Generally speaking, many places do not have clear legal regulations on signal interference devices, but for our use, we should also understand the relevant precautions, including the maintenance of equipment performance, and where I can use it. Among our common cell phone jammers, signal jammers prohibit the use of mobile phones, prevent harassing calls, and prevent mobile phones from ringing, while GPS satellite positioning jammers protect the whereabouts of vehicles, prevent tracking, and protect location privacy.

Some things you need to pay attention to when using cell phone jammers in daily life

The interference radius of the signal jammer sold online may be related to the specific location of your use, and sometimes it cannot reach the required range, which may be affected by the surrounding environment. You should use a signal jammer that is easy to carry and blocks interference, it can protect your privacy.

Based on years of customer feedback and our experience, here are some details you should pay attention to when using signal jammers. Please read carefully.

Things to note when using mobile phone signal jammers:

1. Make sure the antenna and other accessories are installed correctly;

2. To ensure sufficient power, the handheld indicator light turns yellow or red to indicate that the power supply has been dropped, and the shielding effect is not as good as usual;

3. Ensure that the mobile base stations are more than 200 meters apart;

4. The shielding effect depends on the surrounding environment. The interference effect of mobile phones used in urban areas is better than that in cities. Because the density of mobile base stations in cities is larger and the distance between base stations is closer, the signals emitted by urban mobile base stations (where the jammer needs to be blocked) are stronger than those in urban areas. multiple times;

5. When using a jammer, there should not be any metal objects or wall obstructions around the antenna and between the jammer and the phone to block signal transmission;

6. Strong magnetic field and strong electromagnetic wave environment will affect the interference effect;

7. The installation height of the jammer should be as high as possible to the same level as the device you want to shield;

8. Long-term use of interference opportunities causes high heat and affects the interference radius;

9. When the phone is on a call, the jammer will not easily block the signal (the signal is very strong during the call);

10. The radio wave emitted by the jammer is a high-energy material. It is normal for the machine to heat up due to the collection of high-energy materials;

11. There is a certain lag in the refresh of the signal display grid on the mobile phone. You may have turned on interference but the mobile phone still shows signal status, but in fact the mobile phone cannot be used. Please refer to the actual results;

12. To test the function of the GPS jammer, please download the GPS signal detection software to test the shielding effect, or open the car navigation function test;

13. The wifi jammer device with WIFI interference function will also block other appliances with WIFI, such as wireless microphones, speakers, monitors, etc.
