What is the primary function of a user manual?

The primary function of a user manual is to guide users on how to operate or troubleshoot a product. User manuals are designed with the specific purpose of providing clear, step-by-step instructions that help users understand the features and functions of a product, along with troubleshooting tips for common issues. This guidance is crucial for ensuring that users can effectively and safely utilize the product as intended.

In addition to operational guidance, manuals often include important safety information, maintenance tips, and FAQs to help users navigate challenges. This focus on usability means that the content is structured in a way that prioritizes the user's ability to interact with and derive value from the product.

While other options may provide useful information in different contexts—such as historical context or product comparisons—they do not fulfill the core purpose of a user manual, which is primarily about assisting users in practical, immediate ways.
