You only do a AUX155 to a device if you're going to teach it the commands from the original remotes. All it clears are preset commands, you still have erase any previously learned commands.

Anyways to program a AUX 155 to a device:

1. press and hold main & ent
2. P-PRO
3. press device key you want to program
4. press AUX device key, always the bottom left device key, no matter what it may have been changed to
5. enter 1 5 5
6. save
7. main
8. main

It has to be done to each device individually.
