How to use

Charge the mouse via the USB Type‑C port before first use. Switch between RF 2.4 GHz, Bluetooth 5.1 and wired mode using the device selector (refer to the user manual for exact button placement). Adjust DPI and polling rate using the external DPI and polling buttons on the mouse for on-the-fly changes. For additional remapping, macros and advanced settings (LOD, DPI steps, polling-rate options) install Keychron Engine on your computer and follow the software prompts to save profiles.

Recommendations

For the best balance of runtime and responsiveness, use 1K polling rate during extended work sessions and switch to the higher polling rate (up to 4000 Hz) for fast-paced gaming. Maintain firmware and Keychron Engine updated and keep the sensor surface clean for optimal tracking.
