Our new Dex finally arrived! Yeah! After 3 months of fighting with insurance it's about time. So I started it up and put in the code for the old transmitter which she is wearing. In other words, both receivers are supposed to be picking up the one transmitter. The new one is in the 2 hr start up but it is showing out of range when the old one, sitting next to it, is not. Any ideas? Just the usual wonkiness? Is there any reason the new one would have less of a range? As far as I know the only difference between the 2 is the share technology.
