Precautions about the cell phone jammer
1. The antenna must be installed first according to the corresponding mark on the host, and then the host is powered on (it is strictly prohibited to turn on the power without connecting the antenna).
2. The transmitting antenna of the cell phone jammer adopts a soft whip omnidirectional antenna. The effective coverage range is a gradually weakening area with the antenna as the center of the circle. Therefore, when using it, pay attention to correctly choosing the position and angle of the antenna to avoid blind spots in shielding.
3. The shield should be placed in a well-ventilated place. The antenna should be installed away from large objects, strong heat sources and strong electromagnetic sources to ensure screen effect and long-term stable operation.
4. When the shielder is working, do not stack other items on it or disassemble the antenna, so as not to affect the shielding effect and damage the machine.
5. When the jammer is not in use, the power supply should be cut off in time to avoid affecting the normal use of the mobile phone.
6. When the area of the site used is larger than the effective evaluation range, it is recommended to use multiple shielders to be installed in a honeycomb manner to ensure the best effect.
7. Please stay away from corrosive gases and liquids, and be dustproof and moisture-proof to avoid accelerating the aging of the internal components of the equipment.
8. When installing in the field, attention should be paid to adding protective devices in environments where rats, ants and other destructive animals are infested.
maintenance
1. This signal blocker is a maintenance-free device and requires no maintenance.
2. When wiping the surface, avoid using chemical solvents and avoid water entering the machine.
3. When using the shield, it should be placed in a dry and ventilated place to avoid long-term exposure to salt spray and corrosive harmful gases.
