4. Maintenance

To ensure the longevity and optimal performance of your HP GK400F Mechanical Gaming Keyboard, follow these maintenance guidelines:

• Cleaning: Regularly clean the keyboard to prevent dust buildup. Use a soft, dry cloth for general cleaning. For deeper cleaning, a can of compressed air can remove debris from between keys.
• Dust and Spill Resistance: The keyboard features a mechanical metal panel designed to be dust and spill resistant. While it offers protection against minor spills, it is not fully waterproof. Avoid submerging the keyboard in liquids. In case of a spill, immediately disconnect the keyboard from your computer and allow it to dry completely before reconnecting.
• Keycap Removal: If necessary, use the included key puller tool to carefully remove keycaps for thorough cleaning. Reattach keycaps by aligning them with the switch stem and pressing down gently until they click into place.
• Storage: When not in use for extended periods, store the keyboard in a clean, dry environment away from extreme temperatures.
