Ray,
1. select one of the 6 device positions. 2. Press "learn" 3. press the button you want to learn to. 4. Position the teacher 10-16 inches below the bottom of the learner, and press and hold the button you want the LRC-1 to learn. Wait till the learn led quits flashing, and the green "send" led flashes. You can keep learning a button at a time until your done with the set to the device position. To shut off the learning mode, press "learn" again. To delete one, just press "delete", and the button you want deleted. Deletes will require pressing delete for each one you want, it doesn't stay active for more than one key at a time like the "learn" does.
There are NO preset codes, so if you don't have a teacher, you aren't gonna get a signal programmed in; It's strictly 100% learning.
You'll find that short presses on the teacher will be adequate for most signals. Longer presses work better for repeat signals like volume, but watch it, don't learn too long of a volume signal or you'll get large increases per button press. It takes a bit of finesse and experience to know what works good. To short will yield volume increases so small you can't perceive them, too much will yield like 1/4 rotation moves at a time.
I've found mine would learn some signals other's refused to learn. Oh yeah, there's no magic in those device "names". If you have a a couple remotes that have fewer buttons, you can put two devices on the same device setting, just divide up the buttons in some way you can remember. TV's and VCR's work pretty good to set up this way.
You might also get two different signals learned to one button since the learn time is pretty long, effectively some small macros. It'll take some finesse with quickly going from one teacher button to another.
Hope this helps.
Jim
