Operating Instructions

QMK/VIA Customization

The Womier RD75 Pro supports QMK and VIA firmware, allowing for extensive customization of key functions, macros, and lighting. To utilize these features:

• Download the latest VIA software and the corresponding JSON keymap file for the RD75 Pro from the official Womier website or VIA's website.
• Connect the keyboard via USB-C cable to your computer.
• Open the VIA software. The keyboard should be automatically detected.
• Use the VIA interface to remap keys, create complex macros, and configure RGB lighting effects. Changes are applied in real-time.

RGB Lighting Control

The keyboard features dynamic RGB backlighting with over 40 preloaded effects. Specific key combinations (often involving the 'Fn' key) are used to cycle through lighting modes, adjust brightness, and change colors. Refer to the quick start guide included with your keyboard for specific key combinations.

Battery Management

The 8000mAh battery provides long-lasting performance. To charge the keyboard, connect it via the USB-C cable to a power source. The RGB lighting may indicate charging status (e.g., a specific color or animation). Disconnect the cable once fully charged to preserve battery health.

Maintenance

Disassembly for Customization

The Womier RD75 Pro features a quick-release design for easy access to internal components. To disassemble:

1. Ensure the keyboard is powered off and disconnected from all cables.
2. Gently separate the top and bottom housing components. The ball-catch structure allows for tool-free separation.
3. The magnetic PCB connector simplifies detaching the main board from the case.
4. When reassembling, align the components and press firmly until the ball-catch mechanism secures the housing.

Switch and Keycap Replacement

The hot-swappable sockets allow for easy replacement of switches without soldering. Use the included switch puller to carefully remove switches. Use the keycap puller to remove keycaps. Ensure new switches are aligned correctly before pressing them into the PCB to avoid bending pins.

Cleaning

Regularly clean your keyboard to maintain performance and appearance. Use a soft brush or compressed air to remove dust and debris from between keycaps. For stubborn dirt, gently wipe keycaps with a damp cloth and mild soap solution, ensuring no liquid enters the keyboard's internal components.

Troubleshooting

Q: Why keyboard keys are not sensitive?

A: The keyboard adopts the latest quick disassembly structure. During the transportation of the keyboard, the upper cover and the lower cover of the keyboard may be loose due to bumps in the road. Please check the keyboard according to the following steps after receiving the keyboard:

1. Before using the keyboard, remove the upper cover of the keyboard, and then press the keyboard from top to bottom with both hands, so that the keyboard key switch is completely consistent with the keyboard PCB board.
2. After installing the keyboard cover, press and hold the Fn+END key for 5-7 seconds to restore the keyboard factory settings.

Q: Why is my WIN key not working?

A: In the case of locking the WIN key by pressing FN+WIN, the WIN key cannot be triggered for use. To unlock it, simply press FN+WIN again.

Q: What should I do if I want to customize the buttons and use the macro function?
