Cell phone jammer has the dynamic jamming range

Not synchronized, the receiver is a "processing line", a process problem will not get finished. N8310 problems "process" no local oscillator signal for demodulation. LO no wave, no power supply to it, to lazy to avoid the risk, to avoid demolition of the power IC, by electricity, are still not synchronized. Check letter machine synchronization is still starting from the power supply, the results identified the RF reference voltage on the 2nd, not sent to the IF IC, into the water corrosion, fly line to solve. Why know the two points of the fly line? Have long measured the light board, draw the "aviation map" Third, do not call "signal diving" is a do not call this broad category.    cell phone jammer can block the cell phone band or GPS band simultaneously.
Previous articles have mentioned that the APC unit of the transmitter drag things, if the baseband unit of the transmitter can the TXIQ signals, visual baseband unit you're done. Inspection focused on APC this period of "assembly line" VAPC low drive voltage of the amplifier current size, the voltage generated in the mobile phone repair "in October 2004, the journal block diagram, this figure is a" common parts ", applied in N8310 phone , the power control IC are arranged within the IF IC, the basic principle is that the two inputs to compare, change the output control amplifier. Since the power supply are normal, not a good dry, it can only run the "who is out, who not, who laid off" the principle, the result is obvious, IF IC quit after the change.    cell phone jammers is very easy for you to carry around.
Judge the "Whose" is the hardest on the aviation map is the direction of the arrow, the arrow represents the current direction of the power supply line, the signal line direction of the arrow represents the signal flow of the arrow of the Line of Control on behalf of who controls who , which requires a certain "skill". But there are some original arrow diagram labeled puzzling! Electronics, computers, communications infrastructure almost maintenance staff do not have to worry about, good use of aeronautical charts and tireless efforts perhaps "Qingchuyulan, rather than blue. Automatically shut down the phone, also known as automatic power-off, is divided into irregular shutdown button to shut down, calls shutdown boot after shut down, unable to maintain the boot close the clamshell shut down and launch the shutdown seven kinds. This mini GPS    phone jammer can fit into the palm of your hand.
These failures are more annoying and difficult to rule out failure, repair is often impossible to start with, and even some experience in the maintenance master "confusion maintenance to observe, seize the nature of the fault, repair this failure does not difficult. The following were analyzed. From time to time automatically shut down the phone from time to time shutdown means the phone is switched on, network, call normal, but sometimes it will suddenly shut down. This failure There are two main, first, because of poor contact between the battery and battery contacts cause; two power IC output voltage is unstable, the power supply circuit of Weld or poor contact, resulting in cell phone blocker protection. Button to shut down the phone as long as no key, it will not shut down a press some key phone automatically shut down, mainly due to the integrated circuits or components Weld of the buttons below.    cellphone jammer contains the charger, car charger and jammer.
Weld parts due to the role of the force at time of press sealing off, causing the phone to shut down. Maintenance, in a targeted manner to strengthen key lower part of the integrated circuit or component welding generally solve the problem. The caller calls shutdown shutdown is the mobile phone can boot, network, can call the phone ringing sound when a call, the phone shut down. This failure appears to be complex, is actually very simple, calls will be shut down? Is nothing more than ringing sound caused. Ring a ring, why would shut down? This is because a lot of ring work when battery voltage BATT + direct power supply, when the ringing of leakage, it will result in phone calls shutdown.   cell phone jammer  has the dynamic jamming range.
