Make sure the cell phone is shielded by cell phone jammer

When a component is suspected, the same components installed experiments, the effect was immediate. If instead of troubleshooting the original components have been damaged, such as to replace the problem persists, the problem is not this component should continue to find, instead, the law applies to all components of the cell phone. Can be used under certain circumstances, single-frequency components instead of the dual-band components, such as the commonly used 14-series single-frequency power amplifier instead of the Hitachi dual-band amplifier, but only in the areas of GSM bands. Here is the introduction to omnidirectional antenna and directional antenna of cell phone jammer.
Motorola cell phones, can also be used to test card loaded with maintenance instrument to test function, detect the cell phone receiver, launch function is normal, can enter the emission state of the transmitter circuit overhaul. Software law: supply voltage unstable, blowing temperature welding memory or software program itself, could easily lead to memory itself, bad performance software data loss or confusion, lead to the computer, network or software failure, usually disassemble maintenance-free instrument to rewrite the software data, if the online font or chip can be removed with 48 programmer programming, such as write into or display fonts damage, indicating that memory itself is damaged. Make sure the cell phone is shielded by cell phone jammer.
Antenna method: simple and practical, repair the fault of the RF circuit, about 10 cm long wire or solder wire, tweezers, oscilloscope probe as a fake antenna, respectively, connected in the input and output of the signaling pathway, such as a component input cell phone working properly connected to the dummy antenna circuit after the false antenna normal, and then to leave the antenna to the output of this component, such as not working properly, the problem in this component. Adjustment Act: due to the launch of the transmitted signal is too strong due to shut down, too weak and cause failure of launch reset, redial, repair or replace the power amplifier power control circuit effect. It is recommended using the directional antenna of cell phone jammer.
