Various Ways of Recording
Starting recording automatically in response to the sound
— Advanced VOR function
When VOR (voice operated recording) selector on the rear is set to ON,
recording starts when the recorder detects sound and stops when no
sound is heard.
Note
VOR function is affected by the sound around you. Set the MIC SENS selector
to either H or L (see page 14). If recording is not satisfactory after you have
changed the microphone sensitivity, or for important recording, set the VOR
selector to OFF.
Recording with an external microphone or from other
equipment
Connect a plug-in-power type microphone or other equipment to the MIC
(PLUG IN POWER) jack.
When you connect an external microphone, the built-in microphone is
automatically cut off. When a plug-in-power type microphone is
connected, power is automatically supplied to the microphone from the IC
recorder.
Adding a recording
To add a recording to a previously recorded message or to add an
overwrite recording during playback, see pages 24 and 25.
