Estimated available recording time (with internal 2GB memory)
* If you record multiple files, the total available recording time will be shorter than those estimated above.
* When you purchase the recorder, the Owner’s Manual and Reference Manual are stored in PDF format in the internal
memory. Therefore, the actual available recording time is less than the above time.
* The largest available recording space (for continuous recording) in one file is 2GB.

About the ALC (Auto Level Control) function
The Auto Level Control function automatically adjusts the recording level in response to the
source level so that the resulting recording will be tighter dynamically.

Feature
The recording will accurately rep-
resent the original sound, and
maintain sound dynamics as is. The recording dynamics will be adjusted. Louder sounds
will be quieter and softer sounds will be louder. This setting
will reduce distortion and is better for recording dictation.
Application
