This manual explains how to install the required driver software (满意办公 V4.5 or V5.1) and start the Lenovo function‑key driver so the keyboard works on Windows 98, 2000 and XP. It also describes the three programmable function keys and the soft‑shutdown key built into the keyboard.
The guide shows how to configure each function key via the task‑bar icon, create custom schemes, and how to disable or exit the function‑key driver when it is no longer needed. This manual is written in Chinese.
