•  This unit can recognize a total of 512 files, of 200 

folders, and of 8 hierarchies.

•  This unit can play back files recorded in VBR (variable 

bit rate).

  Files recorded in VBR have a discrepancy in elapsed 

time display, and do not show the actual elapsed 
time. Especially, after performing the search function, 
this difference becomes noticeable.

•  The search function works but search speed is not 

constant.
