Important Notes for Jamming Distance: The jamming distances we mentioned on website are for customer's reference only. The actual jamming distance will be varied depending on the signal strength and the use location and if full charges, etc.
Important Notes for Portable Jammers with No Cooling Fan: Do not use the jammer when it is charging, or it will burn the jammer as it has no built-in fan. If because of this factor due to the broken of the jammer, the customer will lose the authority of free repairation .

Basic knowledge of shielding
Installation and usage instructions
1. Take out the host of Bochuang space-time brand mobile signal blocker from the packing box;
2 screw the antenna into their respective antenna base, otherwise invalid;
3. Put the shield on the wall or the corresponding position, the best installation height is 1-2 meters;
4 Turn on the power switch, and the work indicator light on the power will start to work. If it is the model with built-in lithium battery, please ensure that it has been fully charged before use.
Matters needing attention
1 Install the antenna according to the corresponding identifier on the host before powering on the host.
2. The effective coverage range of the shield is the circular area centered on the shield, so pay attention to the correct placement of the shield to avoid the blind Angle of the shield; If it is a directional antenna, the target can be adjusted according to the standard fan Angle of the antenna.
3. The shield should be placed in a well-ventilated place, and try to avoid the occlusion of large objects and the strong electromagnetic source of strong heat source to ensure the shielding effect and stable work for a long time.
4 when the shield is working, do not stack other items on it and remove the antenna, so as not to affect the shielding effect and damage the machine.
5 When the shield is not in use, the power should be cut off in time to avoid affecting the normal use of the mobile phone.
6 When the shielding device is used outdoors, it should be dustproof and waterproof. Keep away from corrosive gases and liquids, and ensure that the device is dustproof and moisture-proof to prevent aging of components
7 When the site area is larger than the effective shielding range, it is recommended to install multiple shields in cellular mode to ensure the shielding effect.
8. As the power supply and antenna are specially matched with the host, and the factory debugging is one by one, please try not to use them interchangeably to ensure the best effect.
The shield is guaranteed for one year and lifetime maintenance.
Problem solving
1 Bo chuang space-time brand signal shielding device when working, why some mobile phone signal indication still have signal indication?
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 the signal indicator has no signal indication.
Will the signal shield interfere with the normal operation of other electronic equipment?
A: No. This is because, the electromagnetic signal that signal shield sends out falls in the mobile phone working band that the country sets completely, can produce to the mobile phone communication block effect only. And this signal is always in a relatively static state, will not affect any electronic equipment.
3 Is the signal blocker harmful to human body and mobile phone?
Answer: please rest assured that the intensity of the electromagnetic signal emitted by the signal shield is very weak. The test data show that the intensity of the signal is far from harmful to the human body. At the same time, the signal blocker only blocks the phone's forward signal, preventing the phone from communicating with the base station, so there is no damage to the phone itself.
Is there any difference between the operating distance of the signal shield when it is used indoors and outdoors?
A: there are. The effective distance of the signal shield (10-40 meters) generally refers to the indoor distance. In open areas outside, the effective distance of the shield can be several hundred meters. It should be pointed out that whether it is used indoors or outdoors, the effective action 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, etc. Therefore, this factor should be fully considered when using the signal shielding device to avoid the blind Angle of shielding which will affect the shielding effect.
Does bochuang space-time signal blocker have the same effect on GSM mobile phone and CDMA mobile phone?
A: That's a good question. Because the anti-interference performance of CDMA mobile phone is much better than GSM mobile phone, therefore, the effective shielding distance of signal blocker for CDMA mobile phone is less than GSM mobile phone, but the difference is not very big, about 2-4 meters. But also draws the user attention in some particularly important place, if necessary should increase the number of signal shielding device in the field, in order to ensure the shielding effect of CDMA mobile phone.
6. The housing of the signal shield gets hot after working for a period of time. Will it damage the machine if working for a long time?
A: Thank you for your care. This is a normal phenomenon. Design, we are using aluminum alloy wire drawing housing thermal conductivity to assist heat dissipation. Thus can guarantee long time stable work. Therefore, hot housing will not damage the machine.
