The portable cell phone jammer has powerful interference capabilities with 3 watt output power. At the same time, it has small and lightweight features which is convenient anywhere used. It can jamming the CDMA GSM and 3G cellular network signals. Besides, it also provides other interference signal, such as the common signal of GPS, WIFI and 315MHz, 433MHz, 868MHz remote control frequencies. Here are a variety of signal interference combinations for you. All the shielding combinations maximum interference radius can reach 15 meters.

Packing List:

1 * Handheld black signal jammer
1 * AC charger
1 * Car charger
4 * Antennas

Note:
1) : Connecting all the antennae before the power supply switched on;
2) : When you get the device in the first time,recharge the device only after the power is used out,and try to recharge it no less than 12 Hours;
3) : Any sealed mark on the machine teared are void;
4) : Don't put the jammer in the water and fire, avoid using in the bad, Condition of over-wet, over-hot, high voltage and high magnetism;
5) : Antennae should be used vertical to the ground, working more efficiently.
