red, then 1.5 secs off, then red etc), which I gather is an indication of its being ready to reset it, but how do I do this with the controller apparently malfunctioning?

Ipeng only shows iphone as a player.
I have the duet receiver connected to fios router by ethernet.
