This keyboard supports hot-swapping of 3-pin or 5-pin mechanical switches, allowing for easy customization without soldering.

1. To Remove a Switch: Use the provided switch puller tool. Gently grip the switch from the top and bottom, then pull upwards with even pressure until the switch detaches from the PCB.
2. To Install a Switch: Align the pins of the new switch with the holes on the PCB. Ensure the pins are straight to avoid bending. Gently press the switch down until it clicks into place. Do not force the switch if it doesn't go in smoothly; re-align the pins.

5. Maintenance

5.1 Cleaning the Keyboard

• General Cleaning: Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the keycaps and chassis. Avoid excessive moisture.
• Dust Removal: Use compressed air to blow away dust and debris from between the keycaps and switches.
• Deep Cleaning (Keycaps): For thorough cleaning, remove the keycaps using the provided keycap puller. Wash them gently with warm, soapy water, rinse thoroughly, and ensure they are completely dry before reattaching.

5.2 Keycap and Switch Care

• Avoid exposing the keyboard to extreme temperatures, direct sunlight, or high humidity.
• Do not spill liquids on the keyboard. If a spill occurs, immediately disconnect the keyboard and allow it to dry completely before reconnecting.
• When removing or installing switches, apply even pressure to avoid bending the pins.

6. Troubleshooting

If you encounter issues with your keyboard, please refer to the following common problems and solutions:

• Keyboard Not Responding:
  • Ensure the USB-C cable is securely connected to both the keyboard and the computer.
  • Try connecting the keyboard to a different USB port on your computer.
  • Test the keyboard on another computer to rule out a computer-specific issue.
  • Restart your computer.
• RGB Lighting Not Working/Incorrect:
  • Ensure the keyboard is properly connected and powered.
  • Cycle through lighting modes using FN + 0.
  • If using custom settings, ensure the driver software is running and correctly configured.
• Specific Keys Not Registering:
  • Carefully remove the keycap and then the switch for the problematic key.
  • Inspect the switch pins for any bends or damage. Straighten bent pins gently with tweezers if possible.
  • Reinsert the switch firmly, ensuring both pins are correctly aligned with the PCB sockets.
  • Try swapping the problematic switch with a known working switch from another key to determine if the issue is with the switch or the PCB socket.
• Metal Knob Not Functioning:
  • Ensure the knob is clean and free of debris.
  • Verify that no software or system settings are overriding the volume control.

If the issue persists after attempting these troubleshooting steps, please contact HELLO GANSS customer support for further assistance.
