I can change the ABC switch and immediately get info from my neighbors sensor. I have used the other 2 switch options on both displays and the sensor but I get nothing with the sensor next to the displays. I use Duracell batteries and have used 2 different sets. I've done all the reset stuff. I've tried calling, but like my sensor, your call in system is broke also. My sensor is a 06004M that was part of the 02032B bundle.
