  DOP-B07E415, DOP-B07E515, DOP-B08E515, DOP-B10E515, and DOP-B10E615 
models have the audio output function. 
  Only DOP-107EG and DOP-110ES of the DOP-100 replacement models have the audio 
output function. 
  If you open a DOP-B project with audio function on a DOP-100 replacement model that 
does not support this function, the interface for the audio output function is automatically 
removed and the [Audio Output Setting] in the [Options] drop-down list becomes 
unavailable. 
  The following figures show the difference when you open a DOP-B07E415 project on 
DOP-107EV.
