The portable frequency jammer can selectively turn on different frequencies according to different use scenarios. Portable jammers can also be divided into trailer type, vehicle type and backpack type according to different types of equipment. Among them, the radio frequency module of the portable jammer of the trailer type and the vehicle type can be quickly replaced. When replacing the RF module of the portable jammer, pay attention to the following points.

First, before replacing or disassembling the RF module of the portable frequency jammer, the host of the portable frequency jammer must be powered off. Although the host equipment has already taken sufficient safety protection measures, when replacing the RF module, please power off first to ensure safe operation and avoid personal injury, and also to protect the portable jammer.

Second, the portable frequency jammer should pay attention to the sequence when disassembling and replacing the RF module. First, remove the connecting feeder of the RF module with a wrench, then remove the fixing screws of the RF module, and then pull the RF module out of the host. During the pulling out process, grasp the handles at both ends of the RF module, and use both hands evenly to remove the RF module. Then, insert the RF module to be replaced into the module bin, pay attention to the direction of the module, Moreover, the power supply interface of the host module shall be corresponding to the power supply interface of the module. Before it is not corresponding, remember not to use brute force, then fix the module screws, and finally screw on the feeder.

Third, after replacing the RF module, the portable jammer should not worry about power supply. First, check whether the frequency of the original RF module is the same as that of the replaced module. If the frequency of the two modules is different, the corresponding antenna needs to be replaced. Otherwise, the RF module and the antenna may be damaged to avoid unnecessary loss and affect the normal use of the portable jammer.
