The cell phone jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. The scanning speed can cause garbled interference in the message signal received by the cell phone, and the cell phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station.The cell phone will show the phenomenon of searching the network, mobile phone no signal and no service system.
The following is the usage of cell phone jammer.
First of all,select the area that needs to cut off the cell phone signal, and place the cut-off device on the desktop or wall in this area.
Secondly,after the installation is complete, turn on the power of the disconnector and turn on the power switch.
Thirdly,after the equipment is connected, press the power switch and disconnector to work. At this time, all the cell phones turned on at the scene are searching for the network, and the base station signal is lost. Both the caller and the called cannot establish a call.
