We sincerely thanks for choosing this jammer for cell phone's signal.
In order to ensure that you can be familiar with the operation of this machine as soon as possible, we provide this end-user's manual in details, which includes introduction of product, method of use, system set, points for attention and variable notices.
TCSPJI and CQST have strictly authenticated this kind of jammer for cell phone signal.
This product can be used in any place that is not allowed for using cell phone.

Rules of installation: UL (E190582) CSA (LR 112971 Level 3)

Taking use of technology of interferencing superhigh frequency.
vIntelligence controlling technology taking charge of the power outputting within the scope of 3 meters.
High effective channel power with rater big semidiameter of interception.
Effectively making subsections, just interferencing downlink and causing no interception of base station.
Imported elements: Slow start up design of circuit can avoid the appearance of sparking when turn on or turn off the machine. Furthermore, these elements can maintain the stable operation condition with high intergration.
Will jammer interference the other electronic equipment to be in good working 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.
 Will jammer have bad effect to human body and cell phone?
You should not 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 no damage will appeared on human body according to the testing files. Mean-while,this device is just damage the receiving condition to cell phone and  makes the normal connection between cell phone and base station impossible. Therefore, no damage will occur on cell phone itself.
 Is there any difference of distance between using jammerindoor and outdoor?
Yes. Generally speaking, outdoor signals is bigger than the indoor signal. Thereby, the shielding effect is worse outdoor. Strictly speaking, whether using indoor or outdoor, the effective distance of interception is related to the surround-ing environment as the distance between different base stations, positions of installation, etc.
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.
 The shell of jammer will become hot after working for some times. Does the long-time keeping in working condition will damage the machine itself?
It is very normal. When design, 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.
