The importance of installing mobile phone jammer

Demolition and installation of the mobile phone is a basic mobile phone repair, some mobile phone is easy to dismantle and easy to install, such as Ericsson 788, T18 mobile phone.The field strength difference between the indoor space and outdoor space will damage the effect ofmobile phone jammer. But there are many mobile phone, especially some new mobile phones, if the master could not removable tips are very easy to dismantle bad. Observed failure phenomena open the cover after the first circuit board visual inspection. Check whether the cable loose and fracture components whether Weld and break all contacts with or without injury, and corrosion, check, before the power observed, and failure phenomena make a record.
in addition to master its basic principles and means of maintenance, should also pay attention to its maintenance are reasonable steps to carry out maintenance work in an orderly manner.Influence from architectural layout of cell phone jammer in the prison should also be considered.  Repair the phone, follow these steps for maintenance: (1) asks the user to get an awaiting repair mobile phone, the first not to rush to get involved, but to first ask the fault phenomena, time of occurrence, whether manual, the machine usually the work of whether collisions or falls over, is to find someone to repair over and pay attention to observe the appearance of the phone, with or without obvious cracks, defects. If the flip does not, ** folded keyboard bald, can largely determine the fault of the machine, the other to ask the machine is two phone repaired elsewhere not use the number of years about how much.
Touch can touch the level of surface temperature, such as hot, think of whether the current is too large or heavy load can be based on the experience of rough to determine the fault position. (5) thinking and analytical thinking. Previously observed, all the information collected, the use of maintenance experience, combined with a specific principle of the circuit, the use of necessary means of detection, carried out the analysis, thinking, judgment, and finally made the overhaul program. 6. Repair has failed components replacement, welding. The size of the NC box ofmobile phone jammerintelligent system is 47mm×80mm×120mm.
