Product introduction
Bcsk-mini (single) is a compact and portable GPS signal shield, which is specially designed for vehicle GPS navigation, positioning and speed measurement equipment,
Depending on the power supply of the vehicle cigarette lighter, the product can automatically start transmitting GPS interference signals as the vehicle starts,
Thus, the on-board navigation equipment completely loses the functions of positioning, navigation and speed measurement, and can perfectly prevent the leakage of position information.
Bcsk-mini (single) GPS shield of Bochuang space-time brand is equipped with a group of signal generators and a high gain omnidirectional antenna,
After startup, it can continuously transmit Gaussian white noise for GPS signal to the surrounding 360 degree circular range, so as to cut off the data communication between on-board GPS equipment and GPS satellite,
Make the on-board GPS device inoperative. The actual shielding range can reach 20m, which can fully meet the shielding requirements of civil vehicles.
The equipment is equipped with a skillfully designed safety circuit. The fuselage is a three-stage design, light and portable, with low failure rate,
It can work stably and continuously for a long time. In all kinds of high and low temperature environments, the service life of the product is more than 3 times higher than the average level in the industry.

Basic knowledge of shielding instrument installation and operation instructions
1. Take out the host of Bochuang spatiotemporal brand jammer from the packaging box;
2 screw the antennas into their corresponding antenna bases respectively, otherwise they are invalid;
3. Hang the shielding instrument on the wall or at the corresponding position, and the recommended installation height is 1-2m;
4 turn on the power switch, and the work indicator on the power is on, indicating that it starts to work. If it is the style of built-in lithium battery, please check that it is fully charged before use.
matters needing attention
1. Please install the antenna according to the corresponding identification on the host, and then turn on the host.
2. The specific coverage of the shielding instrument is a circular area centered on the shielding instrument, so pay attention to correctly select the placement position of the shielding instrument during use 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 shielding instrument shall be placed in a well ventilated place, avoiding the shielding of large objects and the strong electric and magnetic source of strong heat source as far as possible, so as to make the shielding effect and stable operation for a long time.
4. When the shielding instrument is working, other articles shall not be stacked on it and the antenna shall not be disassembled, so as not to affect the shielding effect and damage the machine.
5. When Bochuang spatiotemporal brand jammer is not in use, the power supply shall be cut off in time to avoid affecting the normal use of mobile phones.
6. Pay attention to dust and water when using shielded instruments outdoors. Please keep away from corrosive gases and liquids, and do a good job in dust and moisture, so as not to accelerate the aging of other components of the equipment
7. When the used site area is larger than the actual shielding range, it is recommended to use multiple shielding instruments for honeycomb installation to confirm the shielding effect.
8. Since the power supply and antenna are used together with the host and are debugged one by one during factory debugging, please try not to use them interchangeably to achieve good results
9. The warranty period of Bochuang space-time shielding instrument is one year, providing long-term technical consultation and maintenance.
Problem solving
1. When the signal shielding instrument works, why do some mobile phone signal indications still have signal indications?
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 shielding instrument interfere with the normal operation of other electronic equipment?
A: No. This is because the electromagnetic signal sent by the signal shielding instrument 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 in a relatively static state and will not affect other electronic devices.
3. Is Bochuang spatiotemporal brand jammer harmful to human body and mobile phone?
A: please rest assured that the electromagnetic signal intensity emitted by the signal shielding instrument is very weak. The test data show that this signal intensity will not cause harm to people. Meanwhile, Bochuang spatiotemporal signal shielding instrument only blocks the forward signal of the mobile phone, so that the mobile phone can not contact the base station, so it will not damage the mobile phone itself at all.
4. Is there any difference in the action distance between indoor and outdoor signal shielding instruments?
A: Yes. The actual distance of signal shielding instrument (5-40m) generally refers to the indoor distance. In the outdoor open area, the actual distance of shielding can reach tens of meters. It should be pointed out that whether it is used indoors or outdoors, the effective working distance of the shielding instrument is related to the environmental conditions at that time, such as the distance from the base station, the location, etc. Therefore, this factor should be considered when using signal shielding instruments to avoid shielding dead angle and affect the shielding effect.
5. Does Bochuang spatiotemporal brand jammer 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 Bochuang space-time signal shielding instrument 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, the number of signal shielding instruments in the field should be increased when necessary to improve the shielding effect of CDMA mobile phones.
6. The casing of Bochuang spatiotemporal brand jammer is hot after working for a period of time. Will it damage the machine after working 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. Thus, it can work stably for a long time. Therefore, the hot casing will not damage the machine.
