Switch on your jammer

Note:(Switching on is not allowed before the all antenna have been linked, otherwise the equipment is easy to be damaged.)

install all antenna at first.


Input the 220V AC power, Turn on the “RED Switch”.

Press the on/off green button.


Turn off your jammer

Turn off the “RED Switch”.

Move away 220V AC power from the main machine .

The jammer is out of work.


Question and answer

Does jammer interfere the other electronic equipment to work in normal condition?


No. Because the electromagnetic signal sent by jammer are totally used in the band that regulated by government and just have interception effect to cell phone communication.


Is jammer harmful to the human body and cell phone?


Please do not need to worry about it. The intensity of electromagnetic signal sent by jammer is in compliance with the national standard of environmental electromagnetic wave health. The signal sent by jammer is relatively small and no harmful to human body according to the testing result. Meanwhile, this device just damage the receiving condition to the cell phone and makes the normal connection between cell phone and base station impossible. Therefore, no damage will occur on cell phone itself.


The shell of jammer will become hot after working for some times. Does the long working time will damage the machine itself?


It is very normal. When designing, we are thinking of taking use of the conductivity of metal shell to help the heat sinking during our designation. By this way, the machine can be kept in good working condition for long time.
