How to use a radar detector

Radar Detection Instrument Instructions for Use

I. Working Principle

Radar The radar detector is an active life detector that emits continuous electromagnetic wave signals at a certain frequency to scan a certain space. When continuous electromagnetic waves encounter obstacles, part of them are reflected back, and the other part continues to propagate forward through the obstacles. If the obstacle encountered is stationary, the returned electromagnetic wave signal will not change, but once a moving target is encountered, such as various fluctuations caused by human life activities, such as breathing and heartbeat, the reflected electromagnetic wave signal will have a certain frequency shift according to the moving speed. By filtering and detecting the frequency shift signal, it is possible to determine whether there is a living body.

II. Operation and Use

1. Unboxing Operation : Open the main unit battery cover, insert the battery into the main unit, close the battery cover, and turn on the main unit power.

2. Instrument Placement : Select a suitable location to place the life detector, with the detection surface ( bottom of the detector ) facing the area to be measured.

3. Turn on Pad and connect it to the main unit. The firefighter holds the display controller, and the distance from the radar detector main unit is at least 10 meters. No one else is allowed to interfere with this area.

4. Turn on Pad On the radar terminal, enter the system, set the detection parameters, and start detection.

III. Precautions

1. High-voltage lines, fluorescent lights, water, and large metal objects will interfere with detection.

2. In addition to people with vital signs, other free-living organisms and moving objects in the detection area will affect the detection accuracy.

3. Select the appropriate detection method according to the specific environment, and correctly place the radar detector to improve the overall performance of the radar detector 的整体性能

4. The distance between the operator and the radar main unit should be greater than the specified distance, and there should be no interference from others in the interval.

5. Determine the approximate location of the target and control the radar's " end distance ” to improve the sensitivity of the radar.

6. Normally exit the radar detection software first, then turn off the radar detector power.

7. Charge the device in time after each use.

8. Radar detector Remove the battery when not in use for a long time.
