Press and hold the Set Button at the base of the RemoteLinc2 until the LED starts flashing green (takes about 3 seconds)
The Insteon address is on a sticker on the back of the RemoteLinc2.
After the nodes are added to the ISY press the set button on the RL2 twice to quit linking mode.
There is something missing here, but I assume it would just be telling us to enter the address, without dashes, because with dashes, as printed, it returns an error that the address is not formatted correctly; nonetheless, I enter the address, and nothing happens.
Further, after pressing the set button twice, the green light only flashes differently; it doesn't seem to quit linking mode.
