3.2 Programmable Rotary Knob

The aluminum rotary encoder can be customized to perform various functions, enhancing your workflow. Through VIA, you can assign it to control:

• Volume adjustment
• Screen brightness
• Zoom in/out
• Brush size in creative software
• Scrolling through video clips or photos
• Backlight hue or brightness

4. Maintenance and Care

4.1 Hot-Swappable Switches

The Q2 Pro features hot-swappable switch sockets, allowing you to easily change switches without soldering. This enables customization of typing feel and sound, and simplifies replacement of faulty switches.

1. Power off the keyboard or disconnect the USB-C cable.
2. Use the provided keycap puller to remove the desired keycap.
3. Use the provided switch puller to gently grasp the switch and pull it straight up.
4. Align the pins of the new switch with the holes on the PCB and press it firmly until it clicks into place. Ensure pins are not bent.
5. Replace the keycap.

4.3 Cleaning

• Keycaps: Remove keycaps using the keycap puller. Clean with mild soap and water, then dry thoroughly before reattaching.
• Case: Wipe the aluminum case with a soft, damp cloth. Avoid abrasive cleaners.
• Between Keys: Use compressed air to remove dust and debris from between the switches.

4.4 Double-Gasket Design and PCB Stabilizers

The Q2 Pro features a double-gasket design with silicone pads between the top and bottom cases to reduce sound resonance. It also includes PCB-mounted screw-in stabilizers for improved stability on larger keys. These components are designed for durability and a smoother typing experience.

5. Troubleshooting

5.1 Connectivity Issues

• Keyboard not connecting via Bluetooth: Ensure the keyboard is in 'BT' mode and in pairing mode (Fn1 + 1/2/3 for 4 seconds). Check your device's Bluetooth settings and ensure it's discoverable. Try forgetting the device and re-pairing.
• Keyboard not recognized in wired mode: Ensure the keyboard is in 'Cable' mode. Try a different USB-C port or cable. Restart your computer.

5.2 Key Functionality Issues

• Keys not responding: If a specific key is not working, try hot-swapping the switch with a known working one to determine if the switch or the PCB is the issue. Ensure the switch is fully seated.
• Incorrect key output: Check the operating system toggle switch (Win/Mac) on the back of the keyboard. If using VIA, ensure the correct keymap is loaded and no accidental remappings have occurred.

5.3 RGB Lighting Issues

• RGB not lighting up: Ensure the backlight is enabled. Check brightness settings. If using VIA, verify lighting settings are correctly configured.

5.4 Firmware Reset

If you experience persistent issues, a firmware reset may resolve them. Refer to the official Keychron website for specific instructions on how to reset or reflash the firmware for your Q2 Pro model.
