FREQEUNTLY ASKED QUESTIONS

• No Voice Recordings
  If there is no voice recordings, or we have deleted all recordings on the device, when we turn on, we will see “ no voice recordings” or “no songs” on the screen. Don’t worry, we could just go ahead to press REC or M (menu)

• How to Turn Off Record Light
  Go to record-setting -> Record led -> select OFF, so when recording, the record light will not light up or flash

• Format Error
  Format Error, this usually happens from 3 aspects:
  During recording, directly push down the POWER BUTTON to OFF position, that will cause file damage, before switch off voice recorder, we need to press STOP save the recordings first
  The recordings time length is less than 5 seconds, like ZERO second recordings file
  Computer do not support the .wav file. The recordings were saved as .wav format. For WINDOWS 10 or MAC user may encounter with this issue. Don’t worry we could download the free MplayerX / VLC Media Player to solve this issue http://mplayerx.org/ http://www.videolan.org/vlc/
  Try to Record at MP3 format, so it will be more widely supported by different computers

• Disk Error
  Due static shock, like over-current charging, cut off its power when the format device didn’t complete, so it lost system firmware.

• How to Rescue:
  Keep its power button at OFF position, connect to the windows computer, and format the recorder disk again, things will be normal
  How to connect to a computer
  Use the attached cable connect to computer, or use the android phone cable
  If we failed connect it to computer, we could contact support@evistr.com get a quickly solution.
  Or we could go to the simple way, just change a new socket or new cable. Because this issue usually happens like we failed connect flash drive to computer, they are the same issues.

• Failed Connect to Computer
  Before connecting the voice recorder to computer, we should turn off the recorder And when connect to computer, we shouldn’t press any buttons of the voice recorder, it means we shouldn’t do any operation of the voice recorder, Otherwise, it will exit connection mode, and failed connect to computer. At this status, it will only charge the voice recorder For more failed connect to computer issue, please kindly contact us. We will reply to we as soon as possible.

• Can I delete recordings from computer
  Yes, when the recorder was successfully connected to computer, we should find it as a removable drive name as “L157”, and all recordings was saved in a folder names “RECORD” in the drive. we could delete file or copy file into it, as we used as an ordinary USB Flash Drive.

• When Connect to computer, the buttons not work
  When connected to computer, it was at the connection mode, the voice recorder screen will show the “CONNECTION ICON”. All buttons will not work at this situation, if we press M and hold it, it will exit connection mode, and will be failed to connect to computer.

• Cannot find my recordings in the recorder
  This mainly because when we open the voice recorder, it reads the MUSIC folder, we could press down STOP switch back to recordings folder Or we could connect it to computer to check whether there is recordings in the recorder disk.

• How to turn on voice activated function
  Go to menu options, find record setting, enter it , select Voice Activated Setting, open AVR mode, and press M confirm it. Now press REC, we will see VOR on the screen, it means we have successfully set voice activated recording function

• How to Use the AVR Mode (Voice Activated Function)

• When AVR mode is open, the recorder will enter voice activated recording mode. It will only picks up loud enough decibels voice (any sounds). So we could adjust the voice activated sensitivity in record setting, 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 opened, 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.

• Press REC, it not recording
  First check, the recording light blink or not Second, can we see VOR on the screen If so, it means we have open the voice activated recording function, during this setting, it will only records when high enough decibels sound detected, we could go to record setting, find AVR sensitivity, and adjust it. It helps But we could turn the AVR mode, if we do not want this function 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 we have too many “FOLDER” or “recordings” in the recorder. Why this happened? Although we 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 s some files that cannot be read by the recorder, so we cannot find directly from the recorder So we need to format the voice recorder, or connect to computer and have a check, after that format the recorder disk from computer directly

• Why it is only playing 10 seconds?
  This is because we have entered view playing playback mode, it will playback 10seconds of each file. We could set to repeat all, and fix this issue.

• Why it playback in random?
  Go to play setting, close the shuffle function

• How to use the A-B repeat function
  During playback, press down M, we will see A on the screen, and B is blink, it selected the start point Press down M again, select point B Now it will playback between Point A to B

• The recording is noise
  Don’t record near computers, electric fans, air conditioners, sound bar that will easily cause noise, the recorder will pickup this statics noise All manuals and user guides at all-guides.com

• The recorder auto shut down when I am recording
  Why this happened? The sleeper time function is ON, when set this, no matter we are operating the device, or recording or playing, it will force to shut down the device. So we could go to System setting – > sleeper time, select OFF and confirm it. we will close the sleep time function. In default, it was at zero. So we could also try to restore to factory setting when this happened, if not sure how to set the sleep time.

• I Cannot Shut Off My Voice Recorder
  When the recorder is charging, or connected to a computer, even when the POWER BUTTON ON/OFF was at OFF position, it will still be ON, and we cannot shut off the voice recorder at this status (because the voice recorder directly get power from charging socket or computer)

• How to format the recorder
  Press M (menu), enter menu Select System Setting, press M (menu), enter it Select Format Device, Press M (menu), enter it Enter Format Disk, select Yes Press M (menu), confirm and start to formatting, after formatting completed, all files on the recorder will be deleted, and now we will get 8GB or 16GB storage on voice recorder again. Do not shut off the device during format disk

• Space is full
  When space is full, we could connect to computer, and copy out recordings, and save it to computer, and then delete all the recordings in 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 8GB or 16GB, so after a while of using, it may be full of storage, we need to back up it on computer We will regular update our E-book, based on our customer feedback. We hope to get more interaction from customers, and let us know more we could do, we could visit more of this information from our website:
