What are the main features of this model?

The Olympus VN-120 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-120 also has options for setting an alarm. The microphone and earphone jacks allow the use of audio accessories.

The recorder will not allow me to record, what could be wrong?

Check the following:
Press the STOP button repeatedly while the recorder stops, check if the display shows:

  • The remaining recording time in the selected folder may have reached "00:00".
  • The number of files is 100
Check if the display shows FULL by pressing the REC button. The number of files of the same date in folder S may have reached 10. Your recorder could be full, please delete some recordings.

What is the major difference between the VN-120 and the VN-120PC?

The VN-120PC ships with a USB cable and software so that recordings can be downloaded to a computer for storage, management and editing. The VN-120 cannot be connected to a computer.

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.

How much recording time is available in the VN-120?

The length of the potential recording time available in the VN-120 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-120 in the different quality modes:

 
Quality Mode Maximum Dictation Recording Time
HQ mode Approx. 43 minutes
SP mode Approx. 1 hour 5 minutes
LP mode Approx. 2 hours 1 minute

Notes: Recording times are estimates based on the recording of one continuous file. The total available recording time may be less if several files are recorded. Recording time is a measure of memory capacity and is not a guarantee of battery life.

How is the VN-120 turned off?

The HOLD switch is the power ON/OFF switch on the VN-120. Set the switch to HOLD when replacing the batteries to preserve the time and date settings.

How is the recording volume controlled?

The VN-120 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 is the playback volume controlled?

The playback volume is controlled using the VOLUME control dial on the right side of the recorder.

How is the playback speed controlled?

Pressing the PLAY button during playback changes the playback speed to -20% normal speed. SLOW appears on the LCD screen during slow playback. Pressing PLAY a second time changes the playback speed to +30% normal speed. FAST appears on the LCD screen during fast playback. Pressing the STOP button stops the playback and resets the recorder to normal playback speed.

How can I format the VN-120?

What is VCVA?

Variable Control Voice Actuator (VCVA) is a function that configures the recorder to record automatically only when sound is detected at a pre-set level and to stop when the sound drops below the threshold level. The purpose of the function is to eliminate "dead air" during recordings, thereby conserving memory and shortening file times.

VCVA is enabled in the recorder menu.

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-120 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 button, 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 button.
  5. Enter the alarm time by setting the hour with the STOP or PLAY button. Press the + button to select the minutes setting, and set the minutes using the STOP or PLAY button.
  6. Press the ENTER button to set the time.

When the alarm goes off, it will beep for five minutes or until any button is pressed to play the recording. The alarm will sound even if the HOLD switch is in the power OFF position. The alarm will sound daily until the ALARM function is set to OFF.

You may have reached the limit of 100 files. To verify this, press the REC button. If the LCD displays the word “FULL,” files must be deleted to allow for new recordings. If the LCD does not display the word “FULL,” then the number of files may have reached the limit of 10 files in a date subfolder in folder “S.” Files will need to be deleted from that folder.
