•Adjust the position of the built-in microphone.
•To record a sound centering on a specific
direction, slide the DIRECTNL switch to “ON”
position. When you record a sound at a
conference/meeting or in a spacious place etc.,

modes, see page 54.
To record a sound not centering on a specific direction (all-
directional recording)
Slide the DIRECTNL switch to “OFF”position.
To select the sensitivity of the built-in microphone
You can select the microphone sensitivity by setting the SENS (page 54) in
the menu according to the recording conditions:
•H (high): To record a small sound at a meeting or in a quiet and/or
spacious place.
•L (low): To record for dictation or in a noisy place.

Basic Operations
15GB
Using Convenient Functions while Recording
To monitor the recording
When recording from the built-in microphone, you connect an ear receiver
supplied or not supplied to the i (headphones) jack and monitor the
recording from the connected ear receiver. You can adjust the volume with
VOL +/–, but the recording level is fixed.
Note
If you turn up the volume excessively or place the ear receiver near the
microphone while monitoring recording, the microphone may pick up the
sound from the ear receiver, causing acoustic feedback (howling sound).
Starting recording automatically in response to the sound
—Advanced VOR function
You can set the VOR (voice operated recording) function in the menu.
With VOR set to ON, recording starts when the recorder detects sound,
and “VOR”appears in the display window. The recording pauses when
no sound is detected, and “VOR PAUSE”appears. You can change the
VOR setting with the menu during recording (page 54).
Notes
•VOR function is affected by the sound around you. Set the SENS (page 54)
according to the recording conditions. If recording is not satisfactory after you
have changed the microphone sensitivity, or for important recording, set the
VOR to OFF.
•When you use this IC recorder for important recording, set the VOR to OFF.
