TROUBLE SHOOTING

1. No Voice Recordings
   If there is no voice recording or all recordings have been deleted, when device is turned on it will display “no voice recordings” or “no songs” on the screen. Noto worry, go ahead and press REC or M (menu).

2. How to Turn Off the Record Light
   Go to Menu Options -> Record setting -> Up/Down button -> Record led -> select OFF. When recording, the record light will not light up or flash.

3. Format Error
   This usually happens because of three reasons.
   During recording, pushing down the POWER BUTTON to OFF position will cause file damage.
   Before switching off recorder, first press STOP to save the recordings.
   The recordings time is less than 5 seconds.
   Computer does not support the .wav file. The recordings were saved as .wav format. For WINDOWS 10 or MAC user who may encounter with this issue, don’t worry. Download the free MplayerX /VLC Media Player to solve this issue.
   http://mplayerx.org http://www.videolan.org/vlc/
   Record at MP3 format, so recordings will be more widely supported by different computers.

4. Disk Error
   Due to static shock, like over charging, recorder cuts off its power when the formatting process doesn’t complete, and device loses system firmware.
   How to Rescue: Keep power button at OFF position, connect device to Windows computer, and format the recorder disk again. Device will be normal.
   How to connect to a computer:
   Use the enclosed cable to connect to your computer, or use an android phone cable.
   If device fails to connect to the computer, contact support@evistr.com to get a quick solution.
   Or, for the simple way, change to a new socket or use a new cable. (For example, this issue also happens when failing to connect a flash drive to a computer.)

5. Failed to Connect to Computer
   Before connecting the recorder to a computer, turn off the recorder.
   When connecting to a computer, do not press any buttons on the recorder or do any operations on the recorder. Otherwise, it will exit connection mode, and fail to connect to the computer. At this status, it will only charge the voice recorder.
   For more failed connect to computer issues, please contact us. We will reply promptly.

6. Can Recordings Be Deleted from the Computer?
   Yes. When the recorder is successfully connected to a computer, find it as the removable drive name “L157.”
   All recordings are saved in a folder named “RECORD” in the drive.
   You may delete the file or copy the file onto an ordinary USB Flash Drive.

7. When Connected to a Computer, the Buttons Do Not Work
   When connected to computer, the voice recorder is in connection mode. The recorder screen will show “CONNECTION ICON” and no buttons will work.
   To restore button function, press M and hold. Device will exit connection mode.

8. Cannot Find My Recordings in the Recorder
   When first opened, the device will first read the Music Folder. Press STOP to switch back to recordings folder.
   The recorder can also be connected back to the computer to check whether there are recordings in the recorder disk.

9. Turn On Voice Activated Function
   Go to Menu -> Up/Down button to Record Setting -> press M -> Up/Down to Voice Activated Setting -> press M -> select AVR mode, and press M to confirm.
   Now press REC. You will see VOR on the screen which means voice activated recording function is set.

10. How to Use the AVR Mode (Voice Activated Function)
    When AVR mode is selected, the device will only pick up a loud enough decibel sound or voice.
    Adjust the voice activated sensitivity in record setting.
    Select the AVR level to get the best effect for voice activated recording.
    For the L157 voice recorder, the AVR level can be selected from 1 -5. The lower number requires a higher decibel voice to activate the recorder. In other words, a louder voice. At level 5, the recorder is very sensitive and will pick up quiet speaking.
    Note: When the voice activated function is ON, press REC. Device will record 3 seconds to check if the recorder is correctly entered into recording mode. It will only pick up loud enough decibels of voice /sound.

11. Recorder Not Recording
    Check to see if the recording light is blinking.
    Additionally, see if VOR is on the screen.
    If VOR is on the screen and light is blinking, it means the voice activated function is ON. During this setting, it will only record when a high enough decibel sound is detected. You may go to Record Setting, find AVR sensitivity, and adjust.
    Turn off the AVR mode if this function is not needed.

12. Why Does Recorder Playback in Random?
    Go to Play setting, close the shuffle function.

13. How to Use the A-B Repeat Function
    During playback, press down M (menu). A appears on the screen and B blinks. Recorder selected the start point. Press down M again, select B. Now recorder will playback between Point A to B.

14. The Recording Has Unwanted Noise
    Avoid recording near a computer, electric fan, air conditioner, or sound bar that will cause noise. The recorder will pick up this static noise.

15. The Recorder Auto Shuts Down While Recording
    This happens when the sleeper time function is ON.
    When operating the device, or recording, or playing music/recordings, the sleep timer function will force a shut down on the device.
    Go to System setting – > sleeper time. Select OFF and confirm. This closes the sleep time function.
    You can also try to restore the recorder to factory settings when this happens if you’re not sure how to set the sleep time.

16. Cannot Shut Off My Voice Recorder
    When the recorder is charging, or connected to computer, even if the POWER BUTTON ON/OFF is at OFF position, recorder will still be ON. The voice recorder cannot be shut off because the voice recorder is directly getting power from the charging socket or computer.

17. How to format the recorder
    Press M (menu), enter menu options.
    Select System Setting, press M to enter.
    Select Format Device, Press M to enter.
    Enter Format Disk, select Yes.
    Press M to confirm and start formatting. After formatting is completed, all files on the recorder will be deleted, and all storage (8GB or 16GB storage) will be available on voice recorder again.
    Note: Do not shut off the device during disk format

18. Space is full
    When the storage space is full, connect to a computer, copy recordings, and save them to the computer. Delete all the recordings from the voice recorder. The voice recorder has a limited storage at 8GB or 16GB. After a while of using, the recorder may be full and needs to be backed up onto a computer.
    Note: Do not cut off recordings from recorder to computer. This will cause an unsuccessful transfer, and the files cannot be deleted from the recorder successfully.
