What should I pay attention to when replacing the RF module of the police frequency jammer

The police jammer can selectively open different frequencies according to different usage scenarios. There are also different types of police frequency jammers, such as portable drag box type, vehicle type, backpack type and backpack type. Among them, the portable box-type and vehicle-mounted jammers can quickly replace the modules, but the jammers are not randomly replaced when replacing the RF module. The following points should be paid attention to.

First, before replacing the radio frequency module of the police jammer, be sure to turn off the power first. Although the host device has taken sufficient safety protection measures, when replacing the radio frequency module, please be sure to power off the power first to ensure safe operation and avoid cause personal injury, and also to protect the police frequency jammer.

Second, when replacing the radio frequency module of the police jammer, pay attention to the sequence. First, use a wrench to unscrew the connecting feeder from the radio frequency module, then unscrew the screw fixing the radio frequency module, and then remove the radio frequency module from the host. Pull out. During the pull out process, pay attention to the appropriate force, and then insert the RF module to be replaced into the module compartment, pay attention to the direction of the module, and match the power supply interface of the host module to the power supply interface of the module. Use brute force, then secure the module screws and finally screw on the feeders.

Third, after replacing the radio frequency module, do not rush to supply power to the police frequency signal jammer. First check whether the frequency of the original radio frequency module is the same as that of the replaced module. If the frequencies of the two modules are different, the corresponding antenna needs to be replaced, otherwise It may damage the RF module and antenna, avoid unnecessary losses, and affect the normal use of the jammer.
