Shenzhen test center Cell Phone Jammer For Teachers has become an indispensable tool in the test center, escorting the information security of the test center. But if we do not use the equipment correctly, there will be poor results, or even an accident in the examination room. Correct use of mobile phone signal jammer in Shenzhen examination room: The effective shielding range of the signal jammer in the examination room will be different in different use scenes. This is closely related to the field strength of the signal on site. The shielding range of mobile phones of different standards at the same site is not necessarily the same; the factors that affect the shielding range include but are not limited to: the distance from the base station, the orientation, the presence of obstacles, the wall material of the site building, and the interference of the mobile phone jammer. Installation height, installation specifications, etc.; cell phone jammer
Each antenna has a frequency band identification, which must correspond to the frequency band identification on the host one-to-one. Cell Phone Jammer For Teachers Before turning on, make sure that each antenna is connected reliably. It is never allowed to turn on the phone without connecting the antenna; the surface temperature of the mobile phone jammer is about 40-50 ℃ after working for a long time, which is normal. If the surface temperature is too high, please turn off the power, and try to contact your local dealer or agent; the normal installation height is 1.8 meters to 2.5 meters, try to choose a place where there are no obstacles between the target shielding area. The wall-mounted installation requires the antenna to be vertically upward. When placed on the desktop, the antenna can be folded 90 degrees and then vertically upward. There should be no AC power lines or other audio and video lines within 0.2 meters of the antenna. The mobile phone signal jammer in the examination room adopts a special advanced technological approach to develop new products according to the needs of the market. It can automatically form a shielding magnetic field within a specified range, so that mobile phones cannot be dialed or accessed, thereby achieving the purpose of compulsory banning of mobile phones. .
