If your RK908 model is hot-swappable, you can change mechanical switches without soldering.

Remove Keycap: Use the keycap puller to gently pull the keycap straight up.
Remove Switch: Insert the switch puller into the clips on the side of the switch, squeeze, and pull straight up.
Install New Switch: Align the pins on the new switch with the socket holes on the PCB. Press down firmly and evenly until the switch snaps into place.
Test: Plug the keyboard in to test the key before replacing the keycap.

Warning: Ensure you use 3-pin or 5-pin switches compatible with the PCB. Do not force switches in if the pins are bent; straighten them gently first.

1. Unboxing and Initial Setup

The manual begins with the physical inspection of the package. Inside, users find the RK908 keyboard, a USB-C charging cable, a 2.4GHz wireless dongle (on some versions), a keycap puller, and a quick-start guide. The first instruction is to charge the keyboard fully for at least 2–3 hours using the USB-C port. A flashing red LED indicates low battery, while a steady green light (or off) signals a full charge. The manual warns against using fast chargers above 5V/1A to avoid damaging the battery controller.

B. 2.4GHz Wireless Mode

This mode offers a low-latency connection ideal for gaming.

Retrieve the Receiver: Locate the small USB receiver stored on the back of the keyboard.
Plug In: Insert the USB receiver into an open USB port on your computer.
Switch Mode: Turn the toggle switch to the "RF" or "2.4G" position (or press FN + R depending on specific hardware revision).
The keyboard should connect automatically within seconds.

5. Power Management & Charging

Charging: Connect the USB-C cable to a 5V power source. While charging, a LED indicator usually turns red (or breathes). When fully charged, it turns green or turns off.
Battery Life: Battery life depends heavily on RGB brightness and connection mode. Bluetooth mode consumes less power than 2.4GHz mode.
Auto-Sleep: To save power, the keyboard will enter sleep mode after approximately 5-10 minutes of inactivity. Press any key to wake it up (it may take 1-2 seconds to reconnect).
