1. When the signal jammer is working, why do some mobile phone signal indicators still have signal indicators?
Answer: This is just an illusion. In fact, the mobile phone could no longer communicate at this time. When you press the unplug button at will, you will find that there is no signal indication at all on the signal indicator.
2. Will the signal jammer interfere with the normal operation of other electronic equipment?
Answer: No. This is because the electromagnetic signal emitted by the signal jammer completely falls within the nationally prescribed mobile phone operating frequency band and will only block mobile phone communications. And this kind of letter. The signal is always in a relatively static state and will not affect any electronic equipment.
3. Are signal jammers harmful to the human body and mobile phones?
Answer: Please rest assured that the electromagnetic signal emitted by the signal jammer is very weak. Test data shows that this signal strength is far from causing harm to the human body. At the same time, the signal screen. The jammer only blocks the forward signal of the mobile phone so that the mobile phone cannot contact the base station, so it will not cause any damage to the mobile phone itself.
4. Is there any difference in the operating distance of signal jammers when used indoors and outdoors?
Answer: Yes. The effective distance of the signal jammer (10-40 meters) generally refers to the indoor distance. In outdoor open areas, the effective distance of shielding can reach several hundred meters. It should be pointed out that whether in. Whether used indoors or outdoors, the effective distance of the jammer has a certain relationship with the environmental conditions at the time, such as the distance from the base station, the placement location, etc. Therefore, use signal shielding. When installing the device, this factor should be fully considered to avoid shielding dead spots and thus affecting the shielding effect.
5. Does the signal jammer have the same effect on GSM mobile phones and CDMA mobile phones?
Answer: This is a good question. Since the anti-interference performance of CDMA mobile phones is far better than that of GSM mobile phones, the effective shielding distance of the cell phone signal jammer for CDMA is smaller than that of GSM mobile phones. But the difference is not very big, about 2-4 meters. However, users are also reminded that in some particularly important places, the number of signal jammers in the venue should be increased when necessary to ensure the shielding effect on CDMA mobile phones.
6. The case of the signal jammer becomes hot after working for a period of time. Will working for a long time damage the machine?
A: Thank you for your attention. This is a normal phenomenon. In terms of design, we utilize the thermal conductivity of the brushed aluminum alloy casing to assist in heat dissipation. This ensures stable work for a long time.
Therefore, the machine will not be damaged if the casing becomes hot.
