Ghost Controls Standard 5-Button Remote Transmitters are authentic original equipment for Ghost Controls Gate Opener Systems. These 5 button remotes include two buttons for activation of your gate opener systems. If you only have one gate opener system, you can use a second remote to teach the second button to also operate your only gate opener system. If you have two different Ghost Controls gate opener systems, the two activation buttons can independently operate each system. The third button is used when "Learning" a new remote into your system from an existing programmed and working remote. The "Test" button quickly triggers the Gate Opener System to beep to indicate status of gate opener system battery. The "Party" button enables or disables patent-pending PartyMode on the gate opener system to keep your gate opener for extended periods of time without requiring you to turn-off or disable your gate opener system.
