7.1 Switching Between Modes

The K68 keyboard supports dual mode connectivity. To switch between 2.4G wireless and Bluetooth modes, use the designated switch or key combination on the keyboard (specific key combination not provided, typically Fn + a number key or a dedicated switch).

The keyboard includes multimedia function keys. These are typically accessed by holding down the "Fn" key and pressing the corresponding function key (F1-F12 or other designated keys). Refer to the keycap legends for specific multimedia controls.

7.3 Hot-Swappable Switches

The K68 features full key hot-swappable mechanical switches, allowing you to easily change switches without soldering. This enables customization of your typing feel. To replace a switch:

1. Gently pull out the keycap using a keycap puller.
2. Use a switch puller to carefully remove the mechanical switch from the PCB.
3. Align the pins of the new switch with the holes on the PCB and press firmly until it clicks into place.
4. Re-attach the keycap.

7.4 Anti-Ghosting

The keyboard supports 19-key rollover, meaning up to 19 keys can be pressed simultaneously without conflict, ensuring accurate signal processing, especially during fast-paced gaming or typing.

8. Maintenance

8.1 Cleaning the Keyboard

• Disconnect the keyboard from your device before cleaning.
• Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the keycaps and keyboard surface.
• For deeper cleaning, keycaps can be removed (refer to Section 7.3) and washed with mild soap and water. Ensure they are completely dry before reattaching.
• Use compressed air to remove dust and debris from between the keys.

8.2 Battery Replacement

When the keyboard's performance degrades or it stops responding, it may be time to replace the AAA batteries. Follow the steps in Section 6.1 for battery installation.

9. Troubleshooting

• Keyboard not responding: Check if the batteries are correctly installed and have sufficient charge. Ensure the power switch is ON. Re-establish the 2.4G or Bluetooth connection.
• 2.4G wireless connection issues: Ensure the USB+Type-C receiver is securely plugged into your device. Try plugging the receiver into a different USB port. Ensure the keyboard is within the 10m transmission range.
• Bluetooth connection issues: Make sure Bluetooth is enabled on your device. Forget the keyboard from your device's Bluetooth settings and attempt to pair again. Ensure your device's Bluetooth version is 5.0 or higher (for Windows 8 or higher).
• Keys not working correctly: Check if any debris is lodged under the keycap or switch. If a switch is faulty, it can be hot-swapped (refer to Section 7.3).
