Product Description Taking use of super-high frequency and mini-power interference technology, high efficiency Effectively making subsections, just interfering downlink and no interception on the base station Extreme portability, the weight for machine itself and antenna are just 0.35KG Slow start up design of circuit. These elements can maintain the stable operation condition with high integration. Connection:Four SMA connectors which are used to connect with antenna (CDMA GSM/DCS PHS GPS/WIFI) Compact size - easily fits in your bag or purse Built in rechargeable li-ion battery Can be charged by AC adapter or car charger Warning : Do not to use this Jammer for any illegal purpose, otherwise you may be subject to prosecutions under applicable laws. You should be aware that we are obliged to provide the information in connection with your purchase of this product to relevant administrative and judicial authorities at their request. Notes Do not place the device directed to the sunlight or near the high temperature fires While it is working, the surface temperature is about 45 centigrade. It is normal. However, if it is higher than 45 centigrade, it is abnormal. Please put the power SW to OFF immediately and try to contact your local distributor or agent The shielding range of the device will be determined by the local signal strength . In different situation, it will be with different performance. Please try to put the device in a higher position while it is working .It will be better. The suggested height is about 2M. To avoid the loss of function of the device, please try to avoid the device placed on or the metal materials. Do not put the device near computers, notebook computers, televisions, stereos, and radios and so on , in order not to make some interference for these equipments. Do not turn on the power before the antennas is installed If the antenna is not properly installed in accordance with the manuals, the shielding range will be not so good. make sure the correct installation before turn on the power. If the charged times is more than 500 times and then cannot be charged any more, please contact your local dealer or dealer and replace the battery.
