matters needing attention
1. The antenna must be installed according to the corresponding marks on the host, and then connect the host power of Bochuang space-time shield.
2. The effective coverage of Bochuang spatiotemporal brand shield is a circular area centered on the shield, so pay attention to correctly select the placement position of the shield to avoid shielding dead angle; If it is a directional antenna, the alignment direction can be adjusted according to the standard sector angle of the antenna.
3. The shield shall be placed in a well ventilated place to avoid the shielding of large objects and strong electric and magnetic sources of strong heat sources, so as to ensure the shielding effect and stable operation for a long time.
4 when the shield works, it is not allowed to stack other articles and disassemble the antenna on it, so as not to affect the shielding effect and damage the machine.
5. When Bochuang spatiotemporal brand shield is not in use, the power supply shall be cut off in time to avoid affecting the normal use of mobile phones.
6. When using the shield outdoors, pay attention to dust prevention and waterproof. Please keep away from corrosive gases and liquids, and do a good job in dust and moisture prevention, so as not to accelerate the aging of internal components of the equipment
7. When the used site area is larger than the effective shielding range, it is recommended to use multiple shields for honeycomb installation to ensure the shielding effect.
8. Since the power supply and antenna are specially matched with the host and are debugged one by one during factory debugging, please try not to use them interchangeably to ensure the best effect..
9. The shield has a warranty period of one year and lifelong maintenance.
1. Why is there still signal indication on some mobile phones when the signal shield of Bochuang spatiotemporal brand works?
A: This is just an illusion. In fact, at this time, the mobile phone has been unable to communicate. When you press the pull-out button at will, you will find that there is no signal indication on the signal indicator.
2. Will the signal shield interfere with the normal operation of other electronic equipment?
A: No. This is because the electromagnetic signal sent by the signal shield completely falls within the working frequency band of the mobile phone specified by the state, which will only block the mobile phone communication. And this signal is always in a relatively static state and will not affect any electronic equipment.
3. Is the signal shield harmful to human body and mobile phone?
A: please rest assured that the electromagnetic signal intensity emitted by the signal shield is very weak. The test data show that this signal intensity will not cause harm to the human body. At the same time, the signal shield only blocks the forward signal of the mobile phone, so that the mobile phone can not contact the base station, so it will not cause any damage to the mobile phone itself.
4. Is there any difference in the action distance of Bochuang spatiotemporal brand signal shield when used indoors and outdoors?
A: Yes. The effective distance (10-40m) of signal shield generally refers to the indoor distance. In outdoor open areas, the effective distance of shielding can reach hundreds of meters. It should be noted that whether used indoors or outdoors, the effective working distance of the shield is related to the environmental conditions at that time, such as the distance from the base station, the location, etc. Therefore, when using the signal shield, this factor should be fully considered to avoid shielding dead angle, which will affect the shielding effect.
5. Does the signal shield of Bochuang spatiotemporal brand have the same effect on GSM mobile phones and CDMA mobile phones?
A: that's a good question. Because the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the effective shielding distance of signal shield for CDMA mobile phones is less than that of GSM mobile phones, but the difference is not very large, about 2-4m. However, users are also reminded that in some particularly important places, if necessary, the number of signal shields in the field should be increased to ensure the shielding effect of CDMA mobile phones.
6. After the signal shield of Bochuang spatiotemporal brand works for a period of time, the casing is 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 aluminum alloy wire drawing casing to assist heat dissipation. So as to ensure long-term stable operation. Therefore, the hot casing will not damage the machine.
