detector of cell phone jammer intelligent system and software

Do not fail ** smuggling chips, components, to avoid the more complex failure. In this, the correct analysis of the circuit, correct an error of judgment. The right to find fault position is very important to avoid false positives. Note Check your phone’s menu settings are correct, a lot of phone failure was caused because the menu is not set in the correct state. 10 The service is completed, cleaning, sorting table is necessary. Homing repair tools, all the attachments (long screws, ** sets, rubber, insulator, etc.) re? ***. Hope? And then restart the detector ofcell phone jammerintelligent system and software.Lok cut Tuan, Xi Huai tangled, bad stunned? Ao? Lt ;/ p> maintenance personnel to master the basic terminology and basic knowledge of mobile phone repair in order to determine the failure to produce the original back and the approximate range, to avoid one by one according to its principles of testing, or to find the point of failure in the entire circuit board. Troubleshooting steps phones regardless of what type of failure, must be asked, see, hear, touch, thought to repair the six stages. Just for different models, different faults, maintenance for the six stages at different times.
Should use the soldering iron under the IC with the warmth of iron welding, Heat, unplug the iron, and then welding. Before servicing attention to the matter of mobile phone before servicing, you should note that the following matters: Connect RXDOUT（A）socket of the second detector ofcell phone jammerintelligent system with the RXDIN(B) socket of the third detector ofcell phone jammerintelligent system through the net line.1. Cell phone integrated circuits, microelectronic products, integrated circuits, precision through advanced technology research and development from maintenance personnel must understand each chip logical link, the performance of the components to understand the circuit, circuit analysis, carefully check the correct judgment, fast and accurate operation,
Mainly, first, the water moisture, so that the components subject to corrosion, insulation level drop, the control circuit is out of control, resulting in a logic system disorders, the software program is not working properly, a direct result of the phone does not boot.One end of 232-485 commutator connects with the serial port of the computer and the other end connects with RXDIN（B）socket (fastening) of the first detector ofcell phone jammerintelligent system through the net line.
