6.1 Cleaning

Regular cleaning helps maintain the performance and appearance of your keyboard.

• Disconnect the keyboard from your computer before cleaning.
• Use a can of compressed air to remove dust and debris from between the keycaps.
• Wipe the keycaps and the aluminum surface with a soft, slightly damp cloth. Avoid using harsh chemicals or abrasive materials.
• For deeper cleaning, keycaps can be carefully removed using a keycap puller (not included) and cleaned separately. Ensure they are completely dry before reattaching.

6.2 Storage

When not in use for extended periods, store the keyboard in a cool, dry place away from direct sunlight and extreme temperatures. Protect it from dust by covering it or storing it in its original packaging.

• Keyboard Not Responding: Ensure the USB cable is securely connected to both the keyboard and the computer. Try a different USB port. Restart your computer.
• Keys Not Registering or Double-Pressing: This can sometimes be resolved by cleaning the switches with compressed air. If the issue persists, ensure your keyboard's firmware is up to date via the Cooler Master Portal software.
• RGB Lighting Issues: Check the on-the-fly lighting controls (Fn + F1-F8) to ensure the desired mode and brightness are selected. If using software, verify settings there. Ensure the keyboard's firmware is current.
