With the built-in Voice Guidance of the recorder turned on in the menu, Olympus 
Sonority will automatically check the state of the Voice Guidance files in the 
recorder. If the recorder lacks any of the required files, the 

Upload File 

dialog 

box will appear. 

 
 
 
 
 
 
 
 

Click the [

OK

] button. The Voice Guidance files will be uploaded. 

 

Uploading Voice Guidance Manually 

To manually upload the Voice Guidance in a desired language, perform the 
following steps: 
Connect the recorder with the Voice Guidance capability to the computer and 
open Olympus Sonority. 
Select the [

Device

] > [

Upload Voice Guidance Files

] menu option. The 

Transfer Voice Guidance Files

 dialog box will appear. 

 
 
 
 
 
 

 

 
 
Voice Guidance files that can be uploaded are listed in the drop-down list. Select 
the desired Voice Guidance language to upload and click on the [

OK

] button. 

The Voice Guidance in the selected language will upload to the recorder. The 
Voice Guidance file set to the primary supported language in the recorder will be 
overwritten with the new Voice Guidance file in the selected language. 

The battery ran out while I was recording a file, and now I can’t find 
or play the file. Why? 

If the battery runs out of power during the recording of a file, the recording in progress 
will be lost because the file header will be unable to close. It is crucial to change or charge 
the battery once the battery indicator shows only one hash mark of power remaining.   
Removing the battery while the recorder is in use may also corrupt a file.
