just received two new MS16A's and I had a MS14a that I though wasn't working. All don't transmit but they do detect as indicated on the top LEDS. Press the manual on and off keys - both don't send. Verified this by checking through my 1132CU (Smarthome) computer interface. I have a keychain remote and palm remote - both transmit perfectly.

I can see maybe one not working but all three? What could be going on? I have a wireless router that I turned off - still same results.

These devices transmit on frequency A1 = is default from factory.
The receiving device must also be set to A1 = to test the devices.
These M14a and M16a are ON/OFF switches ONLY.
Problem could be in the receiver and not the senders.
