MFU Problem, Help Please!!!
 

Ok, so, the MFU is in the Scania, no lights hooked up, just the speaker...

Powered it all up....then the fun begins, pressing the "set" button for 1 sec, it's supposed to flash while I program it to my TX, problem is, it don't flash,it just flashes once then stays on, can't program TX :confused:

Also, when I powered it up for the first time, shouldn't it run then shut down when I press the set button?

BTW, My radio is a Futaba 4EX FM 4 Ch.

What have I done?? :confused::confused:
