3. Operating Instructions
3.1 Hot-Swap Switches
The VGN S99 features a full key hot-swap design, allowing you to easily change mechanical switches without soldering. This enables customization of your typing feel and sound.
3.2 RGB Backlighting
The keyboard is equipped with 16 million color RGB backlighting, offering dynamic lighting effects. You can customize these effects through the VGN HUB software.
3.3 VGN HUB Software
The VGN HUB software allows you to manage and customize various aspects of your VGN S99 keyboard, including key remapping, macro creation, and RGB lighting effects. It supports SMARTSPEED ultra-low latency transmission for optimal performance.

3.4 Battery Life
The VGN S99 is powered by a 6000mAh battery. Battery life varies depending on usage:
- Up to 35 hours with RGB lighting effects turned on.
- Up to 35 days with RGB lighting effects turned off (based on 8 hours of continuous use per day).

3.5 Wireless Transmission
The S99 is equipped with SMARTSPEEDX wireless transmission technology, significantly improving response times. Conventional 2.4G schemes typically have 8-15ms delay, while Smart Speed X achieves less than 2.9ms.

3.6 Internal Structure and Keycaps
The keyboard features a four-layer silencer structure with PO sandwich cotton, IXPE eight-fold foam shaft lower pad, shaft seat cotton, and silicone bottom pad to effectively fill internal space and eliminate cavity sounds. The Gasket leaf spring structure provides a softer feel and cleaner sound.

The keycaps are original height PBT material, using GMK characters for classic reproduction. They feature surface fine sand treatment for a delicate touch and durability, with a thickened keycap wall design for a calmer sound.

4. Maintenance
4.1 Cleaning
To keep your keyboard in optimal condition, regularly clean it using the provided dust cover. For deeper cleaning, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
4.2 Switch Replacement
The hot-swap feature allows for easy switch replacement. Use the two-in-one key puller to carefully remove keycaps and switches. When inserting new switches, ensure they are aligned correctly to avoid bending pins. Note that improper hot-plug operation may damage the switch body. Use spare shafts to replace any damaged ones.
5. Troubleshooting
- Keyboard not connecting wirelessly (2.4G/Bluetooth): Ensure the mode switch at the bottom of the keyboard is set to the correct position. For 2.4G, verify the receiver is securely plugged into a USB port. For Bluetooth, ensure your device's Bluetooth is on and re-initiate the pairing process (FN + 1/2/3).
- Keys not responding: If you have recently hot-swapped switches, ensure they are fully seated and the pins are not bent. Try re-inserting the switch. In wired mode, check the USB-C cable connection.
- RGB lighting not working: Ensure the keyboard is charged. Check VGN HUB software for lighting settings.
- Short battery life: Battery life is significantly reduced when RGB lighting is active. Turn off or dim RGB lighting to extend battery life. Ensure the keyboard is fully charged before use.
