   You could delete file or copy file into it, same as your ordinary USB Flash Drive.

   When connected to computer, it will enter connection mode, the device screen will show the “CONNECTION ICON” like the CHAPTER TWO, POINT 13 picture shows.
   All buttons will not work at this situation, if you press M and hold it, it will exit connection mode, and will be failed to connect to your computer.
8. Cannot find my recordings in the recorder
   This mainly caused by the device reading the MUSIC folder, you could press and hold STOP switch back to RECORD folder.
   Or connecting computer, and check whether there is recordings in the device or not.
9. How to Turn ON Voice Activated Function
   Go to Menu Options, find record setting, enter it -> Voice Activated 
   Setting -> AVR mode -> ON, and press M confirm it.
   Now pressing REC, the screen will show VOX, it means you have successfully set voice activated recording function.
10. How to Use the AVR Mode (Voice Activated Function)
    When AVR mode is ON, the recorder will enter voice activated recording mode.
    It will only picks up loud enough decibels voice (any sounds).
    So we could select the best AVR level as we want, and get the best effect of voice activated recording.
    For L157 voice recorder, the AVR level could be selected from 1 -5; 
    The lower number means need higher decibels voice to activated the recorder, and it need louder voice; At level 5, it is very sensitivity, only a very low decibels or quiet speaking could be picked up.
    Also, when voice activated function was ON, press REC, it will record 3 seconds, the device run 3 second to check the recorder was corrected entered recording mode. And then it will only pick up loud enough decibels voice / sound.
11. Press REC, it not recording
    First check, the recording light blink or not.
    Second, can you see VOX on the screen, If so, we suggest you could close the AVR mode, if you do not want this function
    Third, confirm if there is enough free space on the device.
12. Press REC, it shows “OVER RECORD”
    When press REC, it not records, it show “OVER RECORD”, that means the voice recorder memory is full, or you have too many “FOLDER” or “recordings” in the recorder.
    Why this happened? 
    Although you may not record too long time. Sometimes mistakenly RECORD, and SAVE again and again, or copy or create too many “FOLDER” in the recorder disk. Maybe there is some files that cannot be read by the recorder, so you cannot find directly from the recorder
    So you need to format the voice recorder, or connect to computer and have a check, after that format the recorder disk from your computer directly.
13. How to use the A-B repeat function
    During playback, press and hold M, you will see A on the screen, and B is blink, it selected the start point Press and hold M again, select point B Now it will playback between Point A to B
14. The recording is noise
    Don’t recording near computer, electric fans, air conditioner, sound bar that will easily cause noise, the recorder will pickup this statics noise.
15. The recorder auto shut down when I am recording
    Why this happened? 
    The sleeper time function is ON, when set this, no matter you are operating the device, or recording or playing, it will force to shut down the device.
    So you could go to System setting - > sleeper time, select OFF and confirm it. You will close the sleep time function. In default, it was at zero
    So you could also try to restore to factory setting when this happened, if not sure how to set the sleeper time.
16. I Cannot Shut Off My Voice Recorder
    When the recorder is charging, or connected to computer, even when the POWER BUTTON ON/OFF was at OFF position, it will still be ON, and you cannot shut off the voice recorder at this status (because the voice recorder directly get power from charging socket or computer).
17. Space is full
    When space is full, you can connect to your computer and back up all the files to your computer, and then delete all the recordings in your voice recorder. (Do not cut off recordings from recorder to computer, this cannot delete file from recorder successfully, and still occupy the disk space)
    The voice recorder has a limited storage at 48GB, so after a while of using, it may be full of storage, you need to back up it on your computer.
