Which action is part of verifying that the digital set-top terminal is functioning correctly?

Verifying that the digital set-top terminal is functioning correctly involves multiple assessment steps, and authorizing the set-top terminal through dispatch plays a crucial role in this process. When a digital set-top terminal is installed or serviced, it's essential to ensure that it has been properly authorized with the service provider's system. This authorization allows the device to access the correct channels and services as intended.

If the set-top terminal isn't authorized, it may appear to be non-functional even if it is physically in good condition. Thus, contacting dispatch to complete this authorization is a necessary action in the overall verification process. This step ensures all systems are go for the terminal to provide the services it's designed for.

While the other actions listed, such as rebooting the device, checking the power supply, and testing the remote control, are important troubleshooting steps in the process, they can only be effectively evaluated once the set-top is authorized. Therefore, ensuring the authorization is completed is foundational to confirming that the digital set-top terminal is indeed operational and can deliver the expected performance to users.
