Installation Notes:
- Before installing this device, be sure to install the antenna correctly according to the signs, and then turn on the power to avoid the machine from being burned out. It can be used in small-scale shielding places such as vehicles, offices, etc;
- The device comes with a rechargeable battery, which can be recharged and used for 2 hours at a time. It has a battery protection function inside, constant current and constant voltage charging with overcurrent and overheats protection, charging status indication, and charging current detection. If it has not been used for a long time, please pay attention to the maintenance charge every half month.
Precautions:
- The farther the portable cell phone jammer is from the base station, the farther the shielding distance will be. For example, in GSM, when the signal field strength of the base station at the installation point is -75dBmv, the maximum distance between the shielding center is about 2 meters. The larger the signal field strength of the base station, the smaller the shielding distance. When the signal field strength of the base station is greater than -35dBmv, the maximum distance of the shielding center is only 0.5-1 meters.
- The shielding range refers to the circular area centered on the machine. The shielding signal is sent by the host and spreads outward from strong to weak. Appropriate placement should be selected at the application site, and cellular placement should be adopted to make the shielded signal evenly distributed.
- Human bodies, objects, walls, etc. will block the transmission of shielded signals. When using, try to avoid obstacles.
- The mobile phone jammer should be used in a cool, dry place to avoid direct sunlight and rain and fog invasion
