Hey Starbuck,
This manual is not too different from most manuals these days. You can learn buttons from your other remotes and then learn multiple inputs from many other remotes for the same button on the ICON remote. That turns the plain old "Learn" into a "Macro." Basically you go into to the learn section and learn the first key, say, the power on button from your Plasma, then the screen on the ICON will update and you can hit the button called macro (or something like that), then press OK and the screen will tell you that it is ready to learn another key. Now press the power button for the DVD to learn that button. Repeat this pattern for each new input that you want this particular key on the ICON to perform.
Here is where it gets funny - the X10 stuff. First of all, the ICON remote only sends out infrared (IR) signal. It does not send out the typical RF (radio frequency) that most of your X10 stuff uses. In order to use the ICON remote out of the box to control X10 stuff, you need to use an Infrared Controller (IR543). Yup, that is quite a bummer for most all X10 people that buy this remote. When you get this unit, then go into your device codes and change the code for, say, AUX1 to 0998 - that is the code for the X10 IR stuff. I think channel up is on, channel down is off, volume up is bright, volume down is dim, use the numbers for the module number, and the house code is set on the IR543.
Here is a twist that I have not gotten to work yet and I am anxiously awaiting X10modder's response to one of my posts on this site. He has presented a mod to the ICON remote in which you soldier in a small board from a different X10 learning remote (like the UR74A). This is an easy mod because X10modder's instructions are great - if you have a spare UR series remote. My problem is that when I did it, it did not work for me. I should point out that he says to set the device code to 0999 for the RF signals. My main problem here, other than it did not work for me, was what house code is the unit set to? My house is set up on housecode J. I changed everything over to housecode A to see if it would still work, but no luck.
I agree that it would be nice to have an icon for the X10 unit. There is an identical remote to this under the Philips name (

As far a memory goes, I do not know how much this thing has onboard, but I will tell you that I have programmed a ton of stuff into it and have not hit that wall yet. This is in sharp contrast to the UR74A which seemed to have a very little amount of memory for what I was using it for.
