Detection status:
When

is set to
On
in
the Audio detection tab, the detection status is
displayed.
If excessive sound is picked up by the microphone,
“Detected” appears; otherwise “Non-detected” is
displayed. The input volume is indicated in a bar that
helps you to calibrate detection levels.
Notes
• Test audio detection to confirm that it is functioning as
desired.
• The audio detection function sets the detection level
automatically according to the statistical samples of
input volume and the sensitivity. Thus, the detection
level may differ even with the same sensitivity.
• The detection of input volume cannot be updated
when the
Audio detection
tab is open. This means at
this time the detection level is not adjusted
automatically according to the input sound. According
to the characteristics, test audio detection when the
Audio detection
tab is open.
• Before setting sensitivity, in order to optimize
detection, place the microphone in an ordinary
location and sound environment for about
3 minutes before opening the
Audio detection
tab.
• The Audio detection alarm is off during playback of
audio files.
• The Audio detection alarm is off while uploading
audio (from a computer).
