What should be paid attention to when replacing the RF module of the police frequency jammer?
Police jammers can selectively open different frequencies according to different usage scenarios. Police frequency jammers also have different types, including portable tow box type, vehicle-mounted type, backpack type, and backpack type. Among them, portable tow box type and vehicle-mounted signal jammers can quickly replace modules, but when replacing the RF module of the jammer, it is not a random replacement. The following points need to be noted.
First, before replacing the RF module of the police jammer, be sure to remember to turn off the power first. Although the host device has taken sufficient safety protection measures, when replacing the RF module, please be sure to turn off the power first to ensure safe operation, avoid personal injury, and also to protect the police frequency jammer.
Second, when replacing the RF module of the police jammer, pay attention to the order. First, use a wrench to unscrew the connecting feeder from the RF module, then unscrew the screws that fix the RF module, and then pull the RF module out of the host. During the unplugging 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 host module power supply interface with the module power supply interface. Remember not to use brute force before they are matched, then fix the module screws, and finally screw on the feeder.
Third, after the police frequency GPS jammer is replaced with the RF module, do not power the jammer temporarily. First check whether the original module and the replaced module have the same transmission frequency. If the two modules have different frequencies, the corresponding antenna needs to be replaced, otherwise the RF module and antenna may be damaged, avoiding unnecessary losses and affecting the normal use of the jammer.
