3.3 CHERRY MX Silent Red Switches
The keyboard is equipped with CHERRY MX Silent Red mechanical switches. These linear switches are designed for quiet operation, reducing typing noise by approximately 30% compared to standard Red switches. They offer a smooth keystroke with no tactile bump or audible click, making them suitable for environments where noise reduction is important. The switches have a durability rating of over 50 million keystrokes.

4. Maintenance
4.1 Cleaning the Keyboard
To maintain optimal performance and appearance, regularly clean your keyboard.
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the keycaps and casing.
- For dust and debris between keys, use compressed air or a small brush.
- The PBT keycaps are durable and resistant to shine, but avoid harsh chemicals that could damage the legends.
4.2 Keycap Removal
If you need to clean under the keycaps or replace them, use a keycap puller. Gently pull the keycap straight up to avoid damaging the switch stem. When reattaching, align the keycap with the switch stem and press down firmly until it clicks into place.
5. Troubleshooting
5.1 Keyboard Not Responding
- Ensure all cables (main USB-C and interconnect cable) are securely connected.
- Try connecting the keyboard to a different USB port on your computer.
- Restart your computer.
- Check the DIP switch settings on the underside of the keyboard to ensure they are configured correctly for your operating system.
5.2 Macro Programming Issues
- If using FILCO Assist software, ensure the keyboard is directly connected to the PC (some KVM switches may interfere).
- Verify that the macro recording process is followed precisely as outlined in the quick guide or software instructions.
- Some keys (e.g., Esc, CapsLock, Shift, Ctrl, Win, Alt, Fn) may have limited remapping options via hardware macros.
- If hardware macros are not working, try resetting the keyboard to factory defaults using the DIP switches.
5.3 Fn Key Not Functioning
- Check DIP switch settings related to Fn key functionality or remapping.
- If the Fn key has been remapped or disabled via software, use FILCO Assist to restore its default function.
