To turn on the backlight for the PROTMEX PT20C, touch the "SNOOZE / LIGHT" sensing area on the top of the signal receiver.

I have two PT20A and want both to use the same outdoor sensor. How can I set the second PT20A to receive that outdoors sensor. SO can two PT20A share share/read the same outdoor sensor ?
