Operating Instructions
RGB Backlighting and Key Customization
The Air75 V2 supports RGB backlighting and extensive key customization through QMK/VIA software.

Maintenance
Keycaps
The keycaps are made from Double-shot PBT material, known for its durability and resistance to shine and fading. This ensures that characters remain clear and legible even after extended use.
Cleaning
To clean your keyboard, gently wipe the keycaps and frame with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials. For deeper cleaning, keycaps can be carefully removed using a keycap puller (not included) and cleaned separately. Ensure the keyboard is powered off and disconnected before cleaning.
Troubleshooting
Connectivity Issues
- Keyboard not responding: Ensure the keyboard is charged. Check the connection mode switch (Bluetooth, 2.4G, USB-C) is set correctly. For wireless modes, ensure the keyboard is paired or the 2.4G receiver is properly inserted.
- Lag or dropped keystrokes: For wireless connections, try moving the keyboard closer to the receiver or device. Ensure there are no strong interference sources nearby. Update keyboard firmware if available.
- Bluetooth pairing failure: Ensure the keyboard is in Bluetooth pairing mode. Remove previous pairings from your device's Bluetooth settings and attempt to pair again.
Key Functionality
- Incorrect key output: Verify the operating system switch (Windows/Android vs. macOS/iOS) is set to match your device. If keys are remapped, check your QMK/VIA settings.
- Non-responsive keys: If a specific key is not working, it may be due to a faulty switch. As the keyboard is hot-swappable, try replacing the switch with a known working one.
