You can switch it ON or OFF and also adjust the sensitivity of the voice activated recording, depending on your needs and preferences. For the most important recordings, however, we suggest to switch off VOR function, so that all (including pauses or silence) is recorded and no word is missed.

Can the recorder be used for discreet/covert purposes? Is there a sound or light indicating that the recorder is in operation?

The voice recorder is small and can be used discretely, there is no sound when it is switched ON/OFF. In default settings there is a red LED light indicating that the device is recording, however, that can be switched on or off depending on your needs and preferences. Just please always make sure that you obey the laws and regulations, we at TROEX do not support any illegal activities.

How to play back a recording? Should I connect to a computer?

You don’t need to connect to a computer, you can play back instantly from the device by pressing the PLAY button. The recorder has a built-in speaker as well as earbuds. Alternatively, of course, you can plug the recorder into computer USB port and copy or play the recordings using computer.


Is the recorder able to record while charging?

Yes, the recorder can record while charging. It is the best first to start recording and then plug the device into the USB port/charger if that is needed. 


Can I use the recorder with a Mac computer?

Yes, the recorder can be used with Mac computer. Just plug the recorder into the USB port for downloading the files and charging (for the new MacBook Pro that does not come with USB-A port you will need to have an adapter). For Mac computer you may need to download a WAV player. We suggest using 5K Player https://www.5kplayer.com/5kplayer-download-mac.htm or similar free player to listen to the recorded files. 

 

In what format does the recorder record?

Recordings are done in WAV format (uncompressed, broadcast CD quality audio files, simple and easy to process). For playback the recorder supports also MP3 format (compressed, lower quality audio file, most widely used on internet). If needed, e.g. if you want to distribute or post a recording online, we suggest using a free online converter to convert WAV to MP3  https://online-audio-converter.com/.


Can the recorder’s display be turned off in playback mode? I want to use it while film processing in a darkroom.

You can change the time the backlight is on (5-30 seconds or always ON). I.e. the display would turn off after 5 seconds, if you set up the device that way. 

 

Is this device password protected?

Yes, there is a possibility to set a 4-digit numeric password 

 

What is the furthest distance the recorder is able to clearly record at?

For the best quality clear recording - a distance up to 10m is recommended. However, one can record also from a further distance of up to 20-30m, depending on level of the background noise etc. 

 

If I have missed a sentence while playing back, can I rewind to that particular sentence or does it go back to the beginning of the recording?

When you listen to a recording or a song you can always move fast forward or backward by long pressing PREV or NEXT button 
 

In addition, there is an A-B Replay function; during playback before the important part press MENU button once to choose point A in the recording, and then press MENU again to choose point B. The device will play A-B interval several times (1-10, depending on the chosen setup). You need to press MENU again to return to normal playback mode 


Can I record telephone conversation with the device?

You can record telephone conversations if you use a speakerphone. However, there is no separate cable to connect the voice recorder directly to a telephone. 

 

Is there a transcription software that can be used with the recorder?

A transcription software does not come with the voice recorder. However, there are several tools available online that can convert your WAV files into text files. We recommend using a combination of Dragon speech recognition software https://www.nuance.com/dragon.html and InqScribe transcription software https://www.inqscribe.com/ to convert your recordings to text format. Both Dragon and InqScribe have free and paid versions to match your needs for transcription of the recordings.

 

Why does the recorder’s screen says “no file”?

There could be 2 reasons for showing "no file" on the screen:

  1. There are indeed no recorded files on the device, i.e. the files have been deleted by user.

  2. If the recorder has been plugged into computer and the files in the RECORD folder have been altered/deleted using computer. In order to fix the problem, please do the following steps:

    1. plug the recorder into computer and backup all the files from RECORD folder to your computer 

    2. delete the RECORD folder (using computer) and then eject the recorder from your computer

    3. now, once you switch the recorder on and start recording again, the RECORD folder is recreated again and the new recordings are automatically saved there (and you should be able to play them from the device)

If the above steps do not help you will need to re-format the recorder’s disk.
