Operation

Battery Level Inquiry

Press the key combination FN + BackSpace. The backlight will turn off, and number keys 1-0 will light up to indicate the power level:

• 1 light: 10% power
• 1-2 lights (red): 10-20% power
• 1-5 lights (yellow): 10-50% power
• More than 5 lights (green): Over 50% power

In wireless mode, if the battery is detected to be 3.0V or lower, the device will shut down. When connected via wired charging, it can be restored to normal use. If the battery voltage is greater than 3.3V, it can be used normally. If the battery is 3.5V or lower, the light will be forced to turn off (buttons will still function), and the low voltage indicator light will flash slowly (1-second frequency).

Leaf Spring Gasket Structure & Five-layer Filling

The F75 features a leaf spring gasket structure with an integrated silicone gasket for better optimization of resilience. Combined with a five-layer internal filling (sandwich cotton, under-shaft pad, voice actor pad, sound-absorbing base cotton, mold silicone base pad), it provides enhanced stability, a softer, and more bouncy typing experience, significantly reducing noise.

Hot-swappable Design

The keyboard is designed with customized shaft seats, allowing users to easily swap out switches without soldering. It supports most three-pin and five-pin mechanical shaft bodies, offering customization and repair flexibility.

PBT Keycaps

The F75 comes with wear-resistant two-color injection molded PBT keycaps. The surface is dry with fine texture, and the characters are high-definition. PBT plastic offers superior durability and resistance to shine compared to ABS plastic.

Maintenance and Care

To ensure the longevity and optimal performance of your FREEWOLF F75 keyboard, please follow these guidelines:

• Cleaning: Use a soft, dry cloth to clean the keyboard. For deeper cleaning, you may remove keycaps using the provided keycap puller and clean with compressed air.
• Temperature: Avoid exposing the keyboard to extremely high or low temperatures. The recommended operating temperature is -45°C to 50°C.
• Disassembly: Do not attempt to disassemble the keyboard yourself. Unauthorized disassembly may cause damage and void the warranty.
• Impact: Avoid violent impact or dropping the keyboard.
• Liquids: Keep the keyboard away from liquids. Spills can cause severe damage to internal components.
• Voltage: Ensure the keyboard is used within the specified working voltage of 4-5.0V.

Troubleshooting

If you encounter issues with your F75 keyboard, refer to the following common problems and solutions:

• Keyboard not responding:
  • Ensure the Type-C cable is securely connected in wired mode.
  • For 2.4G or Bluetooth modes, check if the keyboard is powered on and sufficiently charged.
  • Try reconnecting the 2.4G receiver or re-pairing the Bluetooth connection as described in the Setup section.
  • Switch between connection modes (FN+Q/W/E) to see if the issue is mode-specific.
• Indicator lights not working:
  • Check battery level (FN+BackSpace). Low battery may force lights off.
  • Ensure the keyboard is not in sleep mode. Press any key to wake it up.
• Keys not registering or double-typing:
  • This keyboard is hot-swappable. Try removing and re-inserting the affected switch using the provided shaft remover.
  • If the issue persists, try replacing the switch with one of the spare shafts provided.
• Backlight not changing:
  • Ensure you are using the correct key combinations (FN+PgDn, FN+Tab, FN+Arrow keys) to adjust modes, colors, and brightness.
• Keyboard enters sleep mode too quickly:
  • The keyboard has a light sleep mode (automatic light off after 2 minutes of no operation) and a deep sleep mode (after 30 minutes). This is normal power-saving behavior.

User Tips

• Customization: Take advantage of the hot-swappable design to experiment with different switch types to find your preferred typing feel.
• RGB Effects: Explore the various RGB lighting modes and customize them to match your setup or mood using the FN key combinations and the metal knob.
