When connecting the radar device, what must be done to avoid damage?

To avoid damage to the radar device, it is essential to connect the antenna to the counting unit before powering on the device. This sequence is crucial because powering on the counting unit without the antenna properly connected can lead to electrical issues and potential damage to sensitive components within the radar system.

The radar system is designed to operate with both the antenna and the counting unit working in conjunction. If the counting unit is powered without the antenna being securely connected, it may cause the system to malfunction or even result in permanent damage due to incomplete circuits or electrical feedback.

Connecting the antenna first ensures that the radar is set up correctly to measure and interpret speed data, allowing for precise and safe operation. This procedure also adheres to recommended guidelines for the proper installation and use of radar devices in speed measurement applications.
