Maintenance

Cleaning

Regular cleaning helps maintain the keyboard's performance and appearance. Use the provided keyboard cleaner brush and cloth to remove dust and debris from between the keycaps and on the surface.

Keycap and Switch Replacement

Utilize the included keycap puller to safely remove keycaps. For switch replacement, gently pull the switch straight up using a switch puller (not explicitly listed as included, but implied by hot-swappable feature and extra switches). Ensure proper alignment when inserting new switches to avoid bending pins.

Troubleshooting

• Keyboard not connecting: Ensure the mode selector is set correctly (BT, 2.4G, or Wired). For wireless modes, check battery level. For Bluetooth, ensure your device's Bluetooth is on and the keyboard is in pairing mode. For 2.4GHz, ensure the dongle is securely plugged in.
• Keys not responding: Check if the keyboard is properly connected. If hot-swappable, ensure the switch is fully seated. Try replacing the switch with one of the spares if available.
• RGB lights not working: Check brightness settings using the functional knob or FN key combinations. Ensure the keyboard is charged.
• Lag or input delay: For wireless connections, try moving closer to the receiver or switching to wired mode for optimal performance.
