The Stinger 390GED21V is a single-button visor garage door opener remote designed as a compatible replacement for legacy Genie fixed-code systems using 12 trinary DIP switches at 390 MHz. Built for straightforward, dependable operation, it works with Genie receivers and operators that use the classic 12-switch code format (switch positions typically marked as “+”, “0”, and “–”). This makes it a practical replacement part for older residential or light commercial Genie installations where a like-for-like remote is needed without changing the receiver or adding adapters.
Programming is simple and does not involve a learn button: open the remote and set its 12 internal DIP switches to match the switch positions in your opener’s receiver or an existing working remote, then test operation at the door. The Stinger 390GED21V transmits on 390 MHz and is intended for fixed-code Genie 12-switch systems only; it is not compatible with Genie Intellicode or other rolling-code technologies, nor with different frequencies. Typical use cases include replacing lost or failing GT90-era Genie remotes and adding an extra visor transmitter for multi-vehicle households. For safe operation, verify your door’s safety reversal system after programming and ensure the remote is used within the opener manufacturer’s guidelines.
