VAS (Voice Activated System) recording
When the VAS recording function is turned on, if the unit is in recording pause mode, the unit
will automatically start to record as soon as it detects audio at a level above a certain threshold.
The unit will pause recording when the detected audio level falls below the threshold. VAS
recording is available only when ALC is set to ON.
Note:
· Audio at a level below a certain threshold will be undetected and will not be recorded. If
you are planning to record important audio, set the VAS recording to OFF.

threshold by following the procedure in the "Setting the voice sensing level (VAS value)"
section below.
· If you start recording while the VAS function is turned on, the first two seconds or so will
be recorded with no exception.
Setting the voice sensing level (VAS value)
You can adjust the voice sensing level in five steps (1–5) to accommodate the source
volume level. A larger value will increase the voice activation sensitivity so recording will be
triggered by lower-level audio. If the value is too small, the recorder may not detect audio.
Set the microphone sensitivity (see
that the VAS function can work more effectively.
