Hi,
To allow me to understand the system better and save me putting annoying questions on the forum could you explain the 
following features;

(a)  the two colored dots to the left of the time display
(b)  the com led 

The reason I ask is that the new Rx was operating perfectly but now has the dots both red and no data is going to the WD's or W underground. I have rebooted to no avail. I assumed it was receiving data from the Tx as it got "W" "D" and then went to the weather screen, but no green lights

I reverted to the original Rx and all is good, so the Tx would appear to be OK 
Thanks
Jim
