是的，电源指示灯是亮的，机器也正在运行，但是不知怎么的声音就是出不来。
Yes, the power indicator was on, and it was running, but somehow the sound didn't come through.
没有指示灯显示是否运行，没有快进键和后退键，也就没有这类的噪音。
No light to show it is on; no fast forward button and the record button makes a loud noise.
在运行过程中，如果指示灯闪烁5min后长亮，也表示SRS系统出现故障。
In the course of operation, if the indicator light flashes after 5min long bright, also indicates that the SRS system failure.
