The application of phone includes conference rooms and offices

phone has the 24-hour after service hotline support and network support.
The reaction of the emission current can not call, specific performance: dial 112 when you press the launch button, the current from the standby current increased to 100mA or so horde for some time and then fall back to the standby current, such failure is generally launch the final stage of the problem should focus on check the antenna switch (or combiner), emission filters, amplifiers and other components, specific measures to remove the antenna switch and emission filter filter, emission filter filters the channel connection directly with a small capacitor, and then two thin ( about 10cm) respectively welded to the receiver front-end and transmit signal output, then dial 112 test machine. If the phone can play, then the antenna switch or transmitter filter filter took part in question; play no telephone, the current response as before.After the first procedure of producing phone has been finished.Standby automatically charge of maintenance "the power of MT6305, MT6205 or MT6218 etc. CPU such combination, often encountered automatic charging performance of the automatic" charger connected "and" charger has been removed ", check the charging tube, If not, then power is unlikely, basically CPU sealing off, I took several machine are the CPU, many of which are broken, or pressure. a boot to appear immediately Telsda a few lines of English and constantly re-starting the storage of MP3 IC to Alice. MT series appear photographic, archival storage solution of the error. The application of phone includes conference rooms and offices.
IC can be stored for a, you can also enter the download mode, U disk in the computer format in the file management inside the 0 byte 1 in the computer format. Change MP3 storage blocks, the market there are two kinds of Samsung and Toshiba MT boot does not maintain the maintenance of first power supply 6305 33 feet 2.8 to maintain voltage, if it would change the power, If you do not remove the CPU to look at the power supply 33 feet to CPUC3 feet did not break. Also can not rule out the software. CPU and Spreadtrum Communications 6600CPU appear the headset headphones detect foot ground can. The power phone is 12W with 3W for each antenna.Including after the supply of the receiver, the receiver one by one to receive all of the wireless channel in the air was electric. These channels a total of 124 +374 = 498. This time on the power supply current of the "search network", but more detailed work status to the oscilloscope and spectrum analyzer measurements to know (for example, the VCO VT measured values in the following instance of the N8310 phone), time measurement good machine compared (one of the three magic weapons). When mobile phones and base stations.
