维修注意事项:修机时不要急于动手,首先要全面观察故障现象,判断是否属机器自身质量问题,如:使用电池时,电池电压是否过低,电流是否充足,电源插头是否插好,耳机插头是否插好,磁头表面是否干净、无损等。因不正确使用造成的假象故障,排除这些因素之外,打开机器后要根据电路原理分析、故障产生原因以及初步判断故障点,并检查线路板的铜片或连线是否有脱落和断裂,元器件是否有虚焊或碰脚短路等
Repair Notes: Do not rush to repair the machine, first of all to observe the phenomenon of failure, to determine whether the quality of the machine itself, such as: the use of the battery, the battery voltage is too low, the current is sufficient, the power plug is plugged in, the headset plug Is inserted, the head surface is clean, non-destructive. Due to improper use caused by the illusion of failure, to exclude these factors, open the machine according to the circuit analysis, the reasons for the failure and the initial judgment of the point of failure, and check the circuit board copper or wiring is off and broken, Yuan Whether the device is Weld or touch the short circuit
