To clean your keyboard, disconnect it from all power sources. Use a soft, lint-free cloth to wipe down the acrylic frame and keycaps. For deeper cleaning, remove keycaps using the provided keycap puller and use compressed air to clear debris from between switches. Avoid using harsh chemicals or abrasive materials.

The Phantom 81 V3 features a full-key hot-swappable PCB, allowing you to easily change switches without soldering. Use the included switch puller to carefully remove switches.

- Keyboard not responding: Ensure the keyboard is charged. Check the connectivity mode (Wired, 2.4GHz, Bluetooth) and ensure it matches your device's connection. Try reconnecting the USB cable or re-pairing Bluetooth.
- RGB lights not working: Verify that the backlight is enabled using the FN key combinations. Check software settings if custom profiles are in use.

- Bluetooth connection unstable: Ensure the keyboard is within range of your device. Avoid interference from other wireless devices. Try unpairing and re-pairing the keyboard.
- 2.4GHz connection issues: Ensure the USB receiver is securely plugged in. Try a different USB port. Avoid placing the receiver near large metal objects that may cause interference.
