The G3TBX is a 390 MHz remote control designed as a substitute for the Genie GITR-3 3-button model. It features Intellicode technology for secure garage door operation and is compatible with Genie garage door openers that support this frequency and protocol. The remote provides three buttons for standard garage door functions including open, close, and stop commands. This replacement remote maintains the same operational specifications as the original model while offering a reliable alternative for controlling your garage door system.
