MegaCode series digital transmitters. Each transmitter comes with a unique ID code that is factory programmed. There are over 1,000,000 ID codes.
The receiver is programmed by sending a signal to it from the transmitter(s). This stores the transmitter's code into the receiver's memory. The receiver will retain its memory even without power. The receiver will activate only from these "memorized" transmitters.
The red LED on the face of the transmitter will glow when the unit is activated.
