Before starting up, ensure that the antenna is connected reliably, and the antenna should correspond to the corresponding identification on the host one by one. It is strictly prohibited to use without connecting the antenna. Recommended installation height for small power: 1.8-2.5m.

 Recommended installation height for high power: 3-10m When the omnidirectional whip antenna configured by the signal jammer is used, the best installation effect is that the antenna is vertical and perpendicular to the ground. It shall be installed in a well ventilated position to avoid large objects blocking the signal jammer, strong heat source and strong electromagnetic source, so as to ensure the shielding effect and stable long-time operation. When working, do not stack other items on it, and do not disassemble the antenna to avoid affecting the shielding effect and damaging the machine. There is certain electromagnetic field interference around the antenna. When not in use, turn off the power supply of the Signal Jammer in time. When using outdoors, pay attention to waterproof or install waterproof protection box. If it is in a relatively sealed space and needs to be turned on for a long time, it is recommended to add ventilation fans and other devices to strengthen heat dissipation, which can strengthen heat dissipation for the equipment host and power lamp respectively. Please keep away from corrosive gases and liquids and do a good job in dust prevention for the signal jammer to avoid aging of internal components of the machine and affecting the service life of the machine. When the use area is large and a single equipment cannot be covered completely, multiple cellular point distribution installation is adopted to achieve the effect of safe coverage When it is placed outdoors or used in the field, in order to prevent the presence of rats, ants, mosquitoes and other destructive animals, protective devices should be added, such as special installation boxes.
