Misunderstandings about using signal jammers in examination rooms
Examination room signal jammers have become an indispensable tool in the examination room to protect information security in the examination room. However, if we do not use the equipment correctly, there will be bad results and even accidents in the examination room. The editor will share with you the correct use of signal jammers in the examination room.
1. When the examination room signal jammer for cell phone is used in different fields, its effective shielding range will be different. This is closely related to the field strength of the field signal. Different types of mobile phones may have different blocking ranges in the same location.
2. Factors that affect the shielding range include but are not limited to: distance and orientation relative to the base station, presence or absence of obstacles, wall materials of on-site buildings, installation height and installation specifications of the shield, etc.
3. Each antenna has a frequency band identification, which must correspond to the frequency band identification on the host. Before opening the shield, you must ensure that each antenna is connected reliably. Never turn on the phone without connecting the antenna.
4. After the shielder has been working for a long time, the surface temperature is about 40~50℃. If the surface temperature is too high, please cut off the power and try to contact a nearby sales store or agent.
5. The normal installation height is 1.8m~2.5m. Try to choose a location without obstacles between the installation and the target shielding area. During wall-mounted installation, the antenna is required to point vertically upward. When placed and used on a desktop, the antenna can be folded 90 degrees and then pointed vertically upward. There should be no AC power cords or other audio and video cables within 0.2 meters around the antenna.
6. During use, in order to avoid possible interference with certain electronic equipment, you should keep at least 1 to 2 meters away from the following commonly used equipment: speakers, wireless microphones, radios, computers, TVs, Wi-Fi routers, etc.
The above is the misunderstanding of the signal jammer in the examination room that the editor of Dazhan Electronics introduced to you today.
