Important Notice About mobile phone jammers


Notes about the jamming range:


In our specifications and product data sheets we specify the maximum jamming range in the description of our jammers, but the range depends on the signal strength in the area, the location of the antennas, the battery charge (if it has a built in battery) and other typical circumstances of the telecommunication systems. Please pay special attention to the shadow effect and Faraday cage effect, which are circumstances that tend to interfere with communication systems.


Important notices about portable jammers without a fan or a heavy duty cooling system:


In jammers without fans or own cooling systems, avoid continued use or try to not use them when charging the battery to avoid overheating and overloading. Warranty of this product will be void and non-binding if the damage of the product is a result of owner misuse.



1) The jamming range of the device will be determined by the strength of the telephony signal in the area where the jammer is used. So in different situations will have different performance.

2) Please try to put the device in a position as high as possible and with antennas up for better performance. The suggested height is about 2m is 1.5m. To prevent loss of device function, please try to avoid placing the device on or near metal objects or structures.

3) Do not place the device near computers, laptops, televisions, stereos, radios, etc. These devices may be interfered by the signal saturation zone that occurs around the jammer, interfering with the function of the devices.

4) Read the attached manual carefully.
