5. Maintenance

5.1 Cleaning

To clean your keyboard, first disconnect it from your computer. Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. For keycaps, you can remove them using the provided keycap puller and clean them separately. Avoid spraying liquids directly onto the keyboard.

5.2 Switch and Keycap Replacement

The Ajazz AK820 Pro features hot-swappable sockets, allowing you to easily change switches without soldering. Use the provided 2-in-1 switch-and-keycap puller for replacement.

  1. Removing Keycaps: Gently hook the keycap puller onto the sides of the keycap and pull upwards.
  2. Removing Switches: Use the switch puller end to grip the top and bottom clips of the switch, then pull straight up.
  3. Installing Switches: Align the pins of the new switch with the holes on the PCB. Press down firmly until the switch clicks into place. Ensure pins are not bent.
  4. Installing Keycaps: Place the keycap over the switch stem and press down gently until it is secure.

6. Troubleshooting

  • Keyboard not responding: Ensure the keyboard is properly connected (wired) or paired (wireless/Bluetooth). Check battery level. Try resetting the keyboard (FN + SPACE BAR).
  • Wireless connectivity issues: Ensure the 2.4GHz receiver is securely plugged in or Bluetooth is enabled on your device. Try re-pairing the device.
  • Backlight not working: Check backlight brightness settings (FN + ↑/↓) and ensure it's not turned off (FN + X).
  • Keys not registering: If specific keys are not working, try removing and re-inserting the switch for that key, as it might not be seated correctly.

7. User Tips

  • For optimal battery life, turn off RGB lighting when not needed or use wired mode.
  • Experiment with different backlight effects and colors to personalize your setup.
  • Utilize the programmable software to create custom keybinds and macros for enhanced productivity or gaming.
