Step-by-step explanation:
Step 5 of the procedural text supports the purpose of the text by allowing the phone to detect the Bluetooth speaker so they can be paired. When you activate the pairing mode on the speaker, it enables the speaker to search for and connect to your phone. By bringing your phone close to the speaker and selecting the name of the speaker on your phone's Bluetooth screen, you are establishing a connection between the two devices.
