4.1. Keyboard Layout and Features
The HUO JI CK608 features a compact 61-key layout, offering essential functionality while saving desk space. It includes:

- Hot-Swappable Sockets: The keyboard is designed with hot-swappable sockets, allowing you to change switches without soldering. This enables customization and easy replacement of faulty switches.
- Ergonomic Design: The keycap design is scientifically stair-stepped to provide maximum comfort and reduce hand fatigue during extended use.

5. Maintenance
Proper maintenance ensures the longevity and performance of your keyboard:
- Cleaning: Regularly clean the keyboard with a soft, dry cloth. For dust and debris between keycaps, use compressed air. For stubborn grime, lightly dampen a cloth with water or a mild cleaning solution (avoid harsh chemicals) and wipe the keycaps. Ensure no liquid enters the keyboard.
- Spill Prevention: Avoid spilling liquids on the keyboard. If a spill occurs, immediately disconnect the keyboard from your computer, turn it upside down to drain, and allow it to dry completely before reconnecting.
- Keycap Removal (Optional): If you need to clean under the keycaps or replace switches, use a keycap puller to gently remove keycaps. Be careful not to damage the switches or stabilizers.
- Storage: When not in use for extended periods, store the keyboard in a clean, dry environment away from direct sunlight and extreme temperatures.
