What cannot a factory-trained technician perform when working with electrical/telecommunication equipment?

A factory-trained technician is qualified to perform various tasks associated with electrical and telecommunication equipment, but there are specific limitations based on their training and the regulations governing such work. The correct response highlights that a factory-trained technician should not be involved in onsite assembly and installation in certain contexts, particularly when those activities require a broader scope of expertise that goes beyond factory training.

Onsite assembly and installation often necessitate a comprehensive understanding of the entire system, including interactions with existing infrastructure and compliance with local regulations, codes, and safety standards. This level of expertise typically falls under the responsibilities of licensed professionals, such as electricians or telecommunication installers, who have undergone extensive training and certification, ensuring they are equipped to handle complex installations that may involve significant risks or regulatory compliance issues.

Initial calibration and testing, adjustment during startup, and modification of components can often be executed within the scope of a factory-trained technician's abilities, as these tasks are usually more focused on ensuring that the equipment functions as intended after it has already been designed and integrated into a system.
