6. Maintenance and Care
To ensure the longevity and optimal performance of your DIERYA DK61SE keyboard, follow these maintenance guidelines:
- Cleaning: Regularly clean the keycaps and the keyboard surface with a soft, dry cloth. For deeper cleaning, you may use a slightly damp cloth with mild soap, ensuring no liquid enters the keyboard.
- Keycap Removal: The double-shot keycaps are designed for durability. If you need to remove them for cleaning or customization, use a keycap puller to avoid damaging the keycaps or switches. Gently pull straight up to remove.
- Storage: When not in use, store the keyboard in a clean, dry environment away from direct sunlight and extreme temperatures. Detach the USB-C cable for easier storage and to prevent cable damage.
