The main computer can show the situation of cell phone jammer system

Part Examination of cell phone jammer
The third measure: the jaws - tyranny without transmitter failure: dial "112", measuring transmitter a voltage of about 2V contacts have. There voltage: the majority of the transmitter failure or bad, can adjust the contacts clean, replace the transmitter. No voltage: fault mostly audio between the transmitter IC to break or damage the audio IC. You can pull all the way to the first voltage of 2V to try to send it's positive, it can also solve part of the fault. Some phones have a special responsibility headcell phoneswitch control tube, this tube also easily soldered or damage caused by free to send it. The installation and height can influence the blocking range of cell phone blocker .
Transmitter noise filter capacitor failure is mostly caused by deterioration, deterioration of the capacitor can be replaced. Can also be polarized between the transmitter plus a way to improve capacity. Example: Samsung N288 mobile cell phoneone, no mouthpiece, plus welding the top of the two sent by the CPU, then switch troubleshooting (such as the line can still short the two separately controlled tube 5 #, 6 # foot). Example: V998 cell phoneone set, get it from time to time, the player check the transmitter good contact, plus welding audio (set in power within the IC), the troubleshooting. Example: Samsung X199 mobile cell phoneto send it a great noise, replace the transmitter and the transmitter of a capacitor connected in parallel between the positive and negative after troubleshooting. The security is installing cell phone jammer  in the hall.
Tip: Often used in the article talked about how to change the hands-free solution, then sent by the failure, is a very practical technology. This is not only suitable for beginners or trained maintenance staff to learn, for skilled workers, at the appropriate time, I will put my friends in a "human resource configurations" for everyone to Dramas. Martial arts to keep fit, brothers, colleagues, I hope you have received. The fourth move, eyes - tyranny display fault: display a variety of performance failure: an out-line - is usually caused by damage to the display, must be replaced. When the time was not significant, down-screen, the video - on a cable, usually should be checked, replace the cable; for cable-less, and generally conductive adhesive caused by aging or display interface Weld. The main computer can show the situation of cell phone jammer system.
Screen displays a black screen or short - mostly on the resistor-capacitor circuit shown deterioration caused deterioration can replace the capacitor, resistor to change the contrast adjustment to improve the solution. No show - can replace the method to determine whether the fault in the motherboard, by analyzing the causes of failure can basically determine the point of failure, our data can be shown by measuring the voltage is normal to judge. Example: One station Ericsson T28 mobile phone, display time to time, when the concentrated light when, after the replacement of conductive adhesive and display invalid test shows voltage, the voltage is sometimes found in the display is only 5.8V 4V or so, check that C607 leakage, replacement of C607 troubleshooting. Example: Motorola V8088 one, and sometimes no display, sometimes down screen, the video phenomenon, replacing a PCB cable and cut as usual. The LED screen will show the running state of cell phone jammer system.
Example: TCL6898 a cell phone, no display, ask the customer to know, out of date a few days ago there were not significant when the situation was entirely without display was to determine the cable failure, replacement OK. Example: a Nokia 8250 no display, the measured voltage of the normal display, replace the conductive adhesive troubleshooting. Example: CECTQ200 a cell phone, 3 seconds after power is no big-screen display, a careful analysis of observations, also found that failure of a key at this time, if the flip is closed when the response to the control flip key clean-up after everything is normal. Example: TCL668 color cell phonewithout a display, replace the entire display is invalid, re-planting the CPU OK. The cell phone jammer system can automatically alarms if the  cell phone jammer system works abnormally.
