Main function of the equipment: This cellular telephone of shielding devices have adopted the special high science and technology way, can make the cellular telephone lose efficiency within the range of assessing from the shielding to cover automatically. The cellular telephone can be used in flammable and explosive place, the specialized quite place, the ordinary quite place extensively, the place where preventing the microwave from interfering, the secret place, the place where forbidding to operate the cellular telephone. This shielding device can make the cellular telephone to receive and send messages the function lose efficiency in the appoint range when it is at working, the cellular telephone is unable to allocate or dial in , thus achieve the goal of forbidding by force. 二..CHARACTERISTIC OF THE EQUIPMENT. With the fast popularization of the cellular telephone, it make people shroud in the radiation magnetic field and the high strength radio frequency. This kind of radio frequency radiation will be caused a threat to the regional security ( such as service station, gas station, the hospital, chemical warehouse, etc) increased day by day . SHIEDLING DEVICE OF CELLULAR TELEPHONE?S CHARACTERISTICS: This equipment is used in general Government, Army, the meeting room of the organ mainly, the confidential room, the secret room, the examination hall and the institution of the school, all enterprises, service station, gas station, hospital, chemical warehouse, the flammable place, the explosive place and specialize quite place, the ordinary quite place, the place where preventing the microwave from interfering, the secret place, the place where forbidding to operate the cellular telephone.
