What distinguishes a User Manual from an Operator's Manual?

The distinction between a User Manual and an Operator's Manual primarily lies in the target audience and their level of expertise with the product. A User Manual is designed for individuals who may not have specialized training or experience using the product. These manuals often focus on providing clear, step-by-step instructions that are easy to understand for unskilled users, ensuring accessibility to a broad range of customers.

In contrast, an Operator's Manual is aimed at skilled operators who are usually familiar with the equipment or software. This type of manual can include more technical details and may assume a certain level of prior knowledge. It often provides in-depth operational guidance and troubleshooting information suitable for those who are already experienced in handling the specific device or system.

This clear differentiation in purpose and audience highlights why the first option is accurate. The other choices do not effectively capture the essential distinction based on user proficiency and the corresponding writing style employed in each manual.
