Had a digital bartec go down on me today, wondering if anyone had any idea as to why. Basically, hand unit and receiver seem to be having difficulty talking to each other beyond 15 ft or so. no combination of antennae, motor cable, fresh batteries etc. would fix it. Communication would drop, so motor would stop working, and when radio signal came back up motor would slowly orient itself to hand unit setting. Job is over, so can't really test whether factory reset will fix it (had new one brought in last second), so I figured I'd come here out of curiosity. Headaches!
