Phone signal jammers are mainly aimed at various places where the use of mobile phones is prohibited, such as various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, government, finance, prisons, public security, and military centers.
How to use phone signal jammer:
1. Select the area that needs to cut off the phone signal of the mobile phone, and place the cutter on the desktop or wall in this area.
2. After the installation is complete, turn on the power of the disconnector and turn on the power switch.
3. After the equipment is connected, press the power switch and the disconnector to work. At this time, all the mobile phones that are turned on at the scene are searching for the network, and the base station signal is lost. Both the caller and the caller cannot establish a call connection.
