1. Press the 'power switch' after the instrument starts, the default detection mode is 'magnetic field radiation intensity' detection, more than 2 milliseconds Gauss alarm, at this time can long press the 'detection mode switch' do not Let go, after about 2 seconds, you can switch to 'electric field radiation intensity' detection.

2. Hold the Radiation Detector in your hand, point it at the object to be measured and approach it slowly until it is in physical contact with the object to be measured. The closer you are to the object, the faster the alarm frequency.

3. Use the Radiation Detector to change the angle and position of the instrument in relation to the object being measured as much as possible during the measurement process, so that accurate readings can be obtained.

4. If the power is switched off during Radiation Detector use, the reading should be reset to zero when in "magnetic field radiation intensity detection" mode.

5. Pressing the "alarm setting" for a short period of time will turn the alarm sound on or off.
