4. Operating Instructions
4.1 Basic Usage
The K500-B94 functions as a standard wired keyboard. Simply connect it to your computer, and it will be ready for use. The 94-key layout includes a numeric keypad and function keys accessible via the 'Fn' key.
4.2 RGB Lighting Control
The keyboard features various pre-set RGB lighting effects. You can cycle through these effects using specific key combinations (refer to the software or quick start guide for exact key combinations). For advanced customization, including 16.8 million colors, brightness, speed, and custom profiles, use the MACHENIKE K500 software.
4.3 Hot-Swapping Switches
The K500-B94 supports hot-swapping of 3-pin mechanical switches. To replace a switch:
- Gently pull the keycap off the switch using a keycap puller.

- Replace the keycap.

4.4 Multimedia and Function Keys
The keyboard includes 18 multifunctional keys. These functions are typically accessed by holding down the 'Fn' key and pressing the corresponding F-row key or other designated keys. Refer to the keycap legends for specific functions (e.g., volume control, media playback, application shortcuts).
5. Maintenance
5.1 Cleaning the Keyboard
- Disconnect the keyboard from your computer before cleaning.
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the keycaps and chassis.
- For dust and debris between keycaps, use compressed air or a small brush.
- Avoid using harsh chemicals or abrasive materials that could damage the keyboard's finish or keycap legends.
5.2 Keycap and Switch Replacement
As the keyboard features PBT double-shot keycaps and hot-swappable switches, individual components can be replaced if damaged or for customization. Always use appropriate tools (keycap puller, switch puller) to avoid damaging the keycaps, switches, or PCB.
6. Troubleshooting
- Keyboard not responding: Ensure the Type-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
- Specific keys not working: If a single key is not responding, it might be a faulty switch. Utilize the hot-swappable feature to replace the switch.
- RGB lighting issues: If the RGB lighting is not functioning as expected, ensure the software is correctly installed and updated. Check the lighting settings within the software.
- Numeric Keypad not working: Some compact keyboards require a function key combination (e.g., Fn + NumLock) to activate or deactivate the numeric keypad. Consult the keyboard's quick start guide or software for specific instructions.
- Unexpected behavior: Try restarting your computer. If issues persist, consider reinstalling the keyboard software or checking for driver updates.
