Every year on such solemn and solemn examination occasions as the high school entrance examination and the college entrance examination, there are always some people trying to fish in troubled waters. Use some dishonorable means. An exam like this should be fair. If some people use some small tricks, in the end, it is likely to cause a series of serious consequences.
In order to protect the vital interests of the candidates, mobile phone signal jammers are a powerful tool in the examination room. Like other important exams, the use of mobile phone signal jammers is also highly valued in the examination room, so many misunderstandings in use must attract everyone’s attention. <a href=”https://www.silencejammer.com/”>signal jammer</a>
Misunderstandings in using signal jammers:
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 at the site. Different types of mobile phones may not have the same shielding range on the same site, so the choice should be based on the actual situation.
2. Factors that affect the shielding range include but are not limited to distance, direction, barrier-free objects relative to the base station, wall materials of site buildings, installation height of the protective cover, installation specifications, etc. Other factors should also be taken seriously.
3. Each antenna has a frequency band identifier, which must correspond to the frequency band identifier on the host. You must ensure that each antenna is connected reliably before shielding is turned on. Never use the device without an antenna.
4. After the shield has been running for a long time, it is normal for the surface temperature to rise above 40 degrees.
5. The normal installation height of the mobile phone signal jammer is 1.8 meters to 2.5 meters. Install it in a location where there are no obstacles between the target shielding area and the target shielding area. If the antenna needs to be pointed up vertically in wall-mounted installation; when placed on a table, the antenna can be folded 90 degrees and then pointed up vertically.
