I have an omega gdo (model 4500) we had an power outage and now both transmitters won't work. I did have to manually open door but it has been returned to automatic. The wall mount is operating. Code lights say 4 and 8. manual doesn't address this issue and vendor is closed till tues.( 4th of july) no obstructions. The only problem is the transmitters not working. By the way, new batteries too. Thank you for any feedback
