• Slide the switch to the appropriate position for your operating system (Mac or Win/Android).
• For Windows users, extra keycaps are provided to replace the Mac-specific keys (e.g., Command, Option) for a familiar layout. Use the included keycap puller to swap them.

5. Operating the Keyboard

5.1. Backlight Control

The Keychron K6 features dynamic RGB backlighting with multiple effects:

• Press the dedicated light effect key (usually located in the top-right corner) to cycle through different RGB lighting modes.
• To change RGB colors (for certain modes), press "Fn1" + Right Arrow key.
• To adjust backlight brightness, press "Fn1" + "F5" (decrease) or "Fn1" + "F6" (increase).
• To turn off the backlight, press "Fn1" + "F5" repeatedly until the backlight is off.

To disable auto-sleep mode, press "Fn1" + "S" + "O" for 4 seconds until the backlight flashes, indicating the mode has been toggled.

6. Maintenance

Proper maintenance ensures the longevity and performance of your Keychron K6 keyboard:

• Cleaning Keycaps: Use a soft, damp cloth to wipe down the keycaps. For deeper cleaning, use the provided keycap puller to remove keycaps and clean them with mild soap and water. Ensure they are completely dry before reattaching.
• Cleaning Switches: Use compressed air to remove dust and debris from between the switches. If your model is hot-swappable (like the Gateron G Pro Brown Switch variant), you can carefully remove switches for cleaning or replacement.
• Battery Care: Avoid fully draining the battery frequently. Charge the keyboard when the battery indicator is low.
• Storage: When not in use for extended periods, store the keyboard in a cool, dry place.

7. Troubleshooting

Here are solutions to common issues you might encounter:

• Keyboard Not Connecting via Bluetooth:
  • Ensure the mode switch is set to "Bluetooth".
  • Check if the keyboard is paired with another device. Try unpairing from other devices or switching Bluetooth channels (Fn1 + Q/W/E).
  • Ensure your device's Bluetooth is enabled and discoverable.
  • Try restarting both the keyboard and your device.
• Input Lag in Wireless Mode (especially for gaming):
  • For competitive gaming, it is recommended to use the keyboard in wired USB Type-C mode to minimize latency.
  • Ensure there are no strong wireless interferences nearby.
• Backlight Not Working or Dim:
  • Check battery level; low battery can affect backlight brightness.
  • Adjust brightness using "Fn1" + "F6".
  • Cycle through lighting modes using the dedicated light effect key.
• Typing Discomfort / Wrist Strain:
  • The Keychron K6 has a relatively high profile. It is highly recommended to use a wrist rest for ergonomic comfort, especially during long typing sessions.
  • Adjust the keyboard's feet to find a comfortable typing angle.
• Keys Not Responding:
  • Ensure the keyboard is properly connected (wired or Bluetooth).
  • Check for debris under the keycap or switch.
  • If your model is hot-swappable, try reseating the switch for the non-responsive key.
  • Perform a factory reset (refer to the Quick Start Guide for specific key combinations, typically Fn1 + J + Z for 4 seconds).
