3. Function Key Combinations (Fn)

Due to the compact 61-key layout, many functions are accessed via the Fn key in combination with other keys. The secondary functions are often indicated on the keycaps.

On some compact keyboards, the arrow keys share functions with other keys (e.g., I, J, K, L). To use them as arrow keys, you may need to press Fn simultaneously or toggle a specific mode. If your arrow keys are not responding as expected, try pressing Fn + Right Shift or Fn + Ctrl (right side) to toggle the arrow key mode, or refer to the specific keycap legends for arrow key activation.

Maintenance

1. Cleaning

To clean the keyboard, disconnect it from your computer. Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. For keycaps, you can gently remove them (if hot-swappable) and clean them separately. Avoid spraying liquids directly onto the keyboard.

2. Battery Care

The keyboard features a smart power-saving function that puts it to sleep after 60 seconds of inactivity to conserve battery. To prolong battery lifespan, avoid fully discharging the battery frequently. Recharge when the low battery indicator appears.

Troubleshooting

  • Check if the 2.4G USB receiver is securely plugged into your computer.
  • Verify the keyboard battery has sufficient charge.

  • Try cycling through lighting effects using Fn + \|.
