Recommendations for a trial
recording
The recording environment varies from situation to
situation. The dimensions of a room, the loudness
of speech, or a location near noisy equipment can
make a dierence, etc. The desired sound quality also
diers depending on the purpose of the recording.
Therefore, a trial recording is very useful to avoid
missing an important recording, or to create an
environment to record sound with the ideal quality.

To reduce recording noise
Touch noises may be recorded when you touch the
IC recorder during recording. Try to avoid touching
the IC recorder until the recording ends.
Move the IC recorder far from the sound source, or
eliminate the noise.
Select the best recording mode according to the
situation. We recommend you to set the recording
mode to the high-quality mode (“192kbps(MONO)”
(SHQ) or “128kbps(MONO)”(HQ), etc.) when you are
concerned about ambient noise.
Select the best microphone sensitivity according to
the situation. Please try to lower the setting of the
