cell phone jammer won't do any damage to the cell phone itself ...
Power IC module Weld or burn? Operating current of the IC, so the probability of failure is high. Power IC with or without boot signal to the CPU? A road load of the power IC with severe leakage or short circuit, causing the power-current, thus protecting the shutdown. CPU, FLASH, the corresponding pin Weld? This is a common fault. CPU, the font can work the three basic conditions: (a) The operating voltage; (b) The size of the clock; (C) whether the CPU and FLASH chip communication data lines are normal and no leakage and so on. Whether the CPU the output poweron signal to the power IC? Initialization software error? Re-write the software to try. Check such failure can be man-made fault isolation. If the blocking range of the single?? cell phone jammer ?? is bigger than the needed shielding range, it can be realized by adjusting the emission power of? cell phone jammer .
That is man-made cross-connected (available for a short fine enameled wire) plus a voltage to the the poweron feet of the power IC, if each of the power IC can output the normal voltage, the point of failure is generally the CPU control section or software, and vice versa point of failure in the power IC part of the boot line or load. Check failure, according to the direction of the signal processing from front to back inspection, may also be forward to check, you can also check from one place in the middle, the specific methods depending on the specific circumstances and mobile phone models. ) Phone does not boot: mobile power supply did not respond to press the power button, the key to check the battery contacts (films) to the power IC and power button (or switch) pathway is normal. The plan for?? cellphone jammer ? system has no special requirements about the architectural layout, floor situation and base station signal strength.
The phone does not boot: mobile phone connected to the power supply, press the power button, the current response (compared to the normal phone too much current), check the phone electric cell circuit short circuit (such as logic or radio frequency), and then check the power supply IC relevant circuit components. phone does not boot: mobile phone connected to the power supply, press the power button, a smaller current response (a few dozen mA or so), such as normal use or charge caused by the failure to check: power supply of each voltage ? Clock ? software ? font-CPU; if dropped or water machine replanting the logical part of the IC, and inspected the components off and disconnected. Phone does not boot: Mobile power supply press the power button is very small current response (a few milliamperes or 10 milliamperes or so), there is no Weld focus on examination of the power supply and 13 trillion and the logic part. This kind of? phone jammer ?? has its own characteristics.
The phone does not boot: mobile phone connected to the power supply has current (leakage current of about 100 to about 500 mA) Check the power amplifier and power supply IC, in the case of the MOTO machine should be checked IF polyphonic cell phone to check the chord chip. Phone does not boot: mobile power supply has short circuit, check the amplifier, chord chip, and power ICs, the charging circuit connected to the circuit with V-the BATT. Phone does not boot 7: mobile power supply is a small current leakage, check the charging circuit and power IC power circuit components. ?The mobile phone then the power will automatically boot; check the power IC, insert the end of the charging circuit and the switch button circuit includes a protection circuit. Needs such as water damp washed and dried and then processed. The special suppression measures have been carried out for the harmonic wave outside the band and? cell phone jammer? will not interfere with other electronic equipments.
Automatically shut down a mobile phone: check the circuit board and battery contacts touch-chip flexible enough so that contact is not good; or circuit board with copper contacts dirty or rusty, to identify the problems with the appropriate cleaning, rust and other approach to solve the problem. The phone turns itself off 2: put the card after boot, the search to the network after the shutdown, hold the card boot will not shut down, such situations generally amplifier circuit and its power lines may be damaged (including the launch of output capacitors, filters and other components). Another: the software is not good also (MOTO type of majority). Phone turns itself off 3: Whether to put the card or cards, as long as a boot, it automatically shut down, which may be software failure, and rewrite information is available to troubleshoot if the machine went overboard, the hardware part of the problem of opportunity is also very big.? cell phone jammers ? has fully considered the detailed situation of mobile communication network in whole machine design and function setting.
