Precaution of using Rongxin desktopphonesignaljammer

1.The farther the installation location is from the base station, the farther the shielding distance is. When the base station signal field intensity of the installation point is -75dBmv, the maximum distance from the shielding center is about 40 meters. The larger the signal field strength of the base station, the smaller the shielding distance. When the signal field strength of the base station is greater than -35dBmv, the maximum distance from the shielding center is only 1-2 meters.

2. Shielding range refers to the circular area centered on the machine. The shielded signal is sent out by the host and propagates outward from strong to weak. Large places should choose the appropriate number and location of installation, the use of honeycomb installation, so that the shielded signal uniform distribution.

3.The human body, objects, walls and so on block the transmission of shielding signal, when using, the distance between the machine and the human body should be kept at least 1 meter, and try to avoid the obstruction.

4.The machine should be installed in a cool, dry place, avoid direct sunlight and rain and fog invasion.
