1. The effective coverage range of the shield is the circular area of the shield, so when using it, pay attention to the correct placement of the shield to avoid blind spots in the shielding.

2. The shielder should be placed in a well-ventilated place, try to avoid large objects, and avoid strong electromagnetic sources of strong heat sources to ensure the shielding effect and long-term stable operation.

3. When the shielder is working, no other objects should be placed on top of it to avoid affecting the shielding effect and damaging the machine.

4. When the cell phone jammer is not in use, the power supply should be cut off in time to avoid affecting the normal use of the mobile phone.

5. When using the shield outdoors, pay attention to waterproofing.

6. When the area of the site used is larger than the effective screen range, it is recommended to use multiple jammers to be installed in a honeycomb manner to ensure the screen 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 placing it outdoors or in the wild, you should pay attention to adding protective devices in environments where rats, ants and other destructive animals are infested.


1. The shield 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. The shielder should be stored in a dry and ventilated place to avoid long-term exposure to salt spray and harmful gases.

4. The jammer has a three-year warranty, free replacement within one year, and lifetime maintenance.
