Handset Transmitter

The handset LED will give one short flash when button is pressed momentarily. If button is held down the LED will light again after 2 seconds for 2 seconds, and extinguish until button is released and repressed. The handset contains unique information distinguishing it from other transmitters. It also contains a set of "random" rolling codes programmed into the ECU before leaving the factory. Each time the handset is pressed a different code is transmitted to the ECU. If handset is operated more than four times outside the vehicle range (6 meters) or power supply is removed, it will be necessary to resychronize handset and the ECU by pressing the handset three times within range and within 5 seconds.
