SkyLink G7M is a remote control for garage door openers that can operate up to 2 garage door openers from the same remote. It comes with a visor clip and a mounting bracket for easy installation in your vehicle or on a wall. The G7M uses a rotary switch to select the brand and frequency of your garage door opener, making it compatible with most brands and models. To program the G7M, simply follow the instructions in the manual. Once programmed, you can use the G7M to open and close your garage door from up to 150 feet away. The G7M also has a built-in LED light that flashes when the signal is transmitted, so you can be sure that your command was received.
