Installation and use instructions
4.1 Installation steps and methods
4.1.1 Remove the shield host from the packaging box;
4.1.2 The antennas are rotated into their respective antenna pedestals, otherwise they are invalid.
4.1.3 Put the shield on the wall or the corresponding position, the best installation height is 1-2 meters.
4.1.4 First confirm that the shielder host is full of electricity, and then turn on the power switch. The light on the power supply indicates that the shielder starts to work.
4.2 Notes
4.2.1 The antenna must be installed according to the corresponding identification on the host computer, and then connected to the host power supply.
4.2.2 The effective coverage area of the shield is a circular area centered on the shield. Therefore, when using the shield, attention should be paid to the correct placement of the shield in order to avoid the shielding dead angle.
4.2.3 Shield should be placed in a well ventilated place to avoid large objects and strong electromagnetic source of strong heat source, so as to ensure the shielding effect and long-term stable operation.
4.2.4 When shielding is working, other articles and antennas shall not be stacked or dismantled on the shielding, so as not to affect the shielding effect and damage the machine.
4.2.5 Shield should be cut off in time when it is not in use, so as not to affect the normal use of mobile phones.
4.2.7 Waterproof should be paid attention to when shielding is used outdoors.
4.2.7 When the site area used is larger than the effective shielding range, it is recommended to install multiple Shielders in honeycomb mode to ensure the shielding effect.
4.2.8 Since the power supply and antenna are specially designed for the main engine, and they are one-to-one debugged when they are commissioned out of the factory, please try not to use them interchangeably to ensure good results.
4.2.9 Keep away from corrosive gases and liquids, and do a good job of dust-proof and moisture-proof, in order to avoid accelerating the aging of the internal components of the equipment.
4.2.10 When placed outdoors or in the field, attention should be paid to adding protective devices in the environment where rats, ants and other destructive animals are present.
V. Maintenance
5.1 Bochuang space-time shield is maintenance-free equipment, without maintenance.
5.2 Chemical solvents are forbidden to be used when surface wiping is carried out, and the water in the machine is avoided.
5.3 When the shield is useful, it should be stored in a dry and ventilated place to avoid long-term exposure to salt spray and harmful gases.
5.4 This shield is guaranteed for one year and will be maintained for life.
VI. Question Solution
6.1 When the signal shield is working, why do some cell phone signal indicators still have signal indicators?
A: It's 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 on the signal indicator.
Will the 6.2 signal shield interfere with the normal operation of other electronic devices?
A: No. This is because the electromagnetic signal emitted by the signal shield falls entirely within the prescribed working frequency band of the mobile phone, which will only block the communication of the mobile phone. And this kind of signal is always in a relatively static state, and will not affect any electronic equipment.
6.3 Is the signal shield harmful to human body and mobile phone?
Answer: Please rest assured that the electromagnetic signal intensity emitted by Bochuang space-time signal shield is very weak. It has passed the certification of Guangdong Provincial Health Bureau and microwave radiation detection. The test data show that this signal intensity will not cause harm to 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.
Is there any difference in the operating distance between indoor and outdoor use of 6.4 signal shield?
Answer: Yes. The effective distance of the signal shield (1-40 meters, depending on the distance of different environments) generally refers to the indoor distance. In open outdoor areas, the effective distance of shielding can reach several hundred meters. It should be pointed out that whether 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 shield and so on. Therefore, when using the signal shielder, this factor should be fully taken into account to avoid the shielding dead angle and thus affect the shielding effect.
Does 6.5 signal shield have the same effect on GSM and CDMA mobile phones?
A: That's a good question. Because the anti-jamming performance of the CDMA mobile phone is much better than that of the GSM mobile phone, the effective shielding distance of the signal shielder for the CDMA mobile phone is less than that of the GSM mobile phone, but the difference is not very big, about 2-4 meters. However, it also draws users'attention that in some particularly important places, the number of signal Shielders in the field should be increased when necessary to ensure the shielding effect of CDMA mobile phones.
6.6 After the signal shield works for a period of time, the chassis becomes 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 aluminium alloy drawing case to assist heat dissipation. Thus, it can ensure long-term stable work. Therefore, the hot shell will not damage the machine.
