Operating Instructions
The RK104 keyboard offers a unique typing experience and several functional features:
- Typewriter Feel: The mechanical switches provide a distinct tactile bump and audible click, emulating the experience of a classic typewriter. This feedback is designed to enhance typing accuracy and speed.
- N-Key Rollover (NKRO): This feature ensures that every keypress is registered, even when multiple keys are pressed simultaneously. This is particularly beneficial for fast typists and gaming. The keyboard supports switchable 6-key and full-key rollover modes. To toggle between 6-key rollover and N-key rollover, press the FN key simultaneously with the PRTSC SYSRQ key (often labeled N=6).

- Adjustable Stand: The keyboard is equipped with an adjustable knob stand located at the rear. Rotate these knobs to customize the keyboard's angle, allowing you to find an optimal ergonomic position that reduces wrist strain during extended typing sessions.

Maintenance
Proper care will ensure the longevity and performance of your RK104 keyboard:
- Cleaning: Use a soft, dry cloth to wipe the surface of the keyboard. For deeper cleaning, use a can of compressed air to remove dust and debris from between the keycaps.
- Keycap Removal: The included keycap puller can be used to carefully remove keycaps for cleaning or replacement. Gently pull the keycap straight up to avoid damaging the switch.
- Avoid Liquids: Do not expose the keyboard to liquids. In case of accidental spills, immediately disconnect the keyboard from your computer and allow it to dry completely before reconnecting.
- Storage: When not in use for extended periods, store the keyboard in a clean, dry environment away from direct sunlight.
Troubleshooting
If you encounter any issues with your RK104 keyboard, please refer to the following common solutions:
- Keyboard Not Responding:
- Ensure the USB cable is securely connected to both the keyboard and the computer.
- Try connecting the keyboard to a different USB port on your computer.
- Test the keyboard on another computer to determine if the issue is with the keyboard or the original computer's setup.
- Keys Not Registering (Ghosting):
- Verify that N-Key Rollover is enabled. Press FN + PRTSC SYSRQ to toggle the N-Key Rollover mode.
- Ensure no debris is lodged under the affected keycaps. Use the keycap puller to remove and inspect.
