5. Maintenance

5.1 Cleaning the Keyboard

To maintain optimal performance and appearance:

• Disconnect the keyboard from your computer before cleaning.
• Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps and frame.
• For dust and debris between keys, use compressed air or the included keycap puller to remove keycaps and clean thoroughly.
• Avoid using harsh chemicals or abrasive materials.

5.2 Replacing Switches

The Z-88 features hot-swappable Outemu switches. To replace a switch:

1. Use the keycap puller to carefully remove the desired keycap.
2. Use a switch puller (not included, but often comes with replacement switches) to gently pull the switch out of its socket.
3. Align the pins of the new 3-pin Outemu switch with the holes on the PCB and press firmly until it clicks into place.
4. Reattach the keycap.

5.3 Splash Resistance

The keyboard is designed with splash resistance. While it can withstand minor spills, it is not waterproof. Avoid submerging the keyboard in liquids or exposing it to excessive moisture.

6. Troubleshooting

If you encounter issues with your E-Yooso Z-88 keyboard, please refer to the following common solutions:

• Keyboard not responding: Ensure the USB cable is securely connected to both the keyboard and the computer. Try a different USB port or a different computer to rule out port or system issues.
• Specific keys not working: If only a few keys are unresponsive, try removing and reseating their switches (if you have a switch puller). Ensure no debris is lodged under the keycap or switch.
• Backlight not working or incorrect: Press Fn + PgDn or Fn + -/= to cycle through modes. Adjust brightness with Fn + ↑/↓. If issues persist, try resetting the keyboard with Fn + ESC.
• Windows key locked: Press Fn + WIN to toggle the Windows key lock.
• Intermittent connection: Ensure the detachable Type-C cable is fully inserted and not damaged. Try a different Type-C cable if available.

If these steps do not resolve your issue, please contact customer support.
