It takes a long time to transfer and register music files to
the HDD AUDIO PLAYER.
We recommend using a wired LAN when you transfer music files stored on your computer to
the HDD AUDIO PLAYER.
When the HDD AUDIO PLAYER is connected to a computer through a wired LAN, file
transfers will take the following time (as a rough guide):
10 FLAC (44.1 kHz/16 bits) files: approximately 5 minutes
3,000 FLAC (44.1 kHz/16 bits) files: approximately one day
Transfer of music files via the network may be severely affected by conditions such as the
router or other devices you are using, signal conditions in the area or the status of the HDD
AUDIO PLAYER.
Transfer and analysis of the music files are done in parallel by the HDD AUDIO PLAYER.
Therefore, it may take some time before music file registration is completed.
