Having issues programming a MGM 120-32 3S

If you get the beeps according to the manual (3, then 1, then 2) it should be set to the radio. I would not count on the times as they say in the manual, just wait for the beeps. I have a couple MGM controllers, and have had quirky things happen with transmitter programming. If all else fails, reset to default (factory) settings and start over... got me working correctly on a couple occasions.
