How to Check a Solar Radar Speed Sign After Receiving It

Do you need to wait until the solar radar speed sign is installed on the road before checking whether it works properly? Not necessarily.

If the unit already has power when you receive it, you can first turn on the power switch and check whether the display starts normally. Then, simulate a vehicle passing in front of the radar to check whether the radar detects the moving target and displays the speed.

The video below shows the basic connection and startup process, including how the radar speed sign enters its working state after the power is switched on.、

Start by Checking the Display

If the unit already has power, simply turn on the power switch.

Wait for the system to start, then check whether the speed display lights up normally. A properly illuminated display indicates that the unit has been powered on and started.

However, a lit display alone does not confirm that the speed measurement function is working. The radar detection function should also be tested.

Simulate a Vehicle Passing to Test Speed Detection

A radar speed sign uses radar to detect moving vehicles and displays the detected speed on the screen.

After the unit starts, simulate a vehicle passing in front of the radar and observe whether the radar detects the movement and displays a speed reading.

If the radar detects the moving target and the display shows the corresponding speed, the basic functions of the unit—including startup, radar detection, and speed display—can be considered to be working properly.

Connect the Solar Panel After the Basic Test

If the unit will be powered by a solar panel, the solar panel can be connected after the basic power-on and speed detection tests are completed.

Connect the solar panel cable to the corresponding port on the unit and make sure the connection is secure.

If the unit already has power when it arrives, connecting the solar panel is not required before the initial test. It is more practical to check the basic functions first and then connect the solar panel for solar-powered operation.

What If the Unit Does Not Work Properly?

If the unit does not start after turning on the power, first check the battery level and power switch.

If the display lights up normally but no speed is shown when simulating a vehicle passing, the radar detection function may need to be checked.

If the problem remains after these basic checks, you can take photos of the unit or record a short video of the test and send it to us. Our team can help check the issue based on the actual situation.
