Signal jammer question you want to ask: 

Q1, When the signal blocker is working, why do some mobile phone signal indications still have signal indications?

A: It's just an illusion. In fact, at this time the mobile phone has been unable to communicate.

When you randomly press the pull button, you will find that there is no signal indication on the signal indicator.

Q2, Will the signal blocker interfere with the normal operation of other electronic equipment?

A: No. This is because the electromagnetic signal sent by the signal blocker completely falls within the working band of the

mobile phone stipulated by the state, which will only have a blocking effect on mobile phone communication.

And this signal is always in a relatively static state, will not affect any electronic equipment.

Q3, Is the signal blocker harmful to the human body and the mobile phone?

A: Please rest assured that the electromagnetic signal emitted by the signal blocker is very weak, and the test data show that this signal

strength is far from harmful to the human body. At the same time, the signal blocker only blocks the forward signal of the phone,

so that the phone can not contact the base station, so it will not cause any damage to the phone itself.         

Q4, Is there a difference in the working distance between the signal blocker used indoors and outdoors?

A: Yes. The effective distance of the signal blocker (10-40 meters) generally refers to the indoor distance. In the outdoor open area,

the effective distance of the shield can reach several hundred meters. It should be pointed out that whether it is used indoors or outdoors,

the effective distance of the shield has a certain relationship with the environmental conditions at that time, such as the distance from the base station,

the location of the installation. Therefore, when using a signal blocker, this factor should be fully taken into account to avoid shielding dead corners that affect the shielding effect.

Q5, Does the signal blocker work the same for GSM mobile phones and CDMA mobile phones?

A: That's a good question. Because the anti-interference performance of CDMA mobile phones is far better than that

of GSM mobile phones, the effective shielding distance of signal blockers for CDMA mobile phones is smaller than that of GSM mobile phones,

but the difference is not very big, about 2-4 meters. However, it is also reminded that in some particularly important places, the number of signal

blockers in the field should be increased when necessary to ensure the shielding effect of CDMA mobile phones.

Q6, After the signal jammer works for a period of time, the shell will be hot, will it damage the machine if it works for a long time?

A: Thank you for your care, this is a normal phenomenon. In design, we use the thermal conductivity of the aluminum

alloy wire drawing shell to assist in heat dissipation. Thus, it can ensure long-term stable work.

Therefore, hot casing will not damage the machine.
