Midsummer June will usher in the senior high school entrance examination and the college entrance examination. In order to ensure the quality of the test, many schools started the preparations for the test room early. In the process of preparation, there is a very important thing, that is to install a mobile phone signal jammer. However, not everyone can install a cell phone jammer. So, what should you pay attention to when installing a mobile phone signal jammer? In fact, the device itself is relatively simple, but a few small details before the device determine the subsequent use of this mobile phone signal jammer. For example, the environment around the device location. And device height.
In order to ensure the best signal effect, it is generally best to install at least one meter and less than three meters. The cell phone signal jammer is relatively small and can be fixed to the ceiling or wall with ordinary screws. Of course, it can also be used directly under the table, etc. However, in this case, the effect is not very good. After the installation is completed, check whether the parts are connected correctly, and whether the power supply and other accessories can be successful. At first, unplug the power adapter from the adapter power socket of the machine and connect it directly to the 220V power supply. The next step is to test the machine. If you find any problems during the testing process, you can contact the manufacturer as soon as possible. As long as it is consumed by regular manufacturers, it will usually be processed in time. If you encounter a pit manufacturer, it is recommended to go back to the manufacturer directly. So here, we recommend manufacturers like Shenzhen Dexin Electronics. Not only reliable reputation, but also reliable quality. And solve problems in a timely manner to ensure that the interests of customers are not harmed.
