Which describes how RADAR needs to be set up at different detection sites according to legal standards?

The correct answer emphasizes the importance of accuracy in RADAR operation at different detection sites. According to legal standards, RADAR equipment must be verified for accuracy at each location where it is deployed. This ensures that the readings and data collected are reliable and can be used confidently in enforcement actions. Regular checks help to maintain the integrity of the equipment and the data, taking into account that various environmental factors or installation differences at each site could impact performance. Therefore, confirming accuracy at each site is key to compliance with legal standards and helps uphold the credibility of the RADAR technology used in law enforcement.

In contrast, the other options suggest a lack of necessary precautions that could potentially compromise the effectiveness and reliability of the RADAR. Setting it up randomly would fail to account for critical factors that can affect accuracy. Relying only on initial setup without subsequent verification ignores the possibility of equipment drift or miscalibration. Finally, having no additional checking would not meet the stringent legal requirements for accurate enforcement measures.
