Borch Space-Time 2018 new BCSK-NZ880 full-band mobile phone shielding machine, shielding all mobile Unicom Telecom three network operators in the market 2G, 3G, 4G mobile phones + WIFI wireless Bluetooth, wireless network transmission, BCSK-NZ880 mobile phone shielding machine is our company Adopting advanced foreign technology, imported components, and carefully developed high-tech products according to the actual situation of domestic mobile communications. This model has been sold in the international market for many years. It is now recommended to school examination rooms, prisons, detention centers, military regions, military units, churches, and confidentiality. In conference rooms, factories, and other places, the antenna power supply is built-in and does not need to be installed. It saves the trouble of installing other antennas corresponding to the antenna. It can work by plugging in the power directly. When using it, it is better to place it vertically.

Fourth, installation and use instructions
4.1 Installation steps and methods
4.1.1 Remove the shield host from the box;
4.1.2 Rotate the antennas into their respective antenna mounts, otherwise it is invalid;
4.1.3 Hang the shield on the wall or corresponding position, the best installation height is 1-2 meters;
4.1.4 Make sure that the main unit of the shield is fully charged, and then turn on the power switch.
4.2.1 The antenna must be installed according to the corresponding identification on the host, and then power on the host.
4.2.2 The effective coverage of the shield is a circular area centered on the shield. Therefore, pay attention to the correct selection of the placement of the shield during use to avoid shielding dead corners.
4.2.3 The shield should be placed in a well-ventilated place. Avoid large objects as much as possible and strong electromagnetic sources with strong heat sources to ensure shielding effect and long-term stable operation.
4.2.4 When the shield is working, it is not allowed to stack other objects on it and disassemble the antenna, so as not to affect the shielding effect and damage the machine.
4.2.5 When the shield is not in use, the power shall be cut off in time to avoid affecting the normal use of the mobile phone.
4.2.7 When using the shield outdoors, pay attention to waterproof.
4.2.7 When the area of the used area is larger than the effective shielding range, it is recommended to use multiple shields for honeycomb installation to ensure the shielding effect.
4.2.8 As the power supply and antenna are used exclusively with the host, and they are debugged one-to-one during factory debugging, please try not to use them interchangeably to ensure good results.
4.2.9 Please keep away from corrosive gases and liquids, and do dustproof and moistureproof work, so as not to accelerate the aging of the internal components of the equipment.
4.2.10 When placed outdoors or in the wild, attention should be paid to the installation of protective devices in the environment of destructive animals such as rats and ants.
5.1 Borch space-time shield is maintenance-free equipment and requires no maintenance.
5.2 When cleaning the surface, do not use chemical solvents and avoid water in the machine.
5.3 When the shield is useful, it should be stored in a dry and ventilated place to avoid prolonged contact with salt spray and harmful gases.
5.4 Borch Space-Time Shielding Device has a warranty period of one year and lifetime maintenance.
Questions and Answers
6.1 Why do some mobile phone signal indications still indicate when the shield is working?
Answer: This is just an illusion. In fact, the mobile phone could not communicate at this time. When you press the pull button at will, you will find that there is no signal indication on the signal indicator.
6.2 Does the shield interfere with the normal operation of other electronic equipment?
Answer: No. This is because the electromagnetic signal emitted by the shield completely falls within the specified mobile phone operating frequency band, and will only have a blocking effect on the mobile phone communication. And this signal is always in a relatively static state, which will not affect any electronic equipment.
6.3 Is the shield harmful to humans and mobile phones?
A: Please rest assured that the strength of the electromagnetic signal emitted by Borch Space-Time Shield is very weak, and it has been certified by the Guangdong Provincial Health Bureau for microwave radiation testing. The test data shows that this signal strength is far from harmful to the human body. At the same time, the shield just blocks the forward signal of the mobile phone, making the mobile phone unable to contact the base station, so it will not cause any damage to the mobile phone itself.
6.4 Is there a difference in the working distance of the shield when it is used indoors and outdoors?
Answer: Yes. The effective distance of the shield (1-40 meters, not necessarily according to the environment) 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 it is used indoors or outdoors, the effective working distance of the shield has a certain relationship with the environmental conditions at the time, such as the distance from the base station and the location of the base station. Therefore, when using a shield, this factor should be fully considered to avoid shielding dead corners and affect the shielding effect.
6.5 Does the shield have the same effect on GSM and CDMA phones?
A: That's a good question. Because the anti-interference performance of CDMA mobile phones is far superior to GSM mobile phones, the effective shielding distance of the shield for CDMA mobile phones is smaller than that of GSM mobile phones, but the difference is not very large, about 2-4 meters. However, users are also reminded that in some particularly important places, the number of shields in the field should be increased if necessary to ensure the shielding effect on CDMA mobile phones.
6.6 After the shield works for a period of time, the cabinet will be hot. Will it damage the machine for a long time?
A: Thank you for your attention, this is a normal phenomenon. In design, we use the thermal conductivity of the aluminum alloy wire drawing case to assist heat dissipation. This can ensure stable operation for a long time. Therefore, a hot case will not damage the machine.
