Digital voice recorder is an essential device for students to record lectures, seminars, group discussions, etc. It is also commonly used in business for recording meetings, presentations, dictations, notes taking, etc.

Its feature buttons/switches are well explained in the Operating Instruction Manual:
- T-Mark: to add a track mark at a point during recording, pausing or playback, at which you would like to divide a file later or locate during playback. You can add a maximum of 98 track marks to each file.
- Noise Cut: when you set the NOISE CUT switch to “ON”, ambient noise other than the human voice is reduced. A file is played back with clear sound quality because the noise of all frequency bands including a human voice is reduced.
- A-B: to play back a specified section repeatedly
- DPC: Digital Pitch Control to adjust the playback speed in a range from 0.50 times to 2.00 times.
- VOR: Voice Operated Recording starts and stops the recording when sound of a sufficient level is picked up by the microphone. This feature saves valuable recording time by not recording periods when there is little or no sound.
- Intelligent Noise Cut: Sony technology to significantly reduces ambient noise during recording for clearer playback.
- Low Cut Filter: helps reduce the effect of wind noise in your recordings.
- Sync Record: when recording directly from an external device, the Sync Record function can be used to automatically pause the recorder during silence and resume recording when sound is detected.
