Midsummer June is about to usher in the high school entrance examination and college entrance examination. In order to ensure the quality of the examination, many schools have already started preparing for the examination room in advance.

However, installing a cell phone jammer is not something that everyone can do. So, what should I pay attention to when installing the mobile phone signal jammer? In fact, the installation itself will be relatively simple, but a few small details before the installation determine the subsequent use of the mobile phone signal jammer. For example, the environment near the installation site. And the installation height.
In order to ensure the best effect of the signal, in general, the installation of more than one meter and less than three meters has the best effect. The cell phone signal jammer is relatively small and can be fixed on the ceiling or wall with ordinary screws. Of course, it can also be used directly on a table or something. However, in this case, the effect is not very good. After installation, check to see if everything is connected well, and if there is any problem with accessories such as power supply. Finally, plug the power adapter into the adapter power socket of the machine, and directly connect the 220V power supply. Next is the test machine. If there is any problem, you can contact the manufacturer as soon as possible if you find it during the testing process. As long as it is produced by a regular manufacturer, it will usually be solved in time.
