Which device is activated by manual on and responds to radar interrogation?

Explanation:
A radar-responsive distress beacon that is manually activated to aid in location by radar is used in this scenario. The device, known as a Search and Rescue Transponder (SART), is turned on by a manual switch, and when it receives a radar interrogation, it sends back a distinctive radar signal. This reply appears on the interrogating radar as a recognizable pattern (usually a series of dots or a circle), helping rescuers determine the position of the emergency beacon. Other devices mentioned perform different functions and do not respond to radar interrogations, so they would not be activated this way.
