2. Backlight Settings

Adjust the keyboard backlight by holding the Fn key and pressing the Left Arrow or Right Arrow keys. There are three lighting modes: Steady On, Breathing, and Off.

3. Key Switches and Keycaps

The LOFREE Flow2 uses Cloud Switch Series low-profile mechanical switches. These switches are hot-swappable, allowing for customization. To remove keycaps, use the included keycap puller. For larger keycaps like the spacebar, pull from both sides separately to prevent stabilizer damage. To remove switches, use the included switch puller, aligning it with the switch clips and gently wiggling it upward.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the keyboard surface. For deeper cleaning, remove keycaps and use compressed air to clear debris.
• Battery: The keyboard features a 3000mAh battery. Recharge via the USB-C cable when the battery indicator shows low power. Avoid extreme temperatures.
• Storage: Store the keyboard in a cool, dry place away from direct sunlight and excessive moisture.

Troubleshooting

• Keyboard not responding: Ensure the power switch is on and the correct connection mode (Wired, 2.4G, or BT) is selected. For wireless modes, check battery level.
