3. Software Installation for Programming: To program the keypad with custom macros or functions, dedicated software is required.
• For Windows Users: The programming software is primarily designed for Windows. You can download the latest version from: https://dl.sayobot.cn/setting.zip.

Operating Instructions

Programming the Keypad

The programming application for the O2L RGB keypad is designed to be user-friendly with an understandable English translation. It allows you to assign various functions to each of the two keys independently.

• Standard Macros: Assign complex key combinations or sequences to a single press.
• Mouse Simulation: Configure keys to simulate mouse clicks or movements.
• Multimedia Controls: Set keys for volume control, play/pause, etc.
• Single Key Assignment: Map any standard keyboard key.

After programming, the settings are stored directly on the keypad's internal memory. This means you do not need to re-program the device when connecting it to a different computer, or if you switch operating systems (e.g., from Windows to macOS or Linux) after initial programming on Windows.

Using the Keypad

Once programmed, the keypad functions as a dedicated input device for your assigned tasks. It is particularly effective for:

• Rhythm Games: Enhance your gameplay in titles like OSU! by assigning specific actions to the two keys for quick and precise input.
• Productivity Macros: Streamline workflows in applications by triggering frequently used commands or text snippets with a single key press.
• Custom Shortcuts: Create personalized shortcuts for any software or operating system function.

Maintenance

To ensure the longevity and optimal performance of your BTXETUEL O2L RGB keypad, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe down the keypad's surface. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid excessive moisture.
• Keycap Removal: Use the provided keycap puller to safely remove keycaps for cleaning or switch replacement. Gently pull straight up to avoid damaging the switch stem.
• Switch Care: The keypad features hot-swappable switches. If a switch needs replacement, carefully pull it out using a switch puller (not included, but often comes with switch sets) and insert a new compatible switch, ensuring the pins align correctly.
• Storage: When not in use, store the keypad in a clean, dry environment away from direct sunlight and extreme temperatures.
• Avoid Liquids: Do not expose the keypad to liquids. Spills can cause internal damage.

Troubleshooting

If you encounter any issues with your O2L RGB keypad, please refer to the following common problems and solutions:

• Keypad Not Responding:
  • Ensure the USB cable is securely connected to both the keypad and your computer.
  • Try connecting the keypad to a different USB port on your computer.
  • Test the keypad on another computer to rule out system-specific issues.
• Programming Software Warning (Windows):
  • As noted in the Setup Guide, Windows Firewall may issue a warning. This is normal. You can safely proceed with running the software.
  • Ensure your antivirus software is not blocking the application. Temporarily disable it if necessary, then re-enable after installation/programming.
• Keypad Not Working on macOS/Linux After Programming:
  • Confirm that the keypad was successfully programmed on a Windows system. The settings are stored on the device itself.
  • Ensure the keypad is properly connected via USB.
• Incorrect Key Output:
  • Re-open the programming software and verify that the desired functions are correctly assigned to each key.
  • Save the settings to the device after making changes.
