cell phone jammer has no radiation towards the human body

cell phone jammer can strengthen the discipline in the examination room.
0.001C (ie, 0.6mA) then set up current, the charging time of 10 hours because the accuracy of the instrument, has been unable to obtain accurate, but the capacity is calculated only from 0.01C to 0.001C 1.7mAh to the use of more than seven hours in exchange for mere thousandths less than the capacity of no practical significance. Moreover, there are other charging method, such as pulse charging lithium-ion battery reaches 4.2V voltage limit, it is no cut-off minimum current judgment stage, generally 150 minutes after it is 100% fully charged. many phones are pulse charging method was once fully charged cell phone display, and then the cradle for charging to to confirm the extent of mobile phone fully charged, this test method is less stringent. 
Share of hard disk space is much larger, but the WAV file playback is the best, WAV files directly reflect the size of the value of a sound each time, 1 minute 44khz sampling rate WAV files will occupy a 10M hard disk space AAC is the Nokia expand the cooperation with Fraunhofer IIS, AT & T, Sony, Dolby, jointly developed known as "the 21st century, data compression," Advanced Audio Coding ("AAC) audio format to replace the location of the MP3 . AAC applicable to of 160Kbps multi-channel high quality audio within the coding bit rate in of 8Kbps single-channel voice quality, and allows for multimedia encoding and decoding.  cell phone jammer has no radiation towards the human body.
AAC increase in such a perfect reproduction of the stereo effect sound scan of the bit stream, multimedia control, excellent noise reduction and other MP3 features not available to make able to perfectly reproduce CD-quality audio compression. WMA stands for Windows Media Audio, Microsoft launched a par with the MP3 format, a new audio format. WMA in the compression ratio and sound quality are more than the MP3 is far better than the RA (Real Audio), can produce better sound quality even at low sampling frequency, plus WMA Microsoft Windows Media Player, do its powerful backing, so once launched on to win acclaim. The advanced high-frequency wide band of cell phone jammer and interference technology combines well.
Battery memory effect refers to the irreversible failure of the battery, that battery failure can restore performance. Memory effect refers to the battery for a long time subjected to a particular work cycle, automatic maintenance of this particular tendency. This first defined in the nickel-cadmium battery, bag of nickel-cadmium battery does not exist memory effect, the sintering battery memory effect. nickel metal hydride (commonly known as nickel-metal hydride) batteries from the memory effect of the constraints defined because the nickel-cadmium battery technology improvements, the above The memory effect has been greatly reduced, while the other, a phenomenon that replaces the definition of the nickel-based batteries "lattice". The maintenance can prolong the life time of  cell phone jammer .Therefore, the customer should select cell phone jammer according to their requirements
