In some places where privacy protection or order management are required, limiting the signals of wireless devices such as mobile phones has become a routine operation. This cell phone signal blocking device can effectively block multiple frequency bands such as CDMA, PCS, 3G, 4G, 5G, WiFi and GPS within a range of 5-20 meters. It supports customization of different interference frequency bands according to actual needs to adapt to different usage scenarios.
The actual shielding distance of T-US-B08 will fluctuate according to the on-site environment (such as wall structure, original signal strength, etc.). In small spaces, one device can achieve effective full coverage; for large places, it is recommended to adopt a “cellular” deployment solution with multiple devices staggered.
Installation and use instructions of mobile cell jammer:
1. Screw the antennas into the corresponding antenna interfaces according to the marks and tighten them. The power supply, antenna and host have been matched and debugged before the device leaves the factory. Please do not replace them at will to avoid affecting performance.
2. It is recommended to hang the signal jammer on the wall or place it vertically in the corresponding position. The optimal height is 1-2 meters. Avoid stacking debris on the device or removing the antenna to avoid affecting normal operation and damaging the machine.
3. Plug in the power supply and turn on the switch. The working indicator light on the power supply will light up to indicate that it has started working.
❓ FAQs about desktop jammers
Q1: Why do some mobile phones still display the signal icon when the 5G jammer is working?
A: This is a visual illusion caused by the cache. Although the icon is still there, the mobile phone can no longer make calls or connect to the network normally. It is recommended to try dialing to verify the interference effect.
Q2: Will it interfere with other electronic devices?
A: No. It will only block specific frequency bands. And this signal is always in a relatively static state and will not affect other electronic devices.
Q3: Is it normal for the device casing to heat up? Will long-term work damage the machine?
A: Thank you for your carefulness. This is a normal phenomenon. The device uses the thermal conductivity of the aluminum alloy casing to assist in heat dissipation. Heating after long-term operation is an expected phenomenon and does not affect the service life and safety.
