Library browsing is not possible.

Is a medium on which library information is recorded loaded?

The library browse mode is only set when media on which library information is recorded are loaded. When a medium on which no library information is recorded is loaded, the folder browse mode is set.

Is the USB device write-protected?

Set the USB device so that files can be written on it.

Set the USB device’s write-protect switch to the off position.

Nothing is displayed. Is the auto standby function activated?

This unit is shipped with the auto standby function turned on. If you do not want to use the auto standby function, set [AUTO STANDBY] to [OFF]. (page 25)
