File Operation Problems
No sound comes out when a video is played.
Cause What to do
The Audio Codec of the
file is not supported.
Check the file format. See
“Supported Video Formats” on
page 32 or “Supported Audio
Formats” on page 38 for details.
You cannot copy a file or files.
Cause What to do
There is not enough space
available on the hard drive
to copy all of the files on the
memory card.
Check the hard drive space. See
“Device Information” on page 70.
Delete unnecessary files or reduce
the number of files to copy from the
memory card.
The viewer’s hard drive
space doesn’t increase, even
though data has been
deleted.
If you’ve connected the viewer to
your computer, it’s best to delete
files using the Link2 software, or
data may not be removed
completely. Check the Recycle Bin
(Windows) or Trash (Macintosh)
and empty it to clear any files.
You cannot copy files from
an external USB device.
Connect the AC adapter to the
viewer. If the external USB device
has its own power adapter, connect
it too.
You cannot delete a file.
Cause What to do
The file is locked. Unlock the file and then delete it.
See “Locking Files and Folders” on
page 57 and “Deleting Files and
Folders” on page 55.
You cannot use the buttons on the viewer.
Cause What to do
The buttons are deactivated
because the power switch is
set to
Hold.
Slide the power switch back to the
middle position.
You cannot set/unset a folder as private.
Cause What to do
The password is incorrect. If you forget the password, enter
5555, 7777, then 3333 to reset it to
the default (0000).
