2. 2.4G Wireless Connection

Locate the 2.4G wireless USB dongle stored in the compartment on the underside of the keyboard. Insert the dongle into an available USB port on your computer.

4. System Modes

The keyboard supports four system modes for compatibility with various operating systems:

• Fn + Q: Windows Mode
• Fn + W: macOS Mode

• Fn + R: Android Mode

For macOS users, if function keys do not behave as expected, press Fn + Esc to toggle the Fn key lock. This may resolve issues with media keys or other function key behaviors.

Maintenance

1. Cleaning

To maintain your keyboard's appearance and functionality, regularly clean the keycaps and chassis. Use a soft, lint-free cloth, slightly dampened with water or a mild cleaning solution. Avoid excessive moisture. For deeper cleaning, keycaps can be carefully removed.

2. Battery Charging

The keyboard is equipped with a rechargeable Lithium Ion battery. Connect the keyboard via the USB-C cable to a power source (computer USB port or wall adapter) to charge. Charging time is typically 2-4 hours. The keyboard can be used while charging. A full charge can provide up to 365 days of standby battery life (usage time varies based on backlight settings and usage frequency).

Troubleshooting

• Keyboard not connecting via Bluetooth: Ensure the keyboard is in pairing mode (Fn + BT1/2/3 key flashing). Check your device's Bluetooth settings to ensure it's discoverable and within range. Remove previous pairings on both the keyboard and device if issues persist, then attempt to re-pair.
• 2.4G Wireless connection issues: Ensure the USB dongle is securely inserted into a working USB port. Try a different USB port. Ensure there is no significant interference from other 2.4GHz devices or USB 3.0 cables nearby.
• Keys not responding or input lag: In wireless modes, ensure the keyboard battery is sufficiently charged. If using 2.4G, try moving the dongle closer to the keyboard or using a USB extension cable. If using Bluetooth, check for interference or try re-pairing. For wired mode, ensure the USB-C cable is firmly connected.
• Backlight not working or inconsistent: Check the battery level. Use Fn + \| to cycle through modes, and Fn + ↑ to increase brightness. If the issue persists, a full charge may be required.
• MacOS function keys not working correctly: Press Fn + Esc to toggle the function key behavior. This often resolves compatibility issues with macOS system preferences.
• Poor battery life or slow charging: Ensure you are using a compatible power source for charging. While the keyboard can be used while charging, heavy usage with full backlighting may slow down the charging process.
