5. Setup Instructions
Follow these steps to set up and program your OLLGEN USB Double Foot Switch Pedal Control:
- Download Software: Obtain the "Elfkey" programming software. This software is typically provided on the included CD or can be downloaded from the manufacturer's website. Ensure you download the version compatible with your operating system (Windows, Mac, Linux, Android).
- Connect Foot Pedal: Plug the USB cable of the foot pedal into an available USB port on your computer.
- Install and Run Software: Install the "Elfkey" software on your computer and launch it.
- Program Functions: Within the "Elfkey" software interface, select the desired function for each pedal from the list of available options. You can assign single keys, key combinations, mouse clicks, or multimedia controls.
- Save Settings: After configuring the pedals, click the "Save" button within the software to store the settings onto the foot pedal's internal memory.
Note: Once the foot switch is configured and settings are saved, it can be moved to a different computer and used without the "Elfkey" software, as the programmed functions are stored directly on the device. Multiple foot pedals can be connected to one PC, but each must be programmed individually.
