How to install and use the signal jammer?

-Step 1:Install the corresponding numbered antennas.

-Step 2：Fix it directly to the wall or ceiling with screws at a height of 1-2 meters or put on the table or cabinet.

（Note:Don't put antennas of jammer towards the base station.Otherwise the block effect will be affected）.

-Step 3:Turn on the power switch.(Noted it must be installed all antennas firstly)

    When the same signal jammer is used outdoors, the interference range will be doubled compared to when it is used indoors. If the interference range 

is within 200m”, generally a jammer can be installed and hung in the middle of the indoor wall, 1~1.8 meters away from the ground; if it is greater than 

200m3 , Generally, two or more sets should be set up and placed on the front and rear walls; if the interference space is outdoors and larger than 1000m, 

multiple sets should be used, and the effect of cellular distribution is better.

    The mobile phone signal jammer, in essence, implements electromagnetic interference on the wireless network on which mobile phone communication 

depends, so that the mobile phone cannot be connected to the Internet, and thus cannot receive information from the mobile network, and cannot send

 information through the network. But it has no effect on the signal generated by the phone.
