5.3. Gasket Structure

The numpad incorporates a gasket-mounted design, which provides a softer, more flexible typing experience and improved acoustics by isolating the plate from the case. This design contributes to a more comfortable and satisfying feel with each keystroke.

6. Maintenance

6.1. Cleaning

• Use a soft, dry cloth to wipe the surface of the numpad regularly.
• For deeper cleaning, use the provided keycap puller to carefully remove keycaps. Use compressed air or a soft brush to remove dust and debris from beneath the keycaps and switches.
• Do not use harsh chemicals or abrasive materials, as these may damage the numpad's finish or components.

6.2. Switch and Keycap Replacement

• Removing Keycaps: Gently attach the keycap puller to the sides of the keycap and pull upwards evenly until the keycap detaches.
• Removing Switches: After removing the keycap, use a switch puller to grasp the top and bottom clips of the switch. Apply gentle pressure and pull the switch straight up.
• Installing Switches: Align the pins of the new switch with the holes on the PCB. Gently push the switch down until it clicks into place. Ensure the pins are straight to avoid bending.
• Installing Keycaps: Align the new keycap with the switch stem and press down firmly until it is securely seated.

7. Troubleshooting

7.1. Common Issues and Solutions

• Numpad not responding:
  • Check the USB-C cable connection for wired mode.
  • For 2.4GHz wireless, ensure the receiver is securely plugged in and the numpad is in 2.4GHz mode.
  • For Bluetooth, verify the numpad is in Bluetooth mode and correctly paired to your device. Try re-pairing if necessary.
  • Ensure the numpad has sufficient battery charge.
• Backlight not working:
  • Press Fn + Backspace to toggle the backlight on.
  • Adjust brightness using the rotary knob or QMK/VIA software.
• Keys not registering or double-typing:
  • Ensure the switches are properly seated in their sockets.
  • If a specific key is consistently faulty, consider replacing the switch using the hot-swap feature.
• Connectivity issues (lag, disconnections):
  • Ensure the numpad is fully charged.
  • Reduce interference by moving other wireless devices away from the numpad or receiver.
  • Try restarting your computer/device and the numpad.
