 Switch OFF: While the switch is ON, if you push the power button to the “OFF” position, the device will save your recordings and be switched off.

Push the power button to the “ON” position, and the device will automatically start recording. During playback, since the earphones would need to be plugged in, if you unplug them, the device will automatically enter recording mode.

Turning the Recording Indicator Light ON/OFF: While in recording mode, press “+”once to turn the indicator light on. The light will start flashing red every 2-3 seconds. There are situations where you might want to have the indicator light on to check whether the device is still recording. To switch the indicator light off completely (while continuing recording), press “-” once. 

Saving Recordings: There are 2 ways to save your recordings: 

  1. While recording, if you switch the recorder OFF, the device will save your recording, and shut down.
  2. While recording, if you plug in the earphones, the device will automatically save the current recording, and start playing the recording it just saved.
  • Playback of Recordings: plug your earphones into the earphone jack, and then switch the device ON. Now the device will start to play recordings in your RECORD folder. During playback, the indicator will flash blue.
  • Playback of Music: Plug your earphones into the earphone jack, and then push the power button to the “ON” position. The device will start to play back recordings in your RECORD folder. If you hold down your long the “+”and “-” keys together, within 3 seconds, it will switch to playing back music in your device (if there are music files on the device). NOTE: If there are no music files on the device, this switch to playback music will not occur. During playback, the light will flash blue.

During playback of files, press “+” or “-” to either switch to the next or the previous track respectively.

During playback, hold down the “+”and “-” keys together for 3 seconds to switch between the MUSIC and RECORD folders. (If there are no music files on the device, this function will not work).

During playback, hold down the “+” or “-” keys to increase or decrease volume.

While recording, hold down the “+” key for 3 seconds in order to turn on the voice activated function. Hold down the “-” key for 3 seconds to turn off the voice activated function. If the blue light is remains on, it means the recording is paused in voice activated mode. If the blue light is off, and the red-light flashes, it means it has resumed recording in voice activated mode).

NOTE: The voice activated recording function is not available by default on this model, but is an optional upgrade, and if you would like to have this function enabled on your unit, you need to contact customer support to help you update your device through a free firmware upgrade.

Sometimes there are various misconceptions about voice activated recording, which may lead to certain unrealistic expectations that recording will simply switch off when someone stops speaking and start again when they resume speaking again. This is not always so.

The voice activated recording function (when enabled) on this device works on a threshold of -40dB. As you can well imagine, this is a pretty low threshold. Any ambient sounds above this threshold that the device ‘hears’ will keep it in recording mode, even in a quiet environment. This might lead to the wrong conclusion that the voice activated recording feature is not working properly.

In this case, the fact is that the recorder is not intelligent enough to know which sounds are ‘desirable’ and which ones are not. Due to this, it records everything it ‘hears’ above the threshold.

This might also lead to recordings that are longer than necessary and in order to eliminate the extra lengths of undesirable audio, editing might be required. 

We have provided a video tutorial on our website showing you how to use Audacity (free software) to edit audio.

Connect your device to a computer (like you would with a normal flash drive), and find the removable drive on computer. When you open the drive, you will find the “SetTime” utility.

Now switch the recorder ON and double-click the SetTime.exe file. You should get a message on your computer saying the procedure was successful. You can now go ahead and eject the device from your computer. 

Please remember: Do not switch off your device at this time. After 10 seconds, you may switch the recorder OFF.

Connect to your computer with the attached USB cable, or your android phone cable. Connecting to a computer is the same as connecting any other flash drive.

When you need to remove the device from your computer, please eject it safely through the computer. Removing the recorder without ejecting it properly and simply yanking it out of a USB port may lead to your recorder being damaged and loss of data.

All recordings are saved in the RECORD folder on your device. Each new recording file will be named sequentially, starting with REC001, REC002 and so on.

NOTE: Your device has an auto segmenting function, which simply means that when a single recording reaches a file size of 2GB, it will automatically save the recording, and start a new file.

Charge it with your Android phone adapter or use the provided cable to connect it to your computer. When charging, the blue red light will come ON. It usually takes 2 hours to be fully charged. Once it is done, the light will go off.

There is a reset button on the device close to the earphone jack. If you need to reset the device, simply push into this with a needle, hold it down for a couple of seconds and then let it go. This should reset the device.

Once you’ve recorded something on the D-VRMP1, it is very simple to access your recordings.

You simply plug it into the USB port of a computer, and you can access the device as a normal USB drive. Before plugging it in, please make sure that the switch is in the OFF position.

Once you are in Windows Explorer, just open up the window for the D-VRMP1. It will typically show up as a removable drive. In the window for the D-VRMP1, you will see a folder called ‘Record’.

Once you open this, you will find that it has your recorded file with a .wav extension.  You can play this file normally as you would any other media file – either through Windows Media Player, or any other player of your choice. 

If the 8GB storage on the device gets filled up, the recorder will save the file and stop recording.

You would need to move files off the device by plugging it into a USB port on a computer and move the files from the device into another folder to create space for future recordings.

NOTE FOR WINDOWS 10 USERS: If you are on Windows 10, please use Windows Media Player or VLC Media Player for playback of files, because Groove Player is not well equipped with all the codecs, and you will probably get an error saying that you have a file with incompatible format. 

While using the D-VRMP1 with a Windows computer is fairly simple and straightforward, it takes a few minutes extra to get it set up with a Mac. But don’t worry, it’s not hard.

Time-stamping on Mac OSX:

Ideally, if you have a Windows partition on your Mac, you can run the SetTime.exe from that partition to enable time-stamping on your device.

About the time-stamping on Mac – this is an optional feature.

Unfortunately, the SetTime application on the device is a Windows only application – which was developed by a 3rd party.

We are in the process of developing our own Macspecific app, but it is not yet ready.

We apologize for the inconvenience. We hope to have it ready really soon.

The workaround would be to run it under Parallel Desktops for Mac or via Bootcamp – or use a PC.

The other option would be to name the file itself based on the event – say – “Birthdayparty-Today’sdate” – something of the sort.

However, as a recorder, the device will still work with recordings and playback would be via VLC Media Player on a Mac.


In order to play your recordings on a Mac:

Go to Google and search for: “VLC for MAC download”. 

Select the correct player for your Mac operating system. (It’s free to download).

Drag the VLC icon to your application folder.

After your VLC player is installed, open the WAV files from your recorder. When you alternate click the file, you should have the option to “open with” — select to open with your VLC player, or just simply drag the WAV files into the VLC player.

Now turn up the volume on your Mac. You should be able to hear the recordings done on your D-VRMP1 USB Voice Recorder.

If you need to convert your WAV files to MP3, we recommend using the “Convert” feature in VLC itself, or third party software like Emicsoft Video Converter for Mac.

You can also use Quicktime Player for Mac OSX.

Alternatively, you can download the Mplayer app from the Apple App Store.

Just as you use VLC Media Player for Windows or Mac OS, this software is free to download and install on your Chromebook too. 

You just need to make sure that you are selecting the version of VLC Media Player for Chromebooks.

Simply open your file with VLC Media Player (once installed) and play your recordings.
