If there are 4 or more anti-theft security EAS system installed on site, working online, all the devices are not working (RF)? Three method,one is to detect the power indicator and detect the output of each power supply, especially the main transmit power. The second method is to use EAS to detect the main transmitting antenna to see if the transmitting frequency is normal, including the center frequency, modulation frequency, sweep width and so on. Three is if the main transmitting board is broken, replace it with the standby board directly; if there is no spare board, the main and sub-transmitting board mode can be replaced (that is, the main jump is paired, the secondary jumps into the main), and the online line is adjusted. Or directly adjust the transmitter board and the receiver board, and the debugging can be normal.
