This could be because one of your transmitters is out of range and isn’t communicating with the display. This could be because:

1. The Chorus is out of range of the transmitter. You can try moving the display to a position where it is closer to the transmitters or to where it gets a better radio signal.

2. The batteries could be running low in the transmitter; please insert new batteries.

To see the status of your wireless sensors go to: » Installation » Status  If the status is green then the signal is fine; red shows a problem.
