(Internal Memory/Music)
The data can be copied/erased by the operations on the Setup screen. (When erasing the data, execute formatting the
internal memory.)
Note 1:
When replacing the SY-164 board, erase the data in internal memory of the board before replacement.

using a battery pack with little remaining charge, the battery pack may run out, causing copying to fail or 
possibly corrupting the data.
• You cannot copy individual images.
• The original images in the internal memory are retained even after copying. To delete the contents of the 
internal memory, remove the “Memory Stick Duo” after copying, then execute the [Format] command in 
(Internal Memory)..
• You cannot select a folder copied on a “Memory Stick Duo”.
• Even if you copy data, a 
 (Print order) mark is not copied.
