Is your mobile phone always ringing? Is the 4G signal too strong? Let this fixed cellular and WiFi signal blocking device help you quiet down!
The internal module of the device quickly scans and locks the preset frequency band to generate a white noise signal that matches the target frequency band. And it transmits accurately through the antenna, so that the communication device cannot receive the original signal sent by the base station, router or satellite, resulting in interruption or failure of communication, data transmission or navigation positioning functions.
The device shell has been processed with precise stripes, which is beautiful and effectively increases the heat dissipation area, playing a good heat dissipation auxiliary role.
Each antenna adopts a detachable threaded screw interface, which is convenient for users to quickly disassemble and replace, and improves the maintenance efficiency and use flexibility of 4G mobile phone jammers. Each frequency band module operates independently and does not interfere with each other. Even if a single module is abnormal or fails, other frequency bands can still work normally.
Allow users to adjust the power of 8 independent frequency band modules separately according to actual use needs. If the maximum shielding range does not need to be covered, the interference distance can be shortened to prevent excessive spread of signal interference and reduce unnecessary power consumption.
This frequency jammer integrates multiple high-efficiency cooling fans, which quickly discharge the heat inside the body through forced air convection and wind circulation, reduce the core temperature of the device and improve operating efficiency.

T-US-800 long-term maintenance guide:
1. Regularly wipe the device housing with a soft dry cloth to remove dust and stains. Focus on cleaning the heat dissipation holes, use a small hair dryer (low wind speed cold air mode) or dust removal tools to prevent dust from clogging and affecting heat dissipation.
2. Keep at least 20 cm of heat dissipation space around the device, away from high temperature, humidity and confined spaces, to ensure air circulation.
3. Regularly check whether the 8 antennas are firmly connected and not loose, and avoid squeezing, bending or physical damage to the antennas by external forces. If the antenna is found to be damaged, it should be replaced in time with the same specification antenna that matches the original device.
4. Use the original power adapter (12V/10A) for power supply, and regularly check whether the power adapter and power cord are worn, broken or in poor contact. Although the device has anti-reverse connection protection function, it is still necessary to carefully check the positive and negative poles when wiring, and connect correctly according to the instruction manual. When the device is powered on, avoid frequent plugging and unplugging of the power supply to prevent voltage fluctuations from causing hardware damage.
5. When not in use for a long time, place it in a dry and ventilated environment and remove the antenna for proper storage. Use the original packaging box and shockproof materials for reinforcement during transportation to prevent the device from being damaged by strong vibration, collision or extrusion.
