What are the main features of this model?

The Olympus VN-240PC digital voice recorder records in ADPCM (Adaptive Differential Pulse Code Modulation) WAVE audio format. The three recording quality modes provide options for recording high-quality sound files or expanding the memory capacity by using a lower-quality recording mode. The VN-240PC also has options for setting an alarm.The microphone and earphone jacks allow the use of audio accessories.

The bundled Digital Wave Player software and USB cable enable the downloading of audio files to a computer, where they can be managed and archived. The Digital Wave Player software supports the renaming of audio files and creating custom folders for archiving files.

What is ADPCM?

Adaptive Differential Pulse Code Modulation (ADPCM) compresses files by saving them as WAVE files with a bit depth of four bits rather than the 16 bits typical of other audio formats.  It also uses the built-in flash memory more efficiently by comparing a sound wave to a previous sound wave and digitizing the difference.

The support software for Olympus digital voice recorders that use WAVE files is Digital Wave Player.

Note:WAVE files are very large and difficult to e-mail because of their size. If you are required to regularly e-mail files for transcription, you may wish to consider an Olympus digital recorder that uses the DSS audio format.

Return to Top

What is the DSS audio format?

Digital Speech Standard (DSS) is a proprietary audio compression format jointly developed by Olympus, Philips, and Grundig. DSS compresses files approximately 12 times, so it is an ideal format for transferring files by e-mail. The DSS compression format also extends the recording capacity of the recorder's flash memory due to the smaller files it creates.

The VN-240PC does not support the DSS audio format.

I recently purchased a newer VN-Series recorder that shipped with Digital Wave Player version 2.1. Will this software support my VN-240PC?

Digital Wave Player version 2.1 is backward compatible with the VN-120PC through the VN-960PC and also with the VN-2100PC, VN-3100PC, and VN-4100PC. Digital Wave Player v.2.1 must be installed to support the VN-2100PC, VN-3100PC, and VN-4100PC. Digital Wave Player v. 2.1 is required for Windows Vista compatibility.

Can I save my audio files to an audio CD?

Audio files from VN-Series digital voice recorders cannot be saved to an audio CD for playback in a music player. This is because the bit depth used to expand the memory capacity in the recorder cannot be converted into a format with the file properties necessary to create an audio CD. The files can be saved to a data CD that can be played on a computer using the bundled Digital Wave Player version 2.1 software.

How much recording time is available in the VN-240PC?

The length of the potential recording time available in the VN-240PC is governed by the recording quality mode that is selected. An HQ (High Quality) mode recording uses more memory than an LP (Long Play) quality mode recording because the HQ mode makes a more-detailed digital record.

The table below shows the approximate maximum dictation recording times possible in the VN-240PC in the different quality modes:

 
Quality Mode Maximum Dictation Recording Time
HQ mode 1 hours 28 minutes
SP mode 2 hours 13 minutes
LP mode 4 hours 5 minutes

How is the VN-240PC turned off?

The HOLD switch is the power ON/OFF switch on the VN-240PC.  Set the switch to HOLD when replacing the batteries to preserve the time and date settings.

How is the recording volume controlled?

The VN-240PC always records at 100% volume level to prevent accidentally recording with the volume set too low.

The recorder has two levels of microphone sensitivity:

  • LOW is a low sensitvity level used for close-up recording.
  • HIGH is a high sensitvity level used in conference or lecture situations.

Microphone sensitvity is set in the recorder Menu. The function is identified by an icon that looks like a microphone.

How does the ALARM function work?

The ALARM function can be set to play back an audio file at a pre-determined time. This means the VN-240PC can be used for audio reminders or as a travel alarm. An alarm setting must be attached to a particular file in a particular folder. The recorder does not have to be set to the folder being used--when the alarm time comes, the recorder finds the file.

To set an alarm:

  1. Select or record a message file to be linked to the alarm.
  2. Open the Menu by pressing the MENU/FOLDER button for three seconds.
  3. Using the STOP or PLAY buttons scroll to the ALARM menu icon (looks like a dot with double-parentheses around it).
  4. SET flashes on the LCD screen. Press the ENTER/INDEX button.
  5. Enter the alarm time by setting the hour with the STOP or PLAY buttons. Press the + button to select the minutes setting, and set the minutes using the STOP or PLAY button.

How are folders created and renamed in Digital Wave Player?

Digital Wave Player allows you to create and rename folders and subfolders within its storage hierarchy in order to facilitate efficient management of large numbers of audio files.

In the example below, Folder B has been divided into a series of subfolders. The able and baker folders are subfolders of Folder B. The charlie folder is a subfolder of baker.


Subfolders can be named with up to 20 characters. Spaces are allowed, but some characters--such as backslash, ampersand, and colon--may not be employed because they serve other functions in computer languages. Using purely numeric naming models may create problems when archiving audio files, therefore alphabetical or alphanumeric combinations are recommended.

To rename a folder, right-click on it, then left-click Rename Folder and overwrite the folder name.

To create a new folder or sub-folder, right-click on the folder and then left-click on Create Folder. In the Create New Folder dialog box, type in the new folder name and click OK.

How are files renamed in Digital Wave Player?

Files can be renamed in Digital Wave Player with up to 17 characters. Renaming a file with more than 17 characters will render the file unplayable. Spaces are allowed, but some characters--such as backslash, ampersand, and colon--may not be employed because they serve other functions in computer languages. Using purely numeric naming models may create problems when archiving audio files, therefore alphabetical or alphanumeric combinations are recommended.

To rename a file, right-click on it, then left-click on Rename File and overwrite the file name. Optionally, you may instead highlight the file, select Rename File in the Edit menu, and overwrite the file name.

What is the purpose of the "S" folder?

This folder has subfolders that can be used to organize the sound files by date. There is a folder for each date between Jan. 1 and Dec. 31. While each subfolder can hold up to 10 files, the S folder itself has an overall limit of 100 total files.

Return to Top

Why can't I move a file between folders?

The number of recorded files in the destination folder may have reached the limit of 100 files. Make sure that you haven’t transferred files to or from the "S" folder.
