Review on Upgrade Your Security with Crimestopper SPLCD52 2-Way Paging Replacement FM-FM LCD Transmitter by Owen Houser

IF YOUR TRANSMISSION IS INTERRUPTED, TRY THIS FIRST! The remote seems to need a reboot and the only way to do it is to turn off the power. Turning it on or off doesn't help. You must either let the remote's battery drain, or open the remote and cut the red wire and then plug it back in. Then add the remote control to your alarm/starter and it should work now.
