What is one of the necessary steps for setting up the TSC but not powering it on?

One of the necessary steps for setting up the Tactical Session Controller (TSC) is to attach the grounding strap to the grounding lug. This step is crucial as it ensures the safety of both the device and the user by preventing static electricity buildup, which can result in damage to sensitive electronic components. Proper grounding also helps to ensure that the device operates correctly by avoiding interference from external electric fields.

In the context of setting up the TSC, performing this grounding step is essential before powering on the device or establishing any connections. It serves as a foundational safety measure that should be prioritized during the setup process. Other options, such as connecting to Wi-Fi or downloading drivers, may occur later in the setup process, and powering up the device itself comes after ensuring that all safety precautions, including grounding, are adequately addressed.
