The manual guides you through installing the keyboard driver by running the supplied setup.exe program, following the default prompts, and restarting the computer. After installation, a Lenovo function‑key icon appears in the task‑bar, confirming the driver is active.
It then describes how to customize the three programmable function keys, the soft‑power key, and the invoicing key via the Settings dialog. You can select predefined schemes (Office or Multimedia) or create your own, assign applications or commands, and save or delete custom schemes as needed. This manual is written in Chinese.
| Programmable function keys | 3 |

The fourth key launches the invoicing software; if the software is not installed, the system shows a prompt message.
