No guarentee, but here are the EFCs for a 8042. I'll assume that your OFAs can do keymoves.
Tap the device button that setup code 0784 is assigned to. Then, repeatedly:
1) Press Setup until 2 blinks
2) Enter 994
3) Tap Setup
4) Enter an EFC from the below list (if the remote needs 5 digit EFCs, prepend 2 zeros)
5) Tap the button to assign the function to.
The remote should blink twice.
