Maybe we all need to know that in many Chinas, there are no laws and regulations on data signal interference devices, but for our applications, we also need to know common issues, including maintenance of key parts, and where can I use them. Among the commonly used mobile phone signal shielding, it is strictly forbidden to use signal shielding to avoid phone harassment, mobile phone ringtones are prohibited, and GPS positioning system shielding protects car whereabouts, prevents tracking, and maintains personal privacy on site.

Based on more than ten years of customer feedback and our experience, here are some key points that should be paid attention to when using signal jammers. Please read carefully.

The interference radius of the signal jammer sold online may be related to the specific location you use it. Sometimes it cannot reach the required range, which may be affected by the surrounding environment. You should use a handy signal blocker, which protects your personal privacy.

Frequently Asked Questions about Portable Jammers:

1. It is strictly forbidden to charge the battery during use. When using, there is no need to charge the battery. When charging, there is no need to use the battery.

2. When the portable jammer is used for a long time, it is strictly prohibited to use it instead of the surface jammer.

Be sure to note:

1. Ensure that wireless antennas and other accessories are installed properly;

2. To ensure sufficient battery capacity, if the handheld display light turns yellow or bright red, it indicates that the switching power supply is out and the shielding effect is not as good as before;

3. The shielding effect depends on the surrounding environment. The interference effect on mobile phones used in suburban areas is better than that in cities. Due to the relatively large density of urban mobile base stations and the close distance between base stations, the urban mobile base subway station causes signals to be transmitted ( The areas that the jammer must block) are several times stronger than those in suburban areas;

4. Ensure that the mobile communication base station is more than 200 meters away:

5. When using a jammer, signals blocked by any metal or wall obstructions must not be transmitted between the antenna, the jammer, and the phone;

6. Magnetic field and strong radio wave environment will affect the application interference effect;

7. The installation height of the shield should be at the same level as the equipment you want to shield.

8. Long-term use of interference will lead to high-calorie food and harm the interference radius;

9. When the phone is on a call, the jammer is not easy to block the data signal (the data signal is very strong during a voice call);

10. The electromagnetic wave emitted by the shield is a high-energy material. It is normal for the high-energy material to accumulate and cause the equipment to become hot;

11. The signal of the mobile phone shows that the update of the grid map is lagging behind. You may have turned on interference but the mobile phone still shows the signal status, but it is actually unavailable on the mobile phone. Please follow the expected results:

12. To test the function of aps jammer, download the GPS signal detection software performance immediately to test the actual shielding effect, or start the car navigation software performance test:

13. WiFi jammer equipment with WIFl interference function will also block other household appliances containing WIFl, such as wireless speakers, speakers, monitors, etc.
