Step-by-step explanation:
The document that typically starts the warranty period is the warranty certificate or warranty card that comes with the purchased product. This document is provided by the seller or manufacturer and outlines the terms and duration of the warranty coverage. It serves as proof of purchase and acts as a contract between the buyer and the seller.
For example, when you buy a new smartphone, it usually comes with a warranty card that specifies the length of the warranty period, any limitations or exclusions, and instructions on how to make a warranty claim if needed.
It's important to read and keep the warranty document safe as it can provide protection and potential remedies in case of any defects or issues with the product during the specified warranty period.
