Misunderstandings in the use of mobile phone signal jammers in the examination room!
The college entrance examination in China is a major event for the people of the whole country. After several years of hard work and hard work, thousands of students have all been tested in one or two days. If they pass the test, they will be able to choose from good universities and good resources. The worse is the situation where the resource opportunity is slightly lacking.

1. The test panel signal monitor will have different effective shielding ranges in different places of use. This is closely related to the signal field strength of the site. Different types of mobile phones may not have the same shielding range on the same site, so the selection should be based on the actual situation.
2. Factors affecting the shielding range include but are not limited to distance, direction, barrier-free objects relative to the base station, wall materials of the site building, installation height of the protective cover, installation specifications, etc. Other factors should also be paid attention to.
3. Each antenna has a frequency band identifier, which must correspond to the frequency band identifier on the main unit, and each antenna must be connected reliably before the shield is turned on, never use the device without an antenna.
4. It is normal for the surface temperature to rise above 40 degrees after shielding for a long time.
5. The normal installation height of the mobile phone signal jammer is 1.8 meters to 2.5 meters, and it should be installed in a position where there are no obstacles between the target shielding area and the target shielding area. If the antenna needs to be vertically upwards in a wall-mounted installation; when placed on a table, the antenna can be folded 90 degrees and then vertically upwards.
6. During use, in order to avoid possible interference to some electronic equipment, the following common equipment should be used to keep 1~2 meters away.
