You must first install the antenna according to the corresponding logo on the host, and then connect the host power. Care should be taken to select the correct shield position and avoid dead corners of the shield because the effective coverage of the shield is the circular area around the shield.

　　The communication suppression device should be installed in a well-ventilated place to avoid blocking by large objects and strong heat sources of strong electromagnetic wave sources, so as to ensure the shielding effect and long-term stable operation. No other items can be stacked while the shield is working. Antennas prevent shielding effects and can damage the machine. When the gps jammer is not in use, please turn off the power, so as not to affect the normal use of the phone. Be careful with water when using the shield outdoors.

　　If the site area is larger than the effective shielding area, it is recommended to use multiple shielding cellular devices to ensure the shielding effect. Due to the power supply, the antenna is dedicated to the host, and the factory trial run is a one-to-one wifi jammer.

　　In the information age, the rapid development of communication technology and mobile phones has become an indispensable tool in people's daily work and life. However, and the widespread use of GPS jamming cell phones, some issues can be largely ignored in production:

　　Avoid using it to ensure the best results. Keep away from corrosive gases and liquids, and keep dust and moisture so as not to accelerate the aging of internal equipment components. When placing outdoor or wild animals, be careful to destroy destructive animals such as mice and ants.

　　Network signal jammers need to shield areas containing cell phones (including GSM, CDMA, DCS, PHS, 3G, 4G) and external interruptions. It can effectively shield the microwave signal between the mobile phone and the mobile phone.

　　Cut off GSM/CDMA/AMPS/DCS/PHS/3G/4G (WCDMA, TD-SCDMA and CDMA2000) mobile radio signal shielding, various types of wireless communication equipment can be adjusted to prevent communication, and can be adjusted according to damage to restore normal use , so the wireless signal equipment required to leave the facility is fixed in a closed area, interfering with the work of other electronic equipment, and the 3G/4G phone jammer has no human body.

　　Smartphone jammers have become a new leak channel, posing a threat to the security of confidential information.

　　With the development of science and technology, the positioning, tracking and monitoring of mobile phones have become the most important reconnaissance and source tools in the world. So as long as you're on standby, whether you're using it or not, as long as you keep your phone in a secret place, radio wave blocking devices are caused by leaking into the country most likely to cause serious harm to units, individuals and organizations in this way.
