You can make the playback sound well-balanced and more audible by
amplifying only the inaudible low-level part of a recorded message and
adjusting the overall recording to its optimum level (Digital Voice Up
function). This function is useful to hear a meeting with each speaker's
voice more audible.
During playback or stop, slide the VOICE UP switch to “ON”.
The message is played back with adjusted sound.
To resume normal playback
Slide the VOICE UP switch to “OFF”.
