    Question and answers
    1. The shell of jammer will become hot after working for some times. Does the long working time will damage the machine itself?

    It is very normal. When designing, we are thinking of taking use of the conductivity of metal shell to help the heat sinking during our designation. By this way, the machine can be kept in good working condition for long time.

    2. Is the jammer has the same effect to GSM cell phone and CDMA cell phone?

    The capacity of anti-interference of CDMA is much better than GSM cell phone. So the interference effect for GSM cell phone is better than CDMA cell phone.

    3. Is there any difference of distance between using jammer indoor and outdoor?

    Yes. Generally speaking, outdoor signal is bigger than the indoor signal. Thereby, the shielding effect is worse outdoor. Strictly speaking, whether using indoor or outdoor, the effective distance of interference is related to the surrounding around, for example the distance between different base stations, positions of installation etc.

    4. Does jammer interfere the other electronic equipment to work in normal condition?
    No. Because the electromagnetic signal sent by jammer are totally used in the band that regulated by government and just have interception effect to cell phone communication.

    5. Is jammer harmful to the human body and cell phone?

    Please do not need to worry about it. The intensity of electromagnetic signal sent by jammer is in compliance with the national standard of environmental electromagnetic wave health. The signal sent by jammer is relatively small and unharmful to human body according to the testing result. Meanwhile, this device just damage the receiving condition to the cell phone and makes the normal connection between cell phone and base station impossible. Therefore, no damage will occur on cell phone itself.

    Prisons, Military, School, detention house or Government buildings, and other sensitive locations where the mobile phone signals are not allowed.
