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.
Frequency JammerRecently, some old customers have called to ask: I purchased our company's signal blocker many years ago, and the model selected at that time, the standard for blocking mobile phone signals only includes the 2G, 3G or 4G of the mobile phone. With the popularity of 5G mobile phones, in addition to buying the latest 5G signal jammer, is there any way to quickly make the signal of the shielded mobile phone also include 5G without abandoning the original old signal jammer?
I, Nanjing Bokang Electromechanical Technology Co., Ltd. can give a quick solution to upgrade to 5G jammers: customers can continue to use the original old signal jammers to keep the original performance of shielding mobile phone signals. In the 5G signal frequency band, 2-3 SMa-818K90 medium-power 5G jammer modules newly developed and produced by our company can be added directly. This 5G blocker module can be freely spliced and combined, independently powered and used, and can block the frequency band only for 5G in the mobile phone signal.
